Buddhism is a religion and philosophy encompassing a variety of traditions, beliefs and practices, largely based on teachings attributed to Siddhartha Gautama, commonly known as the Buddha (Pāli/Sanskrit "the awakened one"), and is classified as an Indian religion. The Buddha lived and taught in the northeastern Indian subcontinent sometime between the 6th and 4th centuries BCE. He is recognized by adherents as an awakened teacher who shared his insights to help sentient beings end suffering (or dukkha), achieve nirvana, and escape what is seen as a cycle of suffering and rebirth.
Two major branches of Buddhism are recognized: Theravada ("The School of the Elders") and Mahayana ("The Great Vehicle"). Theravada—the oldest surviving branch—has a widespread following in Sri Lanka and Southeast Asia, and Mahayana is found throughout East Asia and includes the traditions of Pure Land, Zen, Nichiren Buddhism, Tibetan Buddhism, Shingon, Tendai and Shinnyo-en. In some classifications Vajrayana, a subcategory of Mahayana, is recognized as a third branch. While Buddhism remains most popular within Asia, both branches are now found throughout the world. Various sources put the number of Buddhists in the world at between 230 million and 500 million, making it the world's fourth-largest religion.
Buddhist schools vary significantly on the exact nature of the path to liberation, the importance and canonicity of various teachings and scriptures, and especially their respective practices. The foundations of Buddhist tradition and practice are the Three Jewels: the Buddha, the Dharma (the teachings), and the Sangha (the community). Taking "refuge in the triple gem" has traditionally been a declaration and commitment to being on the Buddhist path and in general distinguishes a Buddhist from a non-Buddhist. Other practices may include following ethical precepts, support of the monastic community, renouncing conventional living and becoming a monastic, meditation (this category includes mindfulness), cultivation of higher wisdom and discernment, study of scriptures, devotional practices, ceremonies, and in the Mahayana tradition, invocation of buddhas and bodhisattvas.
Life of the Buddha
According to the Theravada Tipitaka scriptures, shortly after the birth of prince Siddhartha Gautama, an astrologer visited the young prince's father, King Śuddhodana, and prophesied that Siddhartha would either become a great king or renounce the material world to become a holy man, depending on whether he saw what life was like outside the palace walls.
Śuddhodana was determined to see his son become a king so he prevented him from leaving the palace grounds. But at age 29, despite his father's efforts, Siddhartha ventured beyond the palace several times. In a series of encounters known in Buddhist literature as the four sights he learned of the suffering of ordinary people, encountering an old man, a sick man, a corpse and, finally, an ascetic holy man, apparently content and at peace with the world. These experiences prompted Gautama to abandon royal life and take up a spiritual quest.
Gautama first went to study with famous religious teachers of the day, and mastered the meditative attainments they taught. But he found that they did not provide a permanent end to suffering, so he continued his quest. He next attempted an extreme asceticism, which was a religious pursuit common among the Shramanas. Gautama underwent prolonged fasting, breath-holding, and exposure to pain. He almost starved himself to death in the process. He realized that he had taken this kind of practice to its limit, and had not put an end to suffering. So in a pivotal moment he accepted milk and rice from a village girl and changed his approach. He devoted himself to anapanasati meditation, through which he discovered what Buddhists call the Middle Way: a path of moderation between the extremes of self-indulgence and self-mortification.
Gautama was now determined to complete his spiritual quest. At the age of 35, he famously sat in meditation under a sacred fig tree—known as the Bodhi tree—in the town of Bodh Gaya, India, and vowed not to rise before achieving enlightenment. After many days, he finally destroyed the fetters of his mind, thereby liberating himself from the cycle of suffering and rebirth, and arose as a fully enlightened being. Soon thereafter, he attracted a band of followers and instituted a monastic order. As the Buddha (meaning "the awakened one" or "the enlightened one"), he spent the rest of his life teaching the path of awakening he discovered, traveling throughout the northeastern part of the Indian subcontinent, and died at the age of 80 (483 BCE) in Kushinagar, India.
The above narrative draws on the early scriptures. Later texts such as the Mahayana Lalitavistara Sutra give different accounts.
Scholars are hesitant to make unqualified claims about the historical facts of the Buddha's life. Most accept that he lived, taught and founded a monastic order, but do not consistently accept the details in his biographies. According to author Michael Carrithers, while there are good reasons to doubt the traditional account, "the outline of the life must be true: birth, maturity, renunciation, search, awakening and liberation, teaching, death."
In writing her biography of Buddha, Karen Armstrong noted, "It is obviously difficult, therefore, to write a biography of the Buddha that will meet modern criteria, because we have very little information that can be considered historically sound... [but] we can be reasonably confident Siddhatta Gotama did indeed exist and that his disciples preserved the memory of his life and teachings as well as they could"
Life and the world
Karma as the law of cause and effect
Karma (from Sanskrit: "action, work") in Buddhism is the force that drives saṃsāra—the cycle of suffering and rebirth for each being. Good, skillful deeds (Pāli: "kusala") and bad, unskillful (Pāli: "akusala") actions produce "seeds" in the mind which come to fruition either in this life or in a subsequent rebirth. The avoidance of unwholesome actions and the cultivation of positive actions is called śīla (from Sanskrit: "ethical conduct").
In Buddhism, karma specifically refers to those actions (of body, speech, and mind) that spring from mental intent ("cetana"), and which bring about a consequence (or fruit, "phala") or result ("vipāka"). Every time a person acts there is some quality of intention at the base of the mind and it is that quality rather than the outward appearance of the action that determines its effect.
In Theravada Buddhism there can be no divine salvation or forgiveness for one's karma, since it is a purely impersonal process that is a part of the makeup of the universe. Some Mahayana traditions hold different views. For example, the texts of certain Mahayana sutras (such as the Lotus Sutra, the Angulimaliya Sutra and the Nirvana Sutra) claim that reciting or merely hearing their texts can expunge great swathes of negative karma. Some forms of Buddhism (for example, Vajrayana) regard the recitation of mantras as a means for cutting off previous negative karma. The Japanese Pure Land teacher Genshin taught that Amida Buddha has the power to destroy the karma that would otherwise bind one in saṃsāra.
Rebirth refers to a process whereby beings go through a succession of lifetimes as one of many possible forms of sentient life, each running from conception to death. Buddhism rejects the concepts of a permanent self or an unchanging, eternal soul, as it is called in Hinduism and Christianity. According to Buddhism there ultimately is no such thing as a self independent from the rest of the universe (the doctrine of anatta). Rebirth in subsequent existences must be understood as the continuation of a dynamic, ever-changing process of "dependent arising" ("pratītyasamutpāda") determined by the laws of cause and effect (karma) rather than that of one being, transmigrating or incarnating from one existence to the next.
Each rebirth takes place within one of five realms according to Theravadins, or six according to other schools. These are further subdivided into 31 planes of existence:
- Naraka beings: those who live in one of many Narakas (Hells)
- Preta: sometimes sharing some space with humans, but invisible to most people; an important variety is the hungry ghost
- Animals: sharing space with humans, but considered another type of life
- Human beings: one of the realms of rebirth in which attaining Nirvana is possible
- Asuras: variously translated as lowly deities, demons, titans, antigods; not recognized by Theravāda (Mahavihara) tradition as a separate realm
- Devas including Brahmas: variously translated as gods, deities, spirits, angels, or left untranslated
Rebirths in some of the higher heavens, known as the Śuddhāvāsa Worlds (Pure Abodes), can be attained only by skilled Buddhist practitioners known as anāgāmis (non-returners). Rebirths in the arupa-dhatu (formless realms) can be attained only by those who can meditate on the arūpajhānas, the highest object of meditation.
According to East Asian and Tibetan Buddhism, there is an intermediate state (Tibetan "Bardo") between one life and the next. The orthodox Theravada position rejects this; however there are passages in the Samyutta Nikaya of the Pali Canon (the collection of texts on which the Theravada tradition is based), that seem to lend support to the idea that the Buddha taught of an intermediate stage between one life and the next.
The cycle of saṃsāra
Sentient beings crave pleasure and are averse to pain from birth to death. In being controlled by these attitudes, they perpetuate the cycle of conditioned existence and suffering (saṃsāra), and produce the causes and conditions of the next rebirth after death. Each rebirth repeats this process in an involuntary cycle, which Buddhists strive to end by eradicating these causes and conditions, applying the methods laid out by the Buddha and subsequent Buddhists.
Suffering's causes and solution
The Four Noble Truths
According to the Pali Tipitaka, the Four Noble Truths were the first teaching of Gautama Buddha after attaining Nirvana. They are sometimes considered to contain the essence of the Buddha's teachings:
- Life as we know it ultimately is or leads to suffering/uneasiness (dukkha) in one way or another.
- Suffering is caused by craving. This is often expressed as a deluded clinging to a certain sense of existence, to selfhood, or to the things or phenomena that we consider the cause of happiness or unhappiness. Craving also has its negative aspect, i.e. one craves that a certain state of affairs not exist.
- Suffering ends when craving ends. This is achieved by eliminating delusion, thereby reaching a liberated state of Enlightenment (bodhi);
- Reaching this liberated state is achieved by following the path laid out by the Buddha.
This method is described by early Western scholars, and taught as an introduction to Buddhism by some contemporary Mahayana teachers (for example, the Dalai Lama).
According to other interpretations by Buddhist teachers and scholars, lately recognized by some Western non-Buddhist scholars, the "truths" do not represent mere statements, but are categories or aspects that most worldly phenomena fall into, grouped in two:
- Suffering and causes of suffering
- Cessation and the paths towards liberation from suffering.
Thus, according to the Macmillan Encyclopedia of Buddhism they are
- "The noble truth that is suffering"
- "The noble truth that is the arising of suffering"
- "The noble truth that is the end of suffering"
- "The noble truth that is the way leading to the end of suffering"
The early teaching and the traditional Theravada understanding is that the Four Noble Truths are an advanced teaching for those who are ready for them. The East Asian Mahayana position is that they are a preliminary teaching for people not yet ready for the higher and more expansive Mahayana teachings.They are little known in the Far East.. Within the Nalanda/Tibetan tradition of Mahayana Buddhism, the Four Noble Truths remain essential to the path.
The Noble Eightfold Path
The Noble Eightfold Path—the fourth of the Buddha's Noble Truths—is the way to the cessation of suffering (dukkha). It has eight sections, each starting with the word "samyak" (Sanskrit, meaning "correctly", "properly", or "well", frequently translated into English as "right"), and presented in three groups known as the three higher trainings. (NB: Pāli transliterations appear in brackets after Sanskrit ones):
- Prajñā is the wisdom that purifies the mind, allowing it to attain spiritual insight into the true nature of all things. It includes:
- dṛṣṭi (ditthi): Right view: viewing reality as it is, not just as it appears to be; and viewing without judging.
- saṃkalpa (sankappa): Right intention: intention of renunciation, freedom and harmlessness. This includes accepting life the way it really is and not wishing it was something else.
- Śīla is the ethics or morality, or abstention from unwholesome deeds. It includes:
- vāc (vāca): Right speech: speaking in a truthful and non-hurtful way; speaking directly and without hedging.
- karman (kammanta): Right action: acting in a non-harmful and disciplined way.
- ājīvana (ājīva): Right livelihood: a non-harmful livelihood; not avoiding work.
- Samādhi is the mental discipline required to develop mastery over one’s own mind. This is done through the practice of various contemplative and meditative practices, and includes:
- vyāyāma (vāyāma): Right effort: making an effort to improve; striving in a cheerful and creative way.
- smṛti (sati): Right mindfulness: awareness to see things for what they are with clear consciousness, being aware of the present reality within oneself, without any craving or aversion.
- samādhi (samādhi): Right meditation: Meditating correctly, and focusing concentratedly on one's life.
The practice of the Eightfold Path is understood in two ways, as requiring either simultaneous development (all eight items practiced in parallel), or as a progressive series of stages through which the practitioner moves, the culmination of one leading to the beginning of another.
In the early sources (the four main Nikayas) the Eightfold Path was not generally taught to lay people, and today it is little known in the Far East.
An important guiding principle of Buddhist practice is the Middle Way (or Middle Path), which is said to have been discovered by Gautama Buddha prior to his enlightenment. The Middle Way has several definitions:
- The practice of non-extremism: a path of moderation away from the extremes of self-indulgence and self-mortification
- The middle ground between certain metaphysical views (for example, that things ultimately either do or do not exist)
- An explanation of Nirvana (perfect enlightenment), a state wherein it becomes clear that all dualities apparent in the world are delusory (see Seongcheol)
- Another term for emptiness, the ultimate nature of all phenomena (in the Mahayana branch), a lack of inherent existence, which avoids the extremes of permanence and nihilism or inherent existence and nothingness
The way things are
Buddhist scholars have produced a remarkable quantity of intellectual theories, philosophies and world view concepts (see, for example, Abhidharma, Buddhist philosophy and Reality in Buddhism). Some schools of Buddhism discourage doctrinal study, and some regard it as essential, but most regard it as having a place, at least for some persons at some stages in Buddhist practice.
In the earliest Buddhist teachings, shared to some extent by all extant schools, the concept of liberation (Nirvana)—the goal of the Buddhist path—is closely related to the correct understanding of how the mind causes stress. In awakening to the true nature of clinging, one develops dispassion for the objects of clinging, and is liberated from suffering (dukkha) and the cycle of incessant rebirths (saṃsāra). To this end, the Buddha recommended viewing things as characterized by the three marks of existence.
Impermanence, suffering and not-self
Anicca (Pāli for "inconstancy", usually translated as impermanence) is one of the three marks of existence. The term expresses the Buddhist notion that all compounded or conditioned phenomena (all things and experiences) are inconstant, unsteady, and impermanent. Everything we can experience through our senses is made up of parts, and its existence is dependent on external conditions. Everything is in constant flux, and so conditions and the thing itself are constantly changing. Things are constantly coming into being, and ceasing to be. Since nothing lasts, there is no inherent or fixed nature to any object or experience.
According to the impermanence doctrine, human life embodies this flux in the aging process, the cycle of rebirth (saṃsāra), and in any experience of loss. The doctrine asserts that because things are impermanent, attachment to them is futile and leads to suffering (dukkha).
Suffering or dukkha (Pāli दुक्ख; Sanskrit दुःख duḥkha, which according to grammatical tradition derived from dus-kha "uneasy", but according to Monier-Williams more likely a Prakritized form of dus-stha "unsteady, disquieted") is a central concept in Buddhism. The word roughly corresponds to a number of terms in English including suffering, pain, unsatisfactoriness, sorrow, affliction, anxiety, dissatisfaction, discomfort, anguish, stress, misery, and frustration. Although dukkha is often translated as "suffering", its philosophical meaning is more analogous to "disquietude" as in the condition of being disturbed. As such, "suffering" is too narrow a translation with "negative emotional connotations" which can give the impression that the Buddhist view is one of pessimism, but Buddhism seeks to be neither pessimistic nor optimistic, but realistic. Thus in English-language Buddhist literature "dukkha" is often left untranslated, so as to encompass its full range of meaning.
Anatta (Pāli) or anātman (Sanskrit) refers to the notion of "not-self". Upon careful examination, one finds that no phenomenon is really "I" or "mine"; these concepts are in fact constructed by the mind. In the Nikayas anatta is not meant as a metaphysical assertion, but as an approach for gaining release from suffering. In fact, the Buddha rejected both of the metaphysical assertions "I have a Self" and "I have no Self" as ontological views that bind one to suffering. When asked if the self was identical with the body, the Buddha refused to answer. By analyzing the constantly changing physical and mental constituents (skandhas) of a person or object, the practitioner comes to the conclusion that neither the respective parts nor the person as a whole comprise a self.
The doctrine of pratītyasamutpāda (Sanskrit; Pali: paticcasamuppāda; Tibetan: rten.cing.'brel.bar.'byung.ba; Chinese: 緣起) is an important part of Buddhist metaphysics. It states that phenomena arise together in a mutually interdependent web of cause and effect. It is variously rendered into English as "dependent origination", "conditioned genesis", "dependent co-arising", "interdependent arising", or "contingency".
The best-known application of the concept of pratītyasamutpāda is the scheme of Twelve Nidānas (from Pāli "nidāna" meaning "cause, foundation, source or origin"), which explain the continuation of the cycle of suffering and rebirth (saṃsāra) in detail.
The Twelve Nidānas describe a causal connection between the subsequent characteristics or conditions of cyclic existence, each one giving rise to the next:
- Avidyā: ignorance, specifically spiritual ignorance of the nature of reality
- Saṃskāras: literally formations, explained as referring to karma
- Vijñāna: consciousness, specifically discriminative
- Nāmarūpa: literally name and form, referring to mind and body
- Ṣaḍāyatana: the six sense bases: eye, ear, nose, tongue, body and mind-organ
- Sparśa: variously translated contact, impression, stimulation (by a sense object)
- Vedanā: usually translated feeling: this is the "hedonic tone", i.e. whether something is pleasant, unpleasant or neutral
- Tṛṣṇā: literally thirst, but in Buddhism nearly always used to mean craving
- Upādāna: clinging or grasping; the word also means fuel, which feeds the continuing cycle of rebirth
- Bhava: literally being (existence) or becoming. (The Theravada explains this as having two meanings: karma, which produces a new existence, and the existence itself.)
- Jāti: literally birth, but life is understood as starting at conception
- Jarāmaraṇa: (old age and death) and also śokaparidevaduḥkhadaurmanasyopāyāsa (sorrow, lamentation, pain, sadness, and misery)
Sentient beings always suffer throughout saṃsāra, until they free themselves from this suffering by attaining Nirvana. Then the absence of the first Nidāna—ignorance—leads to the absence of the others.
Mahayana Buddhism received significant theoretical grounding from Nagarjuna (perhaps c. 150–250 CE), arguably the most influential scholar within the Mahayana tradition. Nagarjuna's primary contribution to Buddhist philosophy was the systematic exposition of the concept of śūnyatā, or "emptiness," widely attested in the Prajñāpāramitā sutras which were emergent in his era. The concept of emptiness brings together other key Buddhist doctrines, particularly anatta and pratītyasamutpāda (dependent origination), to refute the metaphysics of Sarvastivada and Sautrantika (extinct non-Mahayana schools). For Nagarjuna, it is not merely sentient beings that are empty of ātman; all phenomena (dharmas) are without any svabhava (literally "own-nature" or "self-nature"), and thus without any underlying essence; they are "empty" of being independent; thus the heterodox theories of svabhava circulating at the time were refuted on the basis of the doctrines of early Buddhism. Nagarjuna's school of thought is known as the Mādhyamaka. Some of the writings attributed to Nagarjuna made explicit references to Mahayana texts, but his philosophy was argued within the parameters set out by the agamas. He may have arrived at his positions from a desire to achieve a consistent exegesis of the Buddha's doctrine as recorded in the Canon. In the eyes of Nagarjuna the Buddha was not merely a forerunner, but the very founder of the Mādhyamaka system.
Sarvastivada teachings—which were criticized by Nāgārjuna—were reformulated by scholars such as Vasubandhu and Asanga and were adapted into the Yogacara (Sanskrit: yoga practice) school. While the Mādhyamaka school held that asserting the existence or non-existence of any ultimately real thing was inappropriate, some exponents of Yogacara asserted that the mind and only the mind is ultimately real (a doctrine known as cittamatra). Not all Yogacarins asserted that mind was truly existent; Vasubandhu and Asanga in particular did not. These two schools of thought, in opposition or synthesis, form the basis of subsequent Mahayana metaphysics in the Indo-Tibetan tradition.
Besides emptiness, Mahayana schools often place emphasis on the notions of perfected spiritual insight (prajñāpāramitā) and Buddha-nature (tathāgatagarbha, meaning "Buddha embryo" or "Buddha-matrix"). According to the Tathāgatagarbha Sutras, the Buddha revealed the reality of the deathless Buddha-nature, which is said to be inherent in all sentient beings and enables them all eventually to reach complete enlightenment, i.e. Buddhahood. Buddha-nature is stated in the Mahayana Angulimaliya Sutra and Mahaparinirvana Sutra to not be śūnya, but to be replete with eternal Buddhic virtues. In the Tathāgatagarbha Sutras the Buddha is portrayed proclaiming that the teaching of the tathāgatagarbha constitutes the "absolutely final culmination" of his Dharma—the highest presentation of truth (other sūtras make similar statements about other teachings) and it has traditionally been regarded as the highest teaching in East Asian Buddhism. However, in modern China all doctrines are regarded as equally valid. The Mahayana can also on occasion communicate a vision of the Buddha or Dharma which amounts to mysticism and gives expression to a form of mentalist panentheism (see God in Buddhism).
Speculation versus direct experience in Buddhist epistemology
Decisive in distinguishing Buddhism from other schools of Indian philosophy is the issue of epistemological justification. While all schools of Indian logic recognize various sets of valid justifications for knowledge (pramana) Buddhism recognizes a smaller set than do the others. All accept perception and inference, for example, but for some schools of Buddhism the received textual tradition is an equally valid epistemological category.
According to the scriptures, during his lifetime the Buddha remained silent when asked several metaphysical questions. These regarded issues such as whether the universe is eternal or non-eternal (or whether it is finite or infinite), the unity or separation of the body and the self, the complete inexistence of a person after Nirvana and death, and others. One explanation for this silence is that such questions distract from activity that is practical to realizing enlightenment and bring about the danger of substituting the experience of liberation by conceptual understanding of the doctrine or by religious faith. Another explanation is that both affirmative and negative positions regarding these questions are based on attachment to and misunderstanding of the aggregates and senses. That is, when one sees these things for what they are, the idea of forming positions on such metaphysical questions simply does not occur to one. Another closely related explanation is that reality is devoid of designations, or empty, and therefore language itself is a priori inadequate.
Thus, the Buddha's silence does not indicate misology or disdain for philosophy. Rather, it indicates that he viewed these questions as not leading to true knowledge. Dependent arising provides a framework for analysis of reality that is not based on metaphysical assumptions regarding existence or non-existence, but instead on direct cognition of phenomena as they are presented to the mind. This informs and supports the Buddhist approach to liberation via the Noble Eightfold Path.
The Buddha of the earliest Buddhists texts describes Dharma (in the sense of "truth") as "beyond reasoning" or "transcending logic", in the sense that reasoning is a subjectively introduced aspect of the way humans perceive things, and the conceptual framework which underpins it is a part of the cognitive process, rather than a feature of things as they really are. Being "beyond reasoning" means in this context penetrating the nature of reasoning from the inside, and removing the causes for experiencing any future stress as a result of it, rather than functioning outside of the system as a whole.
Most Buddhists agree that, to a greater or lesser extent, words are inadequate to describe the goal of the Buddhist path, but concerning the usefulness of words in the path itself, schools differ radically.
In the Mahayana Mahaparinirvana Sutra, the Buddha insists that while pondering upon Dharma is vital, one must then relinquish fixation on words and letters, as these are utterly divorced from liberation and the Buddha-nature. The Tibetan tantra entitled the "All-Creating King" (Kunjed Gyalpo Tantra) also emphasizes how Buddhist truth lies beyond the range of discursive/verbal thought and is ultimately mysterious. Samantabhadra, states there: "The mind of perfect purity ... is beyond thinking and inexplicable..." Also later, the famous Indian Buddhist practitioner and teacher, mahasiddha Tilopa discouraged any intellectual activity in his six words of advice.
Professor C. D. Sebastian describes the nature of enlightenment according to one Mahayana text:
Bodhi is the final goal of a Bodhisattva's career and it is indicated by such words as buddha-jnana (knowledge of Buddha), sarvjnata (omniscience), sarvakarajnata (the quality of knowing things as they are), ... and acintyam jnanam (inconceivable knowledge) ... Bodhi is pure universal and immediate knowledge, which extends over all time, all universes, all beings and elements, conditioned and unconditioned. It is absolute and identical with Reality and thus it is Tathata. Bodhi is immaculate and non-conceptual, and it, being not an outer object, cannot be understood by discursive thought. It has neither beginning, nor middle nor end and it is indivisbile. It is non-dual (advayam)... The only possible way to comprehend it is through samadhi by the yogin
The early texts, in contrast, contain explicit repudiations of attributing omniscience to the Buddha. Furthermore, the non-duality ascribed to the nature of enlightenment in the early texts is not ontological.
Mahayana often adopts a pragmatic concept of truth: doctrines are "true" in the sense of being spiritually beneficial. In modern Chinese Buddhism, all doctrinal traditions are regarded as equally valid.
Theravada promotes the concept of vibhajjavada (Pāli, literally "Teaching of Analysis") to non-Buddhists. This doctrine says that insight must come from the aspirant's experience, critical investigation, and reasoning instead of by blind faith. As the Buddha said according to the canonical scriptures:
Do not accept anything by mere tradition ... Do not accept anything just because it accords with your scriptures ... Do not accept anything merely because it agrees with your pre-conceived notions ... But when you know for yourselves—these things are moral, these things are blameless, these things are praised by the wise, these things, when performed and undertaken, conduce to well-being and happiness—then do you live acting accordingly.
Nirvana (Sanskrit; Pali: "Nibbana") means "cessation", "extinction" (of craving and ignorance and therefore suffering and the cycle of involuntary rebirths (saṃsāra), "extinguished", "quieted", "calmed"; it is also known as "Awakening" or "Enlightenment" in the West. The term for anybody who has achieved nirvana, including the Buddha, is arahant.
Bodhi (Pāli and Sanskrit, in devanagari: बॊधि) is a term applied to the experience of Awakening of arahants. Bodhi literally means "awakening", but it is more commonly translated into English as "enlightenment". In Early Buddhism, bodhi carried a meaning synonymous to nirvana, using only some different metaphors to describe the experience, which implies the extinction of raga (greed, craving), dosa (hate, aversion) and moha (delusion). In the later school of Mahayana Buddhism, the status of nirvana was downgraded in some scriptures, coming to refer only to the extinction of greed and hate, implying that delusion was still present in one who attained nirvana, and that one needed to attain bodhi to eradicate delusion:
An important development in the Mahayana [was] that it came to separate nirvana from bodhi ('awakening' to the truth, Enlightenment), and to put a lower value on the former (Gombrich, 1992d). Originally nirvana and bodhi refer to the same thing; they merely use different metaphors for the experience. But the Mahayana tradition separated them and considered that nirvana referred only to the extinction of craving (passion and hatred), with the resultant escape from the cycle of rebirth. This interpretation ignores the third fire, delusion: the extinction of delusion is of course in the early texts identical with what can be positively expressed as gnosis, Enlightenment.—Richard F. Gombrich, How Buddhism Began
Therefore, according to Mahayana Buddhism, the arahant has attained only nirvana, thus still being subject to delusion, while the bodhisattva not only achieves nirvana but full liberation from delusion as well. He thus attains bodhi and becomes a buddha. In Theravada Buddhism, bodhi and nirvana carry the same meaning as in the early texts, that of being freed from greed, hate and delusion.
The term parinirvana is also encountered in Buddhism, and this generally refers to the complete nirvana attained by the arhat at the moment of death, when the physical body expires.
In Theravada doctrine, a person may awaken from the "sleep of ignorance" by directly realizing the true nature of reality; such people are called arahants and occasionally buddhas. After numerous lifetimes of spiritual striving, they have reached the end of the cycle of rebirth, no longer reincarnating as human, animal, ghost, or other being. The commentaries to the Pali Canon classify these awakened beings into three types:
- Sammasambuddha, usually just called Buddha, who discovers the truth by himself and teaches the path to awakening to others
- Paccekabuddha, who discovers the truth by himself but lacks the skill to teach others
- Savakabuddha, who receive the truth directly or indirectly from a Sammasambuddha
Bodhi and nirvana carry the same meaning, that of being freed from craving, hate, and delusion. In attaining bodhi, the arahant has overcome these obstacles. As a further distinction, the extinction of only hatred and greed (in the sensory context) with some residue of delusion, is called anagami.
In the Mahayana, the Buddha tends not to be viewed as merely human, but as the earthly projection of a beginningless and endless, omnipresent being (see Dharmakaya) beyond the range and reach of thought. Moreover, in certain Mahayana sutras, the Buddha, Dharma and Sangha are viewed essentially as One: all three are seen as the eternal Buddha himself.
Celestial Buddhas are individuals who no longer exist on the material plane of existence, but who still aid in the enlightenment of all beings.
Nirvana came to refer only to the extinction of greed and hate,[dubious ] implying that delusion was still present in one who attained Nirvana. Bodhi became a higher attainment that eradicates delusion entirely. Thus, the Arahant attains Nirvana but not Bodhi, thus still being subject to delusion, while the Buddha attains Bodhi.[dubious ]
The method of self-exertion or "self-power"—without reliance on an external force or being—stands in contrast to another major form of Buddhism, Pure Land, which is characterised by utmost trust in the salvific "other-power" of Amitabha Buddha. Pure Land Buddhism is a very widespread and perhaps the most faith-orientated manifestation of Buddhism and centres upon the conviction that faith in Amitabha Buddha and the chanting of homage to his name will liberate one at death into the "happy land" (安樂) or "pure land" (淨土) of Amitabha Buddha. This Buddhic realm is variously construed as a foretaste of Nirvana, or as essentially Nirvana itself. The great vow of Amitabha Buddha to rescue all beings from samsaric suffering is viewed within Pure Land Buddhism as universally efficacious, if only one has faith in the power of that vow or chants his name.
Nearly all Chinese Buddhists accept that the chances of attaining sufficient enlightenment by one's own efforts are very slim,[dubious ] so that Pure Land practice is essential as an "insurance policy" even if one practises something else.
Buddhists believe Gautama Buddha was the first to achieve enlightenment in this Buddha era and is therefore credited with the establishment of Buddhism. A Buddha era is the stretch of history during which people remember and practice the teachings of the earliest known Buddha. This Buddha era will end when all the knowledge, evidence and teachings of Gautama Buddha have vanished. This belief therefore maintains that many Buddha eras have started and ended throughout the course of human existence. The Gautama Buddha, then, is the Buddha of this era, who taught directly or indirectly to all other Buddhas in it (see types of Buddhas).
In addition, Mahayana Buddhists believe there are innumerable other Buddhas in other universes. A Theravada commentary says that Buddhas arise one at a time in this world element, and not at all in others.
The idea of the decline and gradual disappearance of the teaching has been influential in East Asian Buddhism. Pure Land Buddhism holds that it has declined to the point where few, if any, are capable of following the path, so most or all must rely on the power of the Buddha Amitabha. Zen and Nichiren traditionally hold that most are incapable of following the "complicated" paths of some other schools and present what they view as a simple practice instead.
