In the Ganges basin of northern India, around the 5th century BCE, with the teaching career of Siddhartha Gautama, the Buddha.

SOURCES: Pali Canon; R. Gethin, The Foundations of Buddhism

The Buddha's awakening and forty-five years of teaching; the founding of the monastic order (sangha); the early councils that recited and organized his teaching after his death; and Emperor Ashoka's patronage (3rd century BCE), which carried the message across India and beyond.

SOURCES: Vinaya Pitaka; the Edicts of Ashoka; Gethin, The Foundations of Buddhism

The Buddha himself; close disciples such as Ananda (who recited the discourses) and Sariputta; the monastic communities that memorized and transmitted the canon; later, thinkers like Nagarjuna for the Mahayana, and the translator-monks who carried the texts to China and Tibet.

SOURCES: Pali Canon; Gethin, The Foundations of Buddhism

South to Sri Lanka and Southeast Asia (the Theravada school); along the Silk Road to China, Korea, and Japan (Mahayana); and to Tibet (Vajrayana) — carried by monks, merchants, and royal patronage. It had nearly vanished from its Indian homeland by the medieval period.

Buddhist texts teach that the deepest problem is dukkha — the suffering and unsatisfactoriness running through ordinary life — driven by craving and ignorance. Even pleasures fail to satisfy, because everything we grasp at is impermanent.

SOURCES: Dhammacakkappavattana Sutta (Samyutta Nikaya 56.11); W. Rahula, What the Buddha Taught

Not from a devil or a divine test: the Pali Canon traces suffering to craving (tanha) and ignorance, unfolding through a chain of causes called dependent origination. Evil acts spring from greed, hatred, and delusion in the human mind.

SOURCES: Samyutta Nikaya 12 (dependent origination); Rahula, What the Buddha Taught

The break is in perception itself: we see permanence where everything changes, and a solid self where there is only a changing process — and we build our lives on that mistake. From this ignorance grow craving, aversion, and the suffering they carry.

SOURCES: Anatta-lakkhana Sutta (Samyutta Nikaya 22.59); Dhammapada 277–279

Nirvana: the complete extinguishing of craving, hatred, and delusion, and with them the end of suffering and of the cycle of rebirth. The texts insist this is attainable in this very life.

SOURCES: Dhammacakkappavattana Sutta (Samyutta Nikaya 56.11); Dhammapada 203–204

The Noble Eightfold Path: right view, intention, speech, action, livelihood, effort, mindfulness, and concentration — usually summarized as ethical conduct, meditation, and wisdom. It is a training walked step by step, not a creed to affirm.

SOURCES: Dhammacakkappavattana Sutta (Samyutta Nikaya 56.11); Rahula, What the Buddha Taught

Fully solved, for anyone who completes the path: the third noble truth states that suffering can end without remainder, and the tradition holds up the Buddha and the arahants as proof that it has been done.

SOURCES: Dhammacakkappavattana Sutta (Samyutta Nikaya 56.11); Rahula, What the Buddha Taught

The person is remade — greed gives way to generosity, hatred to lovingkindness, delusion to wisdom. Society changes through the sangha's example and the lay ethics of non-harm; the Mahayana widens the goal to the liberation of all beings.

SOURCES: Dhammapada 183; Shantideva, Bodhicaryavatara

The Dhamma — the way things actually are, discovered (not invented) by the Buddha in his awakening and confirmed in the practitioner's own experience. His word carries the weight of testimony from one who saw, not of revelation from a god.

SOURCES: Ariyapariyesana Sutta (Majjhima Nikaya 26); Rahula, What the Buddha Taught

Chiefly personal experience and reason, trained by practice and guided by the Buddha's teaching. The Kalama Sutta tells inquirers not to accept a claim merely from tradition, scripture, or a teacher's prestige, but to test it by its fruits.

SOURCES: Kalama Sutta (Anguttara Nikaya 3.65); Rahula, What the Buddha Taught

Because it invites verification: the Dhamma is described as «come and see for yourself» (ehipassiko), to be confirmed here and now by the wise. Trust grows as the practice delivers what it promises — calmer, clearer, less grasping minds.

SOURCES: Kalama Sutta (Anguttara Nikaya 3.65); Rahula, What the Buddha Taught

By fruits and by consistency: teachings that lead to greed, hatred, and harm are to be abandoned; those that lead to welfare adopted. For doctrine, the Mahaparinibbana Sutta gives four tests — any claim must be checked against the discourses and the monastic rule before it is accepted.

SOURCES: Kalama Sutta (Anguttara Nikaya 3.65); Mahaparinibbana Sutta (Digha Nikaya 16)

Real and built into reality: wholesome and unwholesome actions carry consequences by the natural law of karma, not by divine command or social convention. What societies call right can be mistaken; the moral order itself is not made up.

SOURCES: Dhammapada 1–2, 127; Nibbedhika Sutta (Anguttara Nikaya 6.63)

Yes — Buddhist texts teach that a trained mind can know realities beyond the physical, such as past lives and the workings of karma, as the Buddha reported from the night of his awakening. Yet some questions he set aside as unhelpful to answer, like whether the world is eternal.

SOURCES: Maha-Saccaka Sutta (Majjhima Nikaya 36); Cula-Malunkya Sutta (Majjhima Nikaya 63)

The Dhamma itself is held to be timeless — the Buddha discovered a law he did not create, and appointed no successor: the teaching is the teacher. But understanding unfolds: the Mahayana added whole bodies of sutras it regards as deeper turnings of the same wheel, which the Theravada does not accept.

SOURCES: Mahaparinibbana Sutta (Digha Nikaya 16); P. Williams, Mahayana Buddhism

The Tipitaka («three baskets»): the monastic rule (Vinaya), the Buddha's discourses (Suttas), and systematic philosophy (Abhidhamma) — preserved in Pali by the Theravada. The Mahayana adds sutras such as the Lotus and the Heart Sutra; Tibet preserves its own vast canon, the Kangyur and Tengyur.

SOURCES: Pali Canon; Gethin, The Foundations of Buddhism

Orally, for centuries: monks memorized the discourses in communal recitation, organized them at councils after the Buddha's death, and the Pali Canon was first written down in Sri Lanka around the 1st century BCE. Mahayana sutras appeared later and were translated into Chinese and Tibetan.

SOURCES: Gethin, The Foundations of Buddhism; R. Gombrich, Theravada Buddhism

No divine origin is claimed: the texts present the Buddha as an awakened human being, and their authority rests on his awakening and on the teaching proving true in practice. Preservation was by disciplined oral tradition — impressive, but never claimed to be miraculously guarded word for word.

SOURCES: Mahaparinibbana Sutta (Digha Nikaya 16); Gethin, The Foundations of Buddhism

The great themes are suffering and its end, impermanence, non-self, karma, ethics, and meditation. The style is oral: numbered lists, heavy repetition, dialogues, and vivid similes — with verse collections like the Dhammapada; Mahayana sutras are more visionary and cosmic in scale.

SOURCES: Gethin, The Foundations of Buddhism

The Four Noble Truths; the Noble Eightfold Path; the three marks of existence (impermanence, suffering, non-self); dependent origination; karma and rebirth; and the Five Precepts for lay life.

SOURCES: Samyutta Nikaya 56.11; Dhammapada 277–279; Rahula, What the Buddha Taught

As practical instruction more than history or law: the Buddha compared his teaching to a raft — used for crossing, not for clinging. Theravada readers stay close to the discourses' plain sense; the Mahayana distinguishes provisional teachings from definitive ones and reads many texts symbolically.

SOURCES: Alagaddupama Sutta (Majjhima Nikaya 22); Williams, Mahayana Buddhism

In the Theravada, Buddhaghosa's Visuddhimagga and the Pali commentaries; in India, the Madhyamaka school of Nagarjuna and the Yogacara of Asanga and Vasubandhu; further east, whole schools of interpretation — Zen, Pure Land, Tiantai, and the Tibetan traditions.

SOURCES: Buddhaghosa, Visuddhimagga; Nagarjuna, Mulamadhyamakakarika; Gethin, The Foundations of Buddhism

Yes: three main canons survive (Pali, Chinese, Tibetan) with overlapping but not identical contents, and the Theravada does not accept the Mahayana sutras as the Buddha's word. Scholars compare the Pali suttas with their Chinese parallels to trace the earliest shared core.

SOURCES: Gethin, The Foundations of Buddhism; Williams, Mahayana Buddhism

The discourses call the Dhamma «well-expounded, visible here and now, inviting one to come and see» — offered to all beings, not to one people. They claim the authority of an awakened teacher, tell hearers to test rather than merely believe, and even to let the teaching go, like a raft, once it has carried them across.

SOURCES: Alagaddupama Sutta (Majjhima Nikaya 22); Mahaparinibbana Sutta (Digha Nikaya 16)

There is no creator God: the Pali Canon teaches that no being made the world or hands down salvation, and it gently satirizes the great god Brahma as himself mortal and mistaken about his own status. Gods (devas) exist, but as impermanent beings inside the cycle, not as the ultimate; the ultimate is nirvana — an unconditioned state, not a person. Later Pure Land devotion to the Buddha Amitabha can look functionally theistic, though he too is no creator.

SOURCES: Kevatta Sutta (Digha Nikaya 11); Brahmajala Sutta (Digha Nikaya 1); Rahula, What the Buddha Taught

Not only physical: the texts describe many planes of existence, seen and unseen, and treat the mind as primary — «mind precedes all things.» Yet there is no eternal spiritual substance anywhere; every realm and every state of mind is impermanent and conditioned.

SOURCES: Dhammapada 1–2; Gethin, The Foundations of Buddhism

There is consciousness beyond any one body, but no soul: the doctrine of anatta (non-self) denies a permanent, unchanging self. What continues — within a life and across lives — is a causally connected stream of mental events, not a fixed «me.»

SOURCES: Anatta-lakkhana Sutta (Samyutta Nikaya 22.59); Milinda Panha

Consciousness (vinnana) is one of the five processes that make up a person: a flow of moments of awareness, each arising from conditions — a sense meets an object, and knowing occurs. The Buddha rebuked a monk who took consciousness to be a single thing that wanders through lives unchanged.

SOURCES: Mahatanhasankhaya Sutta (Majjhima Nikaya 38); Rahula, What the Buddha Taught

Strictly, nothing does — «the same person» is a useful label pinned on an unbroken causal stream, the way a flame at midnight is neither the same flame as at dusk nor a different one. The classic dialogue of King Milinda and the monk Nagasena works through exactly this puzzle.

SOURCES: Milinda Panha; Anatta-lakkhana Sutta (Samyutta Nikaya 22.59)

Neither sinful nor divine: beings arrive carrying karmic dispositions, wholesome and unwholesome, from past lives. One early text calls the mind «luminous» but stained by visiting defilements; the Mahayana develops this into buddha-nature — the capacity of every being to awaken.

SOURCES: Anguttara Nikaya 1.49–52; Williams, Mahayana Buddhism

Both: karma conditions the situation you are born into, but it does not dictate your choices — the Buddha explicitly rejected the fatalist teachers of his day. Intention is the heart of action («intention, monks, is what I call karma»), so effort and training are real and decisive.

SOURCES: Nibbedhika Sutta (Anguttara Nikaya 6.63); Titthayatana Sutta (Anguttara Nikaya 3.61)

Mind and body (nama-rupa) arise together and depend on each other, like two sheaves of reeds propped one against the other — neither stands alone, and the texts reduce neither to the other. Meditation works on both at once: posture and breath steady the mind, and the mind's states show in the body.

SOURCES: Nalakalapiyo Sutta (Samyutta Nikaya 12.67); Gethin, The Foundations of Buddhism

The question is deliberately set aside: the Buddha said the beginning of the round of existence «is not to be discerned,» and he declined metaphysical puzzles that do not help end suffering — comparing the questioner to a man shot with an arrow who demands the archer's biography before treatment.

SOURCES: Samyutta Nikaya 15.3; Cula-Malunkya Sutta (Majjhima Nikaya 63)

There is no creation story: Buddhist cosmology describes universes expanding and contracting through immense cycles, with no first moment that can be found. One discourse describes a world re-forming after a long contraction — partly as satire of the claim that a creator god started it.

SOURCES: Agganna Sutta (Digha Nikaya 27); Samyutta Nikaya 15.3

The root of the act: deeds driven by greed, hatred, or delusion are unwholesome; deeds driven by generosity, love, or wisdom are wholesome. The practical test the Buddha gave his own son: before, during, and after acting, ask whether the act harms yourself, others, or both.

SOURCES: Ambalatthika-Rahulovada Sutta (Majjhima Nikaya 61); Nibbedhika Sutta (Anguttara Nikaya 6.63)

Lovingkindness, compassion, joy in others' good, and equanimity — the four «divine abidings» — along with generosity, patience, truthfulness, mindfulness, and wisdom. The Metta Sutta asks the practitioner to cherish all beings as a mother protects her only child.

SOURCES: Metta Sutta (Sutta Nipata 1.8); Rahula, What the Buddha Taught

For everyone, the Five Precepts: no killing, no stealing, no sexual misconduct, no false speech, no intoxicants. Monks and nuns take on hundreds more rules; «right livelihood» also rules out trading in weapons, living beings, meat, intoxicants, and poison.

SOURCES: Sigalovada Sutta (Digha Nikaya 31); Vanijja Sutta (Anguttara Nikaya 5.177)

Meditation and mindfulness; chanting and recollection of the Buddha, the Dhamma, and the Sangha; keeping the precepts; giving food to monks and other merit-making; observance days (uposatha) and festivals such as Vesak. For monastics, a full daily rule of practice and study.

SOURCES: Gethin, The Foundations of Buddhism; Rahula, What the Buddha Taught

The Sigalovada Sutta lays out mutual duties — parents and children, husband and wife, friends, teachers, employers and workers — and is often called the lay person's code. Hardship is met with the understanding of impermanence and with equanimity, not resignation; community is sustained by generosity and the temple.

SOURCES: Sigalovada Sutta (Digha Nikaya 31); Gethin, The Foundations of Buddhism

In the Theravada, the arahant: one who has extinguished greed, hatred, and delusion and lives in unshakable peace. In the Mahayana, the bodhisattva: one who vows, out of compassion, to keep returning until every being is free.

SOURCES: Dhammapada 90–99 (the arahant); Shantideva, Bodhicaryavatara

Karma and correction, not divine punishment or forgiveness: an act, once done, ripens — but a life filled with great goodness dilutes past wrong, as a spoonful of salt vanishes in a river though it ruins a cup of water. Monastics formally confess breaches; for everyone, the response is acknowledgment, resolve, and renewed practice.

SOURCES: Lonaphala Sutta (Anguttara Nikaya 3.99); Vinaya Pitaka (patimokkha confession)

To awaken: to end craving and ignorance, and so end suffering — for oneself in the Theravada framing, for all beings in the Mahayana. Meaning is found in walking the path itself: a life of ethics, meditation, and growing wisdom.

SOURCES: Dhammacakkappavattana Sutta (Samyutta Nikaya 56.11); Rahula, What the Buddha Taught

Rebirth: the stream of consciousness continues into a new life — human, animal, ghostly, hellish, or divine — according to karma, with no soul carried over. For the fully awakened there is no further rebirth; what nirvana after death is like, the Buddha refused to describe, saying the categories no longer apply — like asking where a fire goes when it goes out.

SOURCES: Aggi-Vacchagotta Sutta (Majjhima Nikaya 72); Samyutta Nikaya 15.3

Liberation: nirvana, the complete and final end of suffering, described as the highest happiness — attainable in this life, not only after death.

SOURCES: Dhammapada 203–204; Rahula, What the Buddha Taught

For each being, nirvana is the final destination — though reaching it may take countless lives. For humanity as a whole there is no promised end-state: world-cycles continue without a final act, though the Mahayana teaches that every being carries the capacity to awaken and, on many readings, eventually will.

SOURCES: Gethin, The Foundations of Buddhism; Williams, Mahayana Buddhism

Repeating cycles, ended one being at a time: there is no last judgment and no judge — karma operates as law, not verdict. Nirvana is called the end of the self only loosely: the texts say no self ever existed to be destroyed; what ends is craving and the round of rebirth.

SOURCES: Aggi-Vacchagotta Sutta (Majjhima Nikaya 72); Anatta-lakkhana Sutta (Samyutta Nikaya 22.59)

As a rhythm of calm and community: meditation and chanting, temple visits, merit-making, festivals such as Vesak, and the quiet prestige of the monk's alms bowl at dawn. Emotionally it ranges from Zen austerity to Pure Land devotion and the ritual color of Tibet.

SOURCES: Gethin, The Foundations of Buddhism

Three great streams: Theravada («the way of the elders») in Sri Lanka and Southeast Asia; Mahayana («the great vehicle») across East Asia, including Zen and Pure Land; and Vajrayana, the tantric Buddhism of Tibet and Mongolia.

SOURCES: Gethin, The Foundations of Buddhism

Deeply: Buddhism has everywhere blended with what it found — spirit shrines in Thailand and Myanmar, Confucian and Daoist thought in China, Shinto in Japan, the Bon tradition in Tibet. In the modern West it often arrives stripped down to meditation and psychology.

SOURCES: Gethin, The Foundations of Buddhism; D. Lopez, Buddhism and Science

Whether the Mahayana sutras are the Buddha's word; how essential rebirth and the unseen realms are (secular Buddhists set them aside, traditionalists object); whether full ordination for women should be restored in Theravada lands; and how far monks should engage in politics.

SOURCES: Williams, Mahayana Buddhism; S. Batchelor, Buddhism Without Beliefs

The charge of pessimism rests on misunderstanding — the texts claim to diagnose suffering and to cure it, and Rahula's classic reply is that Buddhism is neither pessimistic nor optimistic but realistic. Real disagreements remain: whether karma and rebirth are true, whether non-self is coherent, and whether detachment undervalues love and grief.

SOURCES: Rahula, What the Buddha Taught; E. Thompson, Why I Am Not a Buddhist

Identity begins with taking refuge in the Buddha, the Dhamma, and the Sangha, and with the precepts. The exchange of alms for teaching binds laity and monastics into one moral economy, and the temple anchors education, festivals, and rites of passage across Buddhist Asia.

SOURCES: Gethin, The Foundations of Buddhism

Often comfortably: with no creation account to defend, many Buddhists see science as a partner, and the Dalai Lama has written that if science disproves a Buddhist claim, the claim should yield. The friction points are rebirth, karma, and the unseen realms — held literally by traditionalists, read symbolically or shelved by modernists.

SOURCES: Dalai Lama, The Universe in a Single Atom; Lopez, Buddhism and Science

No political blueprint is given: the Vinaya governs monastic life, while lay society is guided by the precepts and by ideals like the righteous «wheel-turning monarch» who rules by Dhamma rather than force. Historically, sangha and kings lived in mutual support — kings protected the order, monks lent moral legitimacy — while law itself remained the ruler's affair.

SOURCES: Cakkavatti-Sihanada Sutta (Digha Nikaya 26); Agganna Sutta (Digha Nikaya 27)

By Dhamma rather than by institutions: the tradition lists ten royal virtues — among them generosity, morality, non-anger, non-violence, and patience — and holds that an unrighteous king brings ruin on his realm. There is no doctrine of rebellion; the classic instruments are moral counsel and withheld legitimacy, as when Burmese monks overturned their alms bowls against the junta in 2007.

SOURCES: Dasavidha-rajadhamma (Jataka); Rahula, What the Buddha Taught

Both can awaken fully — the Buddha said so, and the Therigatha preserves enlightenment poems by the first nuns. Yet the texts say he founded the nuns' order reluctantly and bound it by extra rules subordinating nuns to monks; full ordination for women later lapsed in Theravada lands, and its modern revival remains contested. In lay life, duties run both ways — including the respect and faithfulness a husband owes his wife.

SOURCES: Cullavagga X; Therigatha; Sigalovada Sutta (Digha Nikaya 31)

Peaceful coexistence is the norm and the record is largely tolerant: no conversion by force is taught, and when the householder Upali converted, the Buddha told him to keep supporting his former Jain teachers. Ashoka's edicts command honoring all sects. The modern exceptions are real: Buddhist-nationalist movements in Myanmar and Sri Lanka have turned against religious minorities.

SOURCES: Upali Sutta (Majjhima Nikaya 56); Edicts of Ashoka; S. Tambiah, Buddhism Betrayed?

The canon gives no just-war doctrine: the first precept forbids killing, violence is forbidden to monks absolutely, and the Dhammapada teaches that hatred is never stilled by hatred. In practice Buddhist kingdoms waged war, the Sri Lankan chronicle Mahavamsa notoriously excuses a king's war against non-Buddhists, and some Zen institutions backed Japanese militarism — episodes the tradition's own scholars condemn as betrayals of the precept.

SOURCES: Dhammapada 5; Mahavamsa; B. Victoria, Zen at War

Freely: there is no apostasy penalty and no doctrine of punishing those who leave. A monk may disrobe and return to lay life without disgrace in most Theravada cultures — in Thailand temporary ordination is even customary — and lay people drift in and out with, at most, family or social disappointment.

SOURCES: Vinaya Pitaka; Gethin, The Foundations of Buddhism

Its epistemology: the Kalama Sutta invites inquirers to test the teaching against their own experience rather than accept it on authority — a stance admired even by critics. Its psychology of craving and suffering strikes many as simply accurate, and its core practices show measurable effects: mindfulness programs built on Buddhist meditation are used clinically for stress, pain, and relapsing depression. And it asks for no belief in a creator, so its central claims can be tried before being trusted.

SOURCES: Kalama Sutta (Anguttara Nikaya 3.65); J. Kabat-Zinn, Full Catastrophe Living; Rahula, What the Buddha Taught

The oldest objection is internal: if there is no self, what is reborn, and who benefits from moral effort? The classical answer — continuity without identity, one flame lighting another — was worked out in the Milinda Panha and refined for centuries. The sharpest modern critique is Evan Thompson's Why I Am Not a Buddhist, which argues that «Buddhist exceptionalism» overstates the scientific standing of Buddhist claims. The tradition's best reply concedes that the science is young and returns to its own ground: the core claims are offered for testing in practice, not as settled findings.

SOURCES: Milinda Panha; Thompson, Why I Am Not a Buddhist

Mostly — at the price of great subtlety: rebirth without a self, moral consequences without a fixed agent, and nirvana as neither existence nor non-existence all require the tradition's careful distinctions, such as the «two truths» of conventional and ultimate reality. Buddhist philosophers spent two millennia sharpening these answers; critics reply that the puzzles are managed rather than dissolved. Both the sophistication of the answers and the persistence of the debate are part of the record.

SOURCES: Nagarjuna, Mulamadhyamakakarika; Milinda Panha; Thompson, Why I Am Not a Buddhist

In psychology, remarkably well: impermanence, the link between craving and distress, and the trainability of attention fit everyday experience and clinical research. In history, the broad account of its spread is well documented. The traditional cosmology — rebirth realms, world-cycles, karmic causation across lives — is not confirmed by science; traditionalists hold it literally, modernists read it symbolically or suspend judgment.

SOURCES: Kabat-Zinn, Full Catastrophe Living; Lopez, Buddhism and Science

The full path is livable — but it was designed for renunciants, and only a small minority ever live it whole. Lay Buddhists everywhere blend it with local religion, family ambition, and modern economics; merit-making largely replaces meditation. Critics add that strict non-attachment sits awkwardly with married love and grief; the tradition answers that love without clinging is love perfected, and that the Sigalovada Sutta provisions family life fully.

SOURCES: Sigalovada Sutta (Digha Nikaya 31); Gethin, The Foundations of Buddhism

Achievements: great monastic universities such as Nalanda, the meditation traditions, a vast art and literature, and the world's oldest dated printed book (a Diamond Sutra of 868 CE); its spread across Asia was largely without conquest. Harms in its name: warrior-monk armies in medieval Japan, Zen institutional support for Japanese militarism through World War II, and Buddhist-nationalist violence in Myanmar — including against the Rohingya — and in Sri Lanka. Buddhist leaders and scholars answer plainly that these violate the first precept; critics note the tradition produced no doctrine strong enough to prevent them.

SOURCES: Victoria, Zen at War; Tambiah, Buddhism Betrayed?; Gethin, The Foundations of Buddhism

The tradition names its own test: the Kalama Sutta and the «come and see» formula stake the teaching on results, so a fair person could walk away if sustained, well-guided practice failed to reduce craving and suffering — that core is genuinely testable. Karma and rebirth are harder: the canon says only awakened vision confirms them, which places them beyond ordinary checking, and modernists like Stephen Batchelor therefore bracket them as inherited metaphysics. Evidence that mind is wholly dependent on the brain would strike at rebirth directly; traditionalists reply that no such proof exists, and that the practice stands either way.
