The historical figure
The biographical record is thin and the dates are contested. The traditional Theravāda dating placed his birth at 563 BCE and his parinirvāṇa at 483 BCE; current Indological scholarship has shifted the conventional reckoning later, to a birth somewhere between 490 and 480 BCE and a death around 410–400 BCE. What is uncontested in the early canon: he was born Siddhārtha Gautama into the ruling family of the Śākya clan in what is now the Nepal–India border region; he was raised in the palace at Kapilavastu until his late twenties; he left family and rank to take up the renunciate's life; he spent six years pursuing the ascetic curriculum of the śramaṇa movement of his time and abandoned its extremes; and he awakened, the canon records, under a pīpal tree near the village of Gayā during the night of a full moon. The forty-five years of teaching life that followed crossed Magadha, Kośala and the surrounding kingdoms on foot, with the seasonal monsoon periods spent in fixed retreat at a small set of monastic settlements donated by lay patrons. The canon is concrete about who he taught — kings, householders, courtesans, the ascetic communities of his peers — and concrete about how the teaching travelled, person to person, in the oral register of the Indo-Aryan languages of the Gangetic plain.
What he taught
The teaching the canon preserves is doctrinally compressed and operationally exact. The first sermon at the Deer Park in Sarnath laid out the Four Noble Truths as a clinical four-part diagnosis: dukkha — unsatisfactoriness — is the structural feature of conditioned experience; it has a cause, the compounding of craving and aversion onto bare contact; it can end, and its ending is nirvāṇa; and the way to its ending is a graded path, the Noble Eightfold Path of right view, intention, speech, action, livelihood, effort, mindfulness and concentration. The architecture is medical rather than metaphysical. Around this core the early canon records the three marks — impermanence, unsatisfactoriness, and not-self — as the recurring characteristics of all conditioned phenomena, and dependent origination as the twelve-link account of how the structure of suffering perpetuates itself across a stream of moments. The Buddha was, by the canon's own emphasis, a teacher of method rather than of doctrine. The famous parable of the raft makes the point explicitly: the teaching is the boat one builds to cross the river; one does not carry it on one's back once the other shore is reached. The same restraint governs the canonical response to the metaphysical questions of his contemporaries — the fourteen undeclared questions about the eternity of the cosmos, the relation of mind to body, what happens to a tathāgata after death. The canon records him as refusing to take a position on each, on the grounds that none was relevant to the operative work of ending suffering.
In the index
The Buddha himself is not a row in the index — the figure pre-dates audio-visual record by twenty-four centuries — but the teaching reaches the corpus through several lineages of contemporary transmission. Jon Kabat-Zinn's MBSR course is the secularised entry point, presenting the ānāpānasati and satipaṭṭhāna instructions of the early canon stripped of doctrinal scaffolding and delivered in an eight-week clinical format. Tara Brach and Jack Kornfield's *Power of Awareness*, descending from the Insight Meditation Society's reconstitution of the vipassanā curriculum, presents the same instructions inside the Theravāda frame the Buddha himself worked in, with the Four Truths named explicitly. Joseph Goldstein and Sharon Salzberg's *Insight Meditation* course carries the same lineage in its longer-form practice register. From the Mahāyāna side, Thich Nhat Hanh on emptiness, signlessness and aimlessness reframes the third Truth against the three dharma seals the Lotus-tradition extracted from the same canonical material, and Br. Troi Duc Niem's reflection from Plum Village carries the engaged Buddhism extension of the bodhisattva vow into a contemporary monastic register. Pema Chödrön's *When Things Fall Apart* and her course on awakening compassion carry the Vajrayāna inheritance through the Karma Kagyü lineage of her teacher Chögyam Trungpa — in Trungpa's own *Cutting Through Spiritual Materialism* the same teaching is delivered with less institutional cushioning. Across the three vehicles the operative content is the Buddha's: the diagnosis is medical, the practice is mindful contact with experience, the goal is the dropping of the compounding moves that turn bare experience into protracted suffering.
What he isn't
The Buddha is not a god in the canonical reading, even where popular Buddhism has treated him as one. He is not the founder of a revealed religion: the dharma he taught is, in the early canon's own claim, the structure of how things are, discoverable in principle by any sustained investigation. He is not the only such figure — the early texts name previous buddhas in a long backwards chain and a future Maitreya still to come, and the title buddha is a class noun before it is a proper one. He is not the source of doctrinal authority in the way later traditions sometimes claim: his own instruction to the Kālāmas in Aṅguttara Nikāya 3.65 is the canonical warrant for testing every teaching against direct experience rather than against received authority, including his own. And he is not, finally, a figure of devotional surrender in the sense the Hindu bhakti traditions later develop — the early canon is consistent that veneration of the teacher is appropriate, attachment to the teacher is not, and the triratna the practitioner takes refuge in is the Buddha, the dharma and the sangha as a single triadic instrument rather than the figure alone.
