Buddhist monks memorised their scriptures for centuries before anyone wrote them down
Theravada tradition holds that the Pali Canon was passed mouth to mouth for roughly four centuries, then inscribed on palm leaves in Sri Lanka around 29 BC. Memory still matters: a Burmese monk named Vicittasara learned the entire collection by heart for a modern council, a feat few people could imagine attempting.
The Pali Canon is Theravada Buddhism's standard scripture and the most complete early Buddhist canon to survive. It is split into three baskets, a name taken from the containers that once held palm-leaf manuscripts. The Vinaya covers monastic discipline, the Sutta holds sermons and discourses and is the largest, and the Abhidhamma offers systematic treatises, especially about the mind. The first two closely resemble texts of other early schools; the Abhidhamma is distinctively Theravadin.
Tradition says that three months after the Buddha's death, at a council in Rajgir, Ananda recited the discourses and Upali the rules, and monks kept them alive orally. The writing down is placed at the Alu Viharaya temple in Sri Lanka no earlier than 29 to 17 BC. Scholars note that oral reciters kept working alongside manuscripts for centuries, and that conservative monks probably resisted writing at first. The surviving Sri Lankan version was heavily edited in the 5th or 6th century CE, and the oldest physical fragments of canonical Pali come from the Pyu city-states of Burma in that era.
How much goes back to the Buddha himself is debated. Richard Gombrich argues that the core teachings are so coherent they must come from one mind. Peter Harvey agrees much derives from the Buddha but says some parts clearly came later, while adding that Theravadins seem not to have tampered with older material. The monks Sujato and Brahmali point to clues such as the absence of South Indian places and of any prophecy about Emperor Ashoka, suggesting early composition.
Language offers another twist. Theravadins long equated Pali with Magadhi, the tongue of the Buddha's region, but linguists find it closer to western Indian dialects, implying the teachings were shifted from an eastern language before Ashoka's time. Commentaries by Buddhaghosa in the 4th to 5th centuries shape traditional reading, summarised in his Visuddhimagga. In practice, lay Buddhists often recite short protective texts called Paritta, and Rupert Gethin suggests all of Buddhist history can be read as an unfolding of these early scriptures.
