Explanation:

The Tripitaka was composed between about 550 BCE and about the start of the common era, likely written down for the first time in the 1st century BCE. The Dipavamsa states that during the reign of Valagamba of Anuradhapura (29–17 BCE) the monks who had previously remembered the Tripitaka and its commentary orally now wrote them down in books, because of the threat posed by famine and war. The Mahavamsa also refers briefly to the writing down of the canon and the commentaries at this time. Each Buddhist sub-tradition had its own Tripitaka for its monasteries, written by its sangha, each set consisting of 32 books, in three parts or baskets of teachings: Vinaya Pitaka (“Basket of Discipline”), Sutta Pitaka (“Basket of Discourse”), and Abhidharma Pitaka (“Basket of Special Doctrine”).
