The Pali Canon is the standard scripture collection of the Theravada Buddhist tradition. It was not printed until the nineteenth century, but is now available in electronic form. However, the English translation, by the Pali Text Society, is not yet complete. The Canon was written down from oral tradition in the last century B.C.E. Most scholars give it some sort of pre-eminence among sources for early Buddhism. It is composed in the Pali language, and falls into three general categories, called pitaka (piṭaka, basket) in Pali. Because of this, the canon is traditionally known as the tipitaka (tipiṭaka; three baskets). The three pitakas are as follows.
1. Vinaya Pitaka, dealing with rules for monks and nuns.
2. Sutta Pitaka, discourses, most ascribed to the Buddha, but some to disciples.
3. Abhidhamma Pitaka, variously described as philosophy, psychology, metaphysics, and so on.
According to the scriptures a council was held shortly after the Buddha's death to collect and preserve his teachings. It is traditionally believed by Theravadins that most of the Pali Canon was recited orally from this time, with only a few later additions. There are wide differences of opinion among scholars as to what extent the teachings may be traced to the historical Buddha himself.
