The traditional name of the Pāḷi Canon, Tipiṭaka, refers to the initial Three “baskets” that preserved and contained the handwriting script of the rules for the monastic and lay Buddhist practitioners (the first basket), of the records of the Buddha’s teaching (the second basket) and of the teaching’s interpretation (the third basket). The text also preserved the Buddha‘s knowledge about how the human mind functions. Thus today we have an authentic body of knowledge reaching back more than two thousand years. Theravāda Buddhism evolved in Sri Lanka thanks to the mission initiated by the Indian Ashoka Emperor (268–232 B. C.) and from there it spread across all of southern Asia (Cambodia, Laos, Myanmar, Thailand). Nowadays there is also a significant number of western practitioners and followers that identify with this branch of Buddhism in the USA, Canada, Australia and Europe.
