A classic entry in the Pali canon, this anthology charts the entire course of spiritual development as prescribed in the most ancient Buddhist texts. Drawing upon the Buddha's own words from Sutta Pitaka, they are arranged in accordance with two overlapping schemes of practice: the threefold training in virtue, concentration, and wisdom, and the seven stages of purification. A lengthy chapter on concentration provides sutta sources for all 40 classical subjects of meditation, while a chapter on wisdom cites texts relating to the development of insight.
