The Sutta Pitaka, a collection of discourses, is primarily composed of dialogues between the Buddha and other people. It consists of five groups of texts: Digha Nikaya (collection of long discourses), Majjhima Nikaya (collection of medium length discourses), Samyutta Nikiya (collection of grouped discourses), Anguttara Nikaya (collection of discourses on numbered topics), and Khuddaka Nikaya (collection of miscellaneous texts). In the fifth group, the jatakas, comprising stories of former lives of the Buddha, and the Dhammapada (religious sentences), a summary of the Buddha’s teachings on mental discipline and morality, are especially popular.
