The original version of the Dhammapada is in the Khuddaka Nikaya, a division of the Pali Canon of Theravada Buddhism.The Buddhist scholar and commentator Buddhaghosa explains that each saying recorded in the collection was made on a different occasion in response to a unique situation that had arisen in the life of the Buddha and his monastic community. His commentary, the Dhammapada Atthakatha, presents the details of these events and is a rich source of legend for the life and times of the Buddha.
