Avadāna literature is a category of Buddhist religious texts that consists of narrative stories illustrating the results of karma and the workings of moral causation. These stories are often meant to inspire virtuous conduct and faith in the Buddha’s teachings.
The stories typically describe deeds done in past lives by individuals who later attained Buddhahood or other significant spiritual status.
The Avadānas are found in both Theravāda and Mahāyāna traditions.
Famous collections include the "Divyāvadāna" and "Mahāvastu.”
