In a public talk given in London, on the occasion of Wesak in May 1999, Sangharakshita addresses a subject that he has not spoken about at length before, that of gratitude.Using, as his starting point, the Buddha’s Enlightenment under the Bodhi Tree, he explores the idea of gratitude as an important quality for the Buddhist to develop. In doing so he considers the three traditional recipients of gratitude, namely parents, teachers and spiritual friends, and then concludes by listing four possible reasons for ingratitude.
