In this second talk in a lecture series on the Great Disciples, the speaker, Thanissaro Bhikkhu, talks about the contributions by Ananda to the Dharma. Because of his incredible memory, what we know in the Pali Canon today came mostly from Ananda's recollection of the Buddha's teachings. He described in detail who came to the Buddha, what were their question/problem, and how the Buddha addressed that particular question/problem. This is an important contribution to our understanding of how the Dharma was taught, because so much of it depended on who was asking what, and what kind of teaching was the best for them. Another debt that we owe Ananda is that he asked the Buddha questions that no one had asked. And Ananda's questions in turn sparked the Buddha to explain things or do things that he otherwise might not have explained or done.
