What is a question about this article? If the question is unanswerable, say "unanswerable".

According to author Michael Carrithers, while there are good reasons to doubt the traditional account, "the outline of the life must be true: birth, maturity, renunciation, search, awakening and liberation, teaching, death." In writing her biography of the Buddha, Karen Armstrong noted, "It is obviously difficult, therefore, to write a biography of the Buddha that meets modern criteria, because we have very little information that can be considered historically sound... [but] we can be reasonably confident Siddhatta Gotama did indeed exist and that his disciples preserved the memory of his life and teachings as well as they could."[dubious – discuss]
