How were the stories and leelas for the Shri Sai Satcharita collected and authenticated?

The authenticity of the stories in the Shri Sai Satcharita is a key point discussed in the source. Chapter 0 clarifies that the author, Annasaheb, was not simply retelling myths. Many of the leelas and events described in the book were things he had witnessed with his own eyes. For the stories he did not personally witness, the information was gathered directly from devotees who had the experiences, either in their waking life or in dreams. These devotees communicated their experiences to Annasaheb, and it's noted that many of them were still alive at the time of writing, serving as living testaments to the events chronicled.
