Can you tell me about the author of Shri Sai Satcharita and the reliability of the stories within it?

The Shri Sai Satcharita was written by Annasaheb, who undertook the work by the command of Shri Samarth Sadguru Sai Baba Maharaj himself. According to Chapter 0, the reliability of the stories, or Leelas, described in the text is quite high. Many of the events were witnessed by Annasaheb with his own eyes. For the other accounts, the experiences were communicated to him directly by devotees, many of whom were still living when the book was composed. Annasaheb's role, as described in Chapter 0, was to take these true experiences and dress them "in a poetic, attractive, and beautiful garment with his graceful and succulent voice," ensuring the accounts were both authentic and engaging.
