What does Chapter 50 reveal about the nature of Sai and the authorship of the Shri Sai Satcharitra?

Chapter 50 portrays Sai as a pure embodiment of consciousness, describing him as the "Unmanifest itself has taken form." He is depicted as desireless yet deeply compassionate towards his faithful devotees. The chapter profoundly addresses the authorship of the book, suggesting it is not a mere human creation. The author expresses his own inadequacy, stating, "What power do I, a wretched one, have to describe his glory?" It is then revealed that Sai himself, "out of love for his devotees, reveals this book through grace." This positions the Shri Sai Satcharitra as a divine work channeled through the author by Sai's will.
