Can you tell me about the author and publication history of the Shri Sai Satcharita as mentioned in the preface?

Certainly. According to Chapter 0, the Shri Sai Satcharita is described as a recent, sweet, inspirational, and grace-filled biography of the modern saint, Shri Sachidanand Samarth Sadguru Sai Baba Maharaj of Shirdi. The author is identified as the late devotee Shri Govind Raghunath, who was also known by the name Annasaheb Dabholkar. A unique aspect of its creation, highlighted in the text, is that the work was not published all at once. Instead, it was released chapter by chapter over a period of six years within the pages of the Shri Sai Leela magazine before being completed.
