Could you describe the origin and authorship of the Shri Sai Satcharita as detailed in the preface?

The Shri Sai Satcharita is described as a recent, sweet, inspirational, and grace-filled biography of the modern crown jewel of saints, Shri Sachidanand Samarth Sadguru Sai Baba Maharaj. According to Chapter 0, it was written by the late devotee Shri Govind Raghunath, who was also known as Annasaheb Dabholkar. This significant work was not released all at once. Instead, it was published serially, chapter by chapter, over a period of six years within the pages of the Shri Sai Leela magazine before being completed with a concluding chapter.
