Can you provide details about the author and publication of the Shri Sai Satcharita as described in the preface?

Certainly. The preface, as cited in Chapter 0, describes the Shri Sai Satcharita as a 'recent, sweet, inspirational, and grace-filled biography' about the 'modern crown jewel of saints, Shri Sachidanand Samarth Sadguru Sai Baba Maharaj.' The author is identified as the late devotee Shri Govind Raghunath, who was also known as Annasaheb Dabholkar. A unique detail about its creation, mentioned in Chapter 0, is that the work was not published all at once. Instead, it was released chapter by chapter over a span of six years in the 'Shri Sai Leela' magazine, and had only recently been completed with a final chapter at the time the preface was written.
