I'm looking for the part of the book that connects Chandbhai Patil with Gajanan Maharaj. Can you summarize it?

Based on the provided source chunks, there is no connection mentioned between Chandbhai Patil and Gajanan Maharaj. The text from Chapter 0 details Chandbhai Patil's encounter with a different holy man, referred to only as "Maharaj." This Maharaj helped Chandbhai find his lost horse and later stayed at his home. It was with Chandbhai's family's wedding procession that this Maharaj traveled to Shirdi. As Chapter 0 explains, this same Maharaj was later named Sai Baba by Mhalasapati, and the text makes no mention of Gajanan Maharaj at all.
