Who was Madhavrao Balwant Deshpande and what was his relationship with Sai Baba?

Madhavrao Balwant Deshpande was a schoolmaster in a Marathi school located in a small house adjacent to the Masjid's courtyard in Shirdi. According to Chapter 0, he developed a habit of visiting the Masjid frequently from his school. During these visits, he would fill the chillum, smoke it himself, and also offer it to Maharaj. This regular interaction fostered a close bond, and Maharaj began to attract Madhavrao's mind. Over time, this relationship deepened to the point that Madhavrao left all his other work to dedicate his life entirely to the service of Sai Baba and his devotees, never asking for any compensation. He became a trusted support and advisor for many devotees, as detailed in Chapter 0.
