Can you tell me about Madhavrao Balwant Deshpande and how his relationship with Sai Baba developed?

Madhavrao Balwant Deshpande, also known as Shama, was a schoolmaster in a Marathi school located in a small house adjacent to the Masjid's courtyard. According to Chapter 0, he began visiting Maharaj more frequently than others, partly due to the proximity of his school. He would go to the Masjid, fill the chillum, and smoke with Maharaj. This regular contact allowed a close bond to form, and Maharaj started to attract Madhavrao's mind. Over some years, this relationship deepened to the point where Madhavrao left all other businesses to dedicate his life to serving Maharaj and the devotees who came for darshan, becoming a key advisor and support for many.
