What role did Madhavrao (Shama) play in the interactions between devotees and Sai Baba, particularly concerning the offering of books?

Madhavrao, also known as Shama, often acted as a crucial intermediary for devotees wishing to approach Sai Baba. As Chapter 27 details, devotees who wanted to offer books to Baba for his blessing would often take Madhavrao along with them. They would have him present the book at an opportune moment, as it required patience to navigate Baba's moods. Furthermore, Shama became the designated keeper of many of these sacred texts. Baba would frequently take a book from a devotee and, instead of returning it, would hand it to Shama with instructions to add it to his records, making him the custodian of a holy library for future disciples.
