What role did Madhavrao, also known as Shama, play when devotees wanted to have their books blessed by Sai Baba?

According to Chapter 27, Madhavrao, or Shama, played a crucial intermediary role for devotees wishing to have their books blessed by Sai Baba. The text states that approaching Baba required patience, so devotees would often take Madhavrao along and place him in front to present the book at an appropriate time. Furthermore, Baba often chose to give the blessed books to Shama for safekeeping, even when the original owners were eagerly waiting with outstretched hands. Baba would tell Shama, 'keep this copy; let it stay with you for now,' thereby entrusting him with building a collection of sacred texts.
