How does a Sadguru accept service from devotees through books, and what are the different forms this service can take?

As detailed in Chapter 0, a Sadguru accepts service from devotees through books in two primary ways. The first method is when the Sadguru themselves authors great spiritual works, such as the cited examples of Shri Dnyaneshwari or Shri Dasbodh. The second method involves the Sadguru having their biographies written by their devotees. In this latter case, the service is accepted not only from the writer but also from the congregation of devotees who engage in the study and devotional reading (Parayans) of the biography. This creates a communal form of service that benefits both the author and the readers, helping them achieve the purpose of their lives.
