How does the creation and study of literature like the Shri Sai Satcharita contribute to a saint's legacy and community?

As explained in Chapter 0, a Sadguru accepts service through books in two ways: by writing great works themselves, or by having their biographies written by devotees. The Shri Sai Satcharita is an example of the latter, where a devotee, Annasaheb Dabholkar, created a detailed and inspirational work. This act of creation is a service, and the subsequent study and Parayans performed by the congregation of devotees is also a form of service. This process creates a lasting literary legacy and a communal focal point that helps devotees achieve their life's purpose and solidifies the community around the saint's life story.
