How does the tradition of creating and studying Guru biographies, such as the Shri Sai Satcharita, facilitate a Sadguru's service from devotees?

The provided text from Chapter 0 explains that a Sadguru accepts service from devotees through books in two ways. The second method, which is highly relevant here, is by having his biographies written by devotees. These biographies are then used for study and Parayans by both the writer and the broader congregation of devotees. Works like the Shri Sai Satcharita, described as a detailed, comprehensive, and grace-filled biography, become the primary vehicle for this form of service. By collectively engaging with this text, the community of devotees offers accepted service to the Guru and strengthens their shared spiritual path.
