How can devotees foster a community and serve their Sadguru through literary works?

According to the preface in Chapter 0, a Sadguru accepts service from devotees through books in two main ways. One is by having their biographies written by devoted followers. By studying and performing Parayans (devotional readings) of these detailed poetic biographies, both the writer and the larger community of devotees engage in Guru service. The author gains the merit of serving God in humanity (Jan-Janardan), and the other devotees who study the work are helped to achieve the purpose of their lives. This shared practice of studying a central text like the Shri Sai Satcharita is a powerful way to build and sustain a community around the Guru's life and teachings.
