How can devotees serve Sai Baba and build a community through books and study?

Based on the teachings in Chapter 0, a Sadguru accepts service from devotees through books in two main ways. One is by having his biographies written by devotees, and the other is by accepting service in the form of study and Parayans from the writer and the congregation. By studying and performing Parayans of a detailed poetic Guru biography, devotees perform a direct Guru service. This shared practice also allows the writer to gain the merit of serving God in humanity, and the participating devotees can achieve the purpose of their lives, thus fostering a strong community.
