The source mentions the Shri Sai Satcharita. How did this particular work contribute to building a community around Sai Baba's teachings?

The preface in Chapter 0 explains that the Shri Sai Satcharita, written by Annasaheb Dabholkar, is a sweet, inspirational, and grace-filled biography of Sai Baba. This detailed work is considered one of only two such comprehensive Guru biographies in Maharashtra suitable for Parayans and Saptahs. As Chapter 0 details, a Sadguru accepts service from devotees by having his biographies written for study and Parayans by the congregation. The Shri Sai Satcharita, published over six years, provided a foundational text for devotees to study collectively, which helps them achieve the purpose of their lives and builds a strong community around the Guru.
