What are the recommended practices for building a community around Sai Baba's life story, according to the preface?

The preface found in Chapter 0 suggests that a powerful way to build a community is through the collective study and devotional reading of a detailed biography. Specifically, it highlights the practice of performing Parayan or Saptah (a week-long reading) of a Guru's life story. It notes that while some works exist, they are often not comprehensive enough for this purpose. As Chapter 0 explains, by studying and performing Parayans of a detailed poetic biography like the Shri Sai Satcharita, devotees not only perform Guru service but also engage in a form of public service that helps others achieve the purpose of their lives, thereby fostering a strong spiritual community.
