What are some prescribed methods for collectively studying the life of a Guru like Sai Baba to foster a sense of community?

Chapter 0 describes a powerful method for collective study, which involves performing Parayan or Saptah (a week-long devotional reading) of a Guru's biography. While some works by poets like Shri Dasganu Maharaj exist, they are often too brief for this purpose. The text emphasizes that studying a detailed, poetic Guru biography is a form of Guru service. When a congregation of devotees engages in Parayans, they not only serve the Guru but also help each other achieve their life's purpose, thereby strengthening the community bond through shared spiritual practice.
