What specific devotional practices involving texts are recommended for Sai Baba's followers to engage in together?

The text outlines the practice of performing a Parayan or Saptah, which involves a devotional reading of a saint's biography over a set period. Chapter 0 emphasizes that for this to be effective, the biography must be detailed and comprehensive. While some works by poets like Shri Dasganu Maharaj exist, they are not suitable for this purpose. Instead, the Shri Sai Satcharita is highlighted as the ideal text for Sai devotees. By studying and performing Parayans of such a detailed poetic biography, devotees engage in Guru service and also public service, as it brings the congregation of devotees together for a shared spiritual purpose.
