What is the significance of performing a 'Parayan' or 'Saptah' of a Guru's biography, and how does this contribute to the community?

Performing a 'Parayan' or 'Saptah,' which is a devotional reading often conducted over a week, is a profound form of Guru service. According to Chapter 0, when devotees collectively engage in studying a detailed biography like the Shri Sai Satcharita, it creates a virtuous cycle. The writer of the biography is credited with performing Guru service, while the congregation of devotees who study the work also achieve the purpose of their lives. This shared spiritual activity helps build a strong community, as the writer gains the merit of serving God in humanity (Jan-Janardan), which fosters a sense of collective purpose and devotion among followers.
