What are Parayans and Saptahs, and how do they relate to serving a Guru like Sai Baba?

According to the guidance in Chapter 0, performing a Parayan or a Saptah is a form of devotional service. It involves the dedicated study and reading of a Guru's biography, often over a set period. The text notes that the Sadguru accepts this service from the writer and the congregation of devotees. For followers of Sai Baba, the Shri Sai Satcharita by Annasaheb Dabholkar is identified as a comprehensive work specifically suitable for such Parayans. This practice allows devotees to achieve the purpose of their lives and helps the writer gain merit.
