Why is 'Shri Sai Satcharita' considered a foundational text for community activities like Parayans, as opposed to other works?

The 'Shri Sai Satcharita' is considered foundational because it is a detailed, comprehensive, and grace-filled biography suitable for Parayans and Saptahs. Chapter 0 contrasts this with other works, such as those by Shri Dasganu Maharaj, which, while valuable, are not comprehensive enough for a Parayan focused on a single saint, often covering a biography in just a few pages. The 'Shri Sai Satcharita', written by Annasaheb Dabholkar, is presented as one of only two such detailed Guru biographies in Maharashtra, making it uniquely qualified for in-depth community study and devotion.
