Even though earlier works mentioning Sai Baba existed, why was the creation of the 'Shri Sai Satcharita' so important for his followers?

The creation of the Shri Sai Satcharita was crucial because earlier works, like those by Shri Dasganu Maharaj, were not comprehensive enough for a deep study of a single saint, often covering a biography in just two or three pages. Chapter 0 explains that for a community to properly engage in Parayans and Saptahs, a detailed, poetic, and comprehensive biography is necessary. The Shri Sai Satcharita, written by Annasaheb Dabholkar, filled this void by providing an inspirational and grace-filled account of Sai Baba's life, becoming one of only two such detailed Guru biographies found in Maharashtra, making it a cornerstone for communal study and devotion.
