Are there specific texts recommended for performing a Parayan of Sai Baba's life, and why are they considered suitable?

Yes, for those wishing to perform a Parayan specifically for Sai Baba, the text titled "Shri Sai Satcharita" is highly recommended. As explained in Chapter 0, this sweet, inspirational, and grace-filled biography was written by the late devotee Shri Govind Raghunath alias Annasaheb Dabholkar. Unlike other works where a saint's biography might only span a few pages, the "Shri Sai Satcharita" is a comprehensive and detailed work, making it perfectly suitable for Parayans and Saptahs. It is considered one of only two such detailed Guru biographies found in Maharashtra.
