I want to organize a week-long reading (Saptah) for Sai Baba. What specific text is recommended in the source, and why is it considered suitable?

For those wishing to organize a Saptah, the text highly recommended is the Shri Sai Satcharita. As mentioned in Chapter 0, this work was written by the devotee Shri Govind Raghunath alias Annasaheb Dabholkar. It is described as a recent, sweet, inspirational, and grace-filled biography of Shri Sachidanand Samarth Sadguru Sai Baba Maharaj. It is considered particularly suitable for Parayans and Saptahs because, unlike other brief mentions in works by poets like Shri Dasganu Maharaj, it is a comprehensive and detailed poetic biography, which is a rare quality among such texts.
