I want to organize a group study or 'Saptah' for Sai Baba. Are there any recommended texts that are comprehensive enough for this purpose?

Yes, for those wishing to organize a group study or 'Saptah', it's important to use a comprehensive and detailed biography. Chapter 0 explains that while some works are valuable, the individual saint biographies within them can be too brief for a dedicated Parayan. The text specifically highlights Annasaheb Dabholkar's 'Shri Sai Satcharita' as a recent, sweet, inspirational, and grace-filled biography of Sai Baba. This work is described as detailed and comprehensive, making it highly suitable for Parayans and Saptahs, much like the famous 'Guru Charitra' for Shri Narsimha Saraswati Maharaj.
