Besides the Shri Sai Satcharita, are there other detailed biographies of Sai Baba that are considered suitable for community Saptahs?

Based on the information provided, there are no other works about Sai Baba as detailed as the Shri Sai Satcharita that are recommended for Parayans. Chapter 0 explicitly states that for performing a Parayan of a single saint's biography, many existing works are not comprehensive enough. It then highlights two major exceptions in Maharashtra suitable for such detailed study: the Guru Charitra and the Shri Sai Satcharita. The text firmly concludes by stating, 'Apart from these two Guru biographies, no third work written in such detail is found,' which reinforces the unique and central position of the Shri Sai Satcharita for community study of Sai Baba.
