I'm a devotee of Sai Baba. What specific text is recommended for performing Parayans and Saptahs, and who wrote it?

For devotees of Shri Sai Baba, the preface explicitly recommends the "Shri Sai Satcharita" as the ideal work for performing Parayans (devotional readings) and Saptahs (week-long readings). This biography is described as a sweet, inspirational, and grace-filled work written by the late devotee Shri Govind Raghunath, who was also known as Annasaheb Dabholkar. As noted in chapter 0, this text was originally published chapter by chapter in the Shri Sai Leela magazine. It is highlighted as one of only two ancient, detailed, and comprehensive Guru biographies in Maharashtra suitable for these intensive devotional practices, making it the principal text for the community of Sai Baba's followers.
