Besides the Shri Sai Satcharita, are there other recommended works for Parayans that have helped build a community of devotees in Maharashtra?

Yes, the preface in Chapter 0 mentions another significant work that has been central to devotional communities in Maharashtra. Alongside the Shri Sai Satcharita, the text identifies the sweet and graceful biography written by Shri Saraswati Gangadhar about Shri Samarth Sadguru Narsimha Saraswati Maharaj. This work is now famously known as the Brihat or Thorale Guru Charitra. It is described as being well known to all, studied daily in thousands of places, and widely used for Parayans, indicating its foundational role in fostering and sustaining a large community of devotees.
