Besides the Shri Sai Satcharita, what other major Guru biography is mentioned as being suitable for devotional study in Maharashtra?

The preface in Chapter 0 highlights two particularly significant Guru biographies that are suitable for Parayans and Saptahs in Maharashtra. The first one mentioned is the 'Brihat or Thorale Guru Charitra.' This is described as an ancient, sweet, and graceful biography written by Shri Saraswati Gangadhar about Shri Samarth Sadguru Narsimha Saraswati Maharaj. This work is noted as being famous and widely studied daily in thousands of places. The second major work is the Shri Sai Satcharita. The text emphasizes that no third work written in such comprehensive detail is found.
