Besides the Shri Sai Satcharita, what other major Guru biography is mentioned, and what characteristics do these two works share?

The text from Chapter 0 notes that in Maharashtra, there are very few ancient, detailed, and poetic works suitable for Parayans. Besides the recent Shri Sai Satcharita, the other major work mentioned is the biography of Shri Samarth Sadguru Narsimha Saraswati Maharaj, written by Shri Saraswati Gangadhar. This work is famously known as the Brihat or Thorale Guru Charitra. Both the Guru Charitra and the Shri Sai Satcharita are distinguished by being detailed, comprehensive, poetic, grace-filled, and widely used for daily study and devotional Parayans by thousands of devotees.
