What are the two most prominent, detailed Guru biographies in Maharashtra suitable for devotional reading, and who authored them?

The text identifies two particularly significant, comprehensive, and poetic Guru biographies in Maharashtra that are well-suited for 'Parayans' and 'Saptahs'. As mentioned in Chapter 0, the first is the older, sweet, and graceful biography of Shri Narsimha Saraswati Maharaj, which is famously known as the Brihat or Thorale Guru Charitra, written by Shri Saraswati Gangadhar. The second is the more recent, inspirational biography of Shri Sai Baba Maharaj, titled Shri Sai Satcharita.
