What are the two primary detailed Guru biographies from Maharashtra that are mentioned as being suitable for devotional reading (Parayan)?

The source material identifies two major detailed and comprehensive Guru biographies well-suited for Parayans and Saptahs. As noted in Chapter 0, the first is the biography of Shri Samarth Sadguru Narsimha Saraswati Maharaj, written by Shri Saraswati Gangadhar, famously known as the Brihat or Thorale Guru Charitra. The second significant work mentioned is the more recent biography of Shri Sachidanand Samarth Sadguru Sai Baba Maharaj, written by the devotee Shri Govind Raghunath, also known as Annasaheb Dabholkar. This work, titled Shri Sai Satcharita, is described as sweet, inspirational, and grace-filled, and along with Guru Charitra, is noted as a rare example of a detailed biography.
