What are the two most significant and detailed Guru biographies from Maharashtra mentioned in the text, and who authored them?

The provided text from Chapter 0 notes a general scarcity of detailed, poetic, and comprehensive spiritual biographies suitable for Parayans in Maharashtra. However, it highlights two major exceptions. The first is the renowned "Brihat or Thorale Guru Charitra," a sweet and graceful biography of Shri Samarth Sadguru Narsimha Saraswati Maharaj, which was written by Shri Saraswati Gangadhar. The second is the more recent "Shri Sai Satcharita," an inspirational work about the modern saint Shri Sai Baba Maharaj. This biography was authored by the late devotee Shri Govind Raghunath, also known as Annasaheb Dabholkar, and is described as being uniquely detailed alongside the Guru Charitra.
