What information is available about Guru biographies written by individuals other than Saraswati Gangadhar and Annasaheb Dabholkar?

The text provides details on several other Guru biographies. As mentioned in Chapter 0, Shri Dasganu Maharaj wrote two short but excellent biographies of Sai Baba. Additionally, Chapter 0 recalls a detailed and scholarly Guru biography written by Shri Samarth Sadguru Tembhe Swami, also known as Vasudevanand Saraswati Maharaj. It is noted that this work is not as famous as the one by Saraswati Gangadhar. There is also mention of a biography by Shri Samarth Sadguru Dattatreya Maharaj of Balekundri, though it had not been printed or published at the time of writing.
