Besides the Shri Sai Satcharita, what other major Guru biographies are mentioned in the text?

The text mentions several Guru biographies in addition to the Shri Sai Satcharita. As detailed in Chapter 0, the other primary work is the Brihat or Thorale Guru Charitra by Shri Saraswati Gangadhar, which is well known and used for daily study. The text also recalls a scholarly biography written by Shri Samarth Sadguru Tembhe Swami (Vasudevanand Saraswati Maharaj) himself, which is noted as not being in the same category as those written by devotees. Another by Shri Samarth Sadguru Dattatreya Maharaj of Balekundri is mentioned, but it was not yet printed or published. Finally, two short biographies by Dasganu Maharaj are cited.
