You mention several Guru biographies. Which one is considered less famous than Saraswati Gangadhar's and why is it categorized differently from the works of Gangadhar and Dabholkar?

The text points to a Guru biography written by Shri Samarth Sadguru Vasudevanand Saraswati Maharaj. According to Chapter 0, this work, while scholarly and detailed, has not achieved the same level of fame as the biography by Shri Saraswati Gangadhar. The primary reason it is categorized separately from the works of both Shri Saraswati Gangadhar and the late Shri Annasaheb Dabholkar is its authorship. As Chapter 0 clarifies, this specific biography was written by the Maharaj himself, which fundamentally distinguishes it from biographies written by devotees like Gangadhar and Dabholkar.
