The preface mentions several Guru biographies. What makes the one by Shri Vasudevanand Saraswati Maharaj distinct from those by Dabholkar and Saraswati Gangadhar?

The preface acknowledges several Guru biographies, and the one by Shri Samarth Sadguru Tembhe Swami, also known as Vasudevanand Saraswati Maharaj, has a unique characteristic. As explained in Chapter 0, this work is detailed and scholarly. However, its most significant distinction is that it was written by the Maharaj himself. Because it is an autobiography, the preface explicitly states that it cannot be categorized in the same way as the Guru biographies written by Shri Saraswati Gangadhar (the Guru Charitra) and Shri Annasaheb Dabholkar (the Shri Sai Satcharita), which were written by devotees about their Gurus.
