Why is the biography by Shri Samarth Sadguru Vasudevanand Saraswati Maharaj considered to be in a different category from the Shri Sai Satcharita?

The Guru biography written by Shri Samarth Sadguru Vasudevanand Saraswati Maharaj is placed in a separate category for a specific reason outlined in Chapter 0. While it is acknowledged as a detailed and scholarly work, the preface states that because this biography was written by the Maharaj himself—the Guru writing about his own lineage or experiences—it cannot be categorized in the same way as biographies written by devotees about their Guru. This distinguishes it from works like the Shri Sai Satcharita, written by the devotee Annasaheb Dabholkar, and the Guru Charitra, written by the devotee Shri Saraswati Gangadhar.
