How does the author of the preface position the Shri Sai Satcharita in the context of other major Guru biographies in Maharashtra?

The preface in Chapter 0 highlights a scarcity of detailed, poetic, and comprehensive Guru biographies in Maharashtra suitable for devotional readings. It identifies only two major works that fit this description. The first is the ancient and revered Shri Guru Charitra by Shri Saraswati Gangadhar. The second is the recent and inspirational Shri Sai Satcharita, written by Annasaheb Dabholkar about Sai Baba. By placing the Shri Sai Satcharita alongside the famous Guru Charitra, the author elevates its importance, presenting it as a modern masterpiece filling a significant spiritual and literary need for devotees.
