Chapter 2 mentions that other books about Sai Baba already existed. Why did the author feel it was necessary to write this new text?

The author acknowledges that a doubt may arise in the listeners' minds about the need for a new book when works by Das Ganu, Amidas, Bhavani Metha, and the Sai Prabha series already exist. As explained in Chapter 2, the author resolves this by comparing Sai’s life to a vast, infinite ocean or a mine of jewels. He sees himself as a tiny Titwi bird attempting to empty this ocean, an impossible task. Therefore, he believes that one should find satisfaction in whatever can be told, as Sai's unique and infinite stories provide peace from worldly troubles and give devotees enthusiasm and steadiness of mind.
