According to Chapter 2, why did the author feel it was necessary to write a new book about Sai Baba when other works already existed?

The author acknowledges that other works about Sai Baba already existed, such as those by Das Ganu and publications like Sai Prabha. However, as explained in Chapter 2, he justifies this new text by comparing Sai’s life to a "vast ocean, an infinite mine of jewels." He posits that Sai's life is too deep and his stories too countless for any single work to describe them completely. Therefore, the author believes there is great value in collecting and sharing more of these unique stories, which he notes provide peace from worldly troubles and give devotees enthusiasm and steadiness of mind.
