The text mentions other books about Sai Baba already exist. Why did the author feel the need to write another one?

The author acknowledges that other works about Sai Baba existed, such as those by Das Ganu, Raghunath-Savitri, and publications like Sai Prabha. As detailed in Chapter 2, he addresses this potential doubt by comparing Sai's life to a vast, deep ocean, an infinite mine of jewels. He feels that it is impossible for any single work to describe Sai's life completely. Therefore, he believes one should find satisfaction in whatever can be told, and his effort is like a small Titwi bird trying to empty this ocean. His goal is to provide peace, enthusiasm, and steadiness of mind to devotees through these countless stories.
