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

Chapter 2 directly addresses the potential doubt from listeners about the need for a new book, given that works by Das Ganu, Raghunath-Savitri, and others already existed. The author explains that Sai's life is like a vast, deep ocean or an infinite mine of jewels, making it impossible to describe completely. He humbly compares his effort to a small Titwi bird trying to empty the ocean. Therefore, as described in Chapter 2, the goal isn't to be exhaustive but to find satisfaction in sharing what can be told, providing devotees with peace, enthusiasm, and mental steadiness through these unique stories.
