How does the author justify writing a new book about Sai Baba's life in Chapter 2 when other accounts already existed?

In Chapter 2, the author anticipates the question of why another book on Sai Baba is necessary. The justification provided is that Sai’s life is like a vast, infinite ocean or a mine of jewels that cannot be fully captured by any single work. The author uses the metaphor of being a small Titwi bird trying to empty the ocean to illustrate the impossibility of describing Sai's life completely. Therefore, the author argues that one should find satisfaction in whatever can be told, as the unique and infinite stories of Sai provide peace from worldly troubles and enthusiasm to devotees.
