How does the author of the Sai Satcharitra justify writing another book about Sai Baba when several others already existed?

In Chapter 2, the author directly addresses the potential doubt about the need for this new text. He explains that Sai Baba's life is like a "vast ocean, an infinite mine of jewels," and it is impossible to describe it completely. Using the analogy of a small Titwi bird trying to empty the ocean, he suggests that one should find satisfaction in whatever can be told. The author believes that the unique and infinite stories of Sai provide peace from worldly troubles and give devotees enthusiasm and mental steadiness. Therefore, as this chapter explains, even with other works available, there is always more of Baba's deep life story to share.
