How does the author of the Sai Satcharitra justify the creation of a new book about Sai Baba in Chapter 2, given that other stories already existed?

In Chapter 2, the author anticipates readers questioning the need for another book on Sai Baba. The justification provided is a beautiful metaphor: Sai's life is compared to a vast, deep ocean, an infinite mine of jewels. The author portrays himself as a small Titwi bird attempting the impossible task of emptying this ocean. This analogy illustrates that Sai's life is too profound and expansive to be captured completely in any single work. Therefore, as Chapter 2 explains, any collection of His stories is valuable, as these infinite leelas provide peace from worldly troubles and give devotees enthusiasm and steadiness of mind.
