Given that other books about Sai Baba already existed, how does the author of the Sai Satcharitra justify writing a new one in Chapter 2?

In Chapter 2, the author acknowledges that other works about Sai Baba already exist, which might make listeners question the need for a new text. He justifies his endeavor by comparing Sai’s life to a "vast ocean, an infinite mine of jewels." He likens himself to a small Titwi bird trying to empty this ocean, suggesting that the task of completely describing Sai's life is impossible. Therefore, as Chapter 2 explains, one should find satisfaction in whatever can be told, as Sai's unique and infinite stories provide peace from worldly troubles and steadiness of mind.
