Chapter 2 mentions that other books about Sai Baba already existed. How does the author justify the need for this new text?

The author anticipates that readers might question the necessity of a new book, given the existence of works by Das Ganu, the "Sai Prabha" series, and others. As detailed in Chapter 2, he justifies his work by comparing Sai's life to a "vast ocean, an infinite mine of jewels," which is impossible to describe completely. He uses the analogy of a Titwi bird trying to empty the ocean to illustrate the futility of a complete account. Therefore, he argues, one should find satisfaction in whatever can be told, and his collection of Sai's unique stories will provide peace, enthusiasm, and steadiness of mind to devotees.
