Why did the author feel it was necessary to write a new book about Sai Baba when so many others already existed?

The author anticipates that listeners might question the need for another book. The justification provided in Chapter 2 is that Sai's life is like a vast, deep ocean, an infinite mine of jewels. The author compares their own effort to a small bird trying to empty this ocean, an impossible task. Therefore, it is impossible to describe Sai's life completely. The author concludes that one should find satisfaction in whatever can be told, as the infinite stories of Sai provide peace from worldly troubles and give devotees enthusiasm and steadiness of mind. Each new collection adds to the treasure.
