How does the author justify writing a new book about Sai Baba when several others were already available?

In Chapter 2, the author addresses the potential question of why another book on Sai Baba is necessary. He resolves this by comparing Sai's life to a 'vast ocean, an infinite mine of jewels,' implying that it is impossible for any single book to describe it completely. He likens himself to a small 'Titwi bird' attempting this impossible task, suggesting one should find satisfaction in whatever can be told. The author states that Sai's unique stories are infinite and provide peace from worldly troubles, giving devotees enthusiasm and steadiness of mind, thus justifying this new collection.
