Chapter 2 mentions several other texts that already contain stories about Sai Baba. What are these texts, and why did the author feel it was still necessary to write a new book?

Chapter 2 acknowledges the existence of several other works about Sai Baba. These include Das Ganu's *Bhakta-Lilamrut* and *Santa-Kathamrut*, Raghunath-Savitri’s *Bhajanmala*, miscellaneous poems by Das Ganu, books for Gujarati devotees by Amidas and Bhavani Metha, and a series called *Sai Prabha* from Pune. Despite these existing texts, the author justifies this new book by explaining that Sai's life is like a vast, infinite ocean. It is impossible to describe it completely. Therefore, as Chapter 2 clarifies, the author believes that any collection of His stories is valuable, providing peace and enthusiasm to devotees.
