Given that other books about Sai Baba already existed, why did the author feel it was necessary to write the Sai Satcharitra, according to Chapter 2?

According to Chapter 2, the author acknowledges that other works, such as Das Ganu's 'Bhakta-Lilamrut' and 'Santa-Kathamrut' and publications like 'Sai Prabha,' already chronicled Sai Baba's life. However, a doubt arose in the minds of listeners about the need for a new text. The author resolves this by explaining that Sai's life is like a vast, deep ocean or an infinite mine of jewels. No single person or book could ever completely describe it. As Chapter 2 states, the author felt like a small Titwi bird trying to empty the ocean, an impossible task, but felt one should find satisfaction in whatever can be told. The intention was to collect various stories to provide devotees with enthusiasm and steadiness of mind, believing the stories themselves offer peace from worldly troubles.
