The text compares Sai Baba to other saints like Gyaneshwar and Tukaram. What is the purpose of these comparisons in understanding Baba's nature?

The purpose of comparing Sai Baba to other great saints is to illustrate the eternal nature of such enlightened beings. Chapter 43 points out that just as Gyaneshwar gave darshan centuries after he left, and figures like Tukaram Maharaj and Samarth Ramdas became eternal lights in their respective places, Sai Baba is likewise ever-present in Shirdi. This parallel reinforces the concept that Baba is beyond birth and death. His influence is proven by the fact that devotees can still experience his presence based on their own feelings, demonstrating that he has merged with the unmanifest and fills the entire world.
