Describe the comparisons the author makes between Sai Baba and other great saints to support the idea of his eternal presence.

To illustrate Sai Baba's eternal and unbroken nature, the author in Chapter 43 draws parallels with other revered saints who are believed to be eternally present. The text specifically asks, 'Did Maharaj Gyanoba (Gyaneshwar) leave?' noting that he gave darshan three centuries after his samadhi. Other examples cited include Nath Maharaj becoming the light of Paithan, Tukaram Maharaj in Dehu, Narasimha Saraswati in Alandi, Samarth Ramdas in Parli, and the saint of Akkalkot. By placing Sai Baba in this lineage, the author asserts that just as those saints remain powerful presences in their respective holy places, 'Sai is the same in Shirdi,' and his influence is proven by the experiences of devotees even today.
