What other saints does the author mention to draw a parallel with Sai Baba's eternal nature?

To illustrate that Sai Baba's presence transcends physical death, Chapter 43 draws comparisons to several other revered saints who are believed to be eternal. The author asks rhetorically if Maharaj Gyanoba (Gyaneshwar) truly left, noting that he gave darshan three centuries after his samadhi. Other examples cited include Nath Maharaj as the light of Paithan, Tukaram Maharaj in Dehu, Narasimha Saraswati in Alandi, Samarth Ramdas in Parli, the Swami of Akkalkot, and Prabhu Manik in Humnabad. By placing Sai Baba in Shirdi among this list, the text asserts that he is an immortal presence in the same vein, eternally accessible to his devotees.
