When did other saints demonstrate their continued existence after physical death, and how does that relate to Sai Baba?

Chapter 43 draws a direct parallel between Sai Baba and other great saints to illustrate that physical death is not an end. It specifically mentions the case of Maharaj Gyanoba (Gyaneshwar), who 'gave darshan after three centuries.' This event, where Nath Maharaj met him, is presented as proof of a saint's continued existence. The text then equates Sai Baba's presence in Shirdi to that of other saints like Tukaram Maharaj in Dehu and Samarth Ramdas in Parli. This comparison serves to reassure devotees that just as those saints remained accessible after leaving their bodies, Sai Baba also remains unbroken and present.
