Can you explain the idea that Sai Baba is 'beginningless and endless' by comparing him to other saints mentioned in the text?

The text in Chapter 43 establishes Sai Baba's eternal nature by drawing parallels with other revered saints. It poses the rhetorical question, 'Did Maharaj Gyanoba (Gyaneshwar) leave?' before noting that he gave darshan three centuries after his passing. It explicitly states that just as there was Tukaram Maharaj in Dehu, Samarth Ramdas in Parli, and the one from Akkalkot in Akkalkot, 'Sai is the same in Shirdi.' This comparison serves to illustrate that Sai Baba is not just a historical figure but a manifestation of the same unending, divine principle that appears in different forms to protect and guide devotees.
