How is Sai Baba's continued presence after his physical death explained, and are there parallels with other saints?

Sai Baba's continued presence is explained by his transcendence of the material state. As detailed in Chapter 43, he merged into the unmanifest, his true self, and continues to reside in the hearts of his followers, remaining unbroken even at the end of the universe. He is described as the protector of his devotees' cause, filling the entire world in his true form. This is not unique, as the text draws parallels to other great saints. For instance, Maharaj Gyaneshwar gave darshan three centuries after his passing. Just as Tukaram Maharaj is associated with Dehu and Samarth Ramdas with Parli, Sai is eternally present in Shirdi and beyond, proving his influence and making the concept of death irrelevant for him.
