What philosophical truth about Sai Baba's nature is revealed through the story of Sapatnekar?

The story of Sapatnekar in Chapter 48 of the Shri Sai Satcharitra reveals Sai Baba's true nature as an all-pervading, omniscient being who embodies non-duality. By recounting Sapatnekar's entire life story to another person, Baba demonstrated that everything was as clear to him as a "gooseberry in the palm of the hand." The text explains this by stating that Baba is the form of Brahman, the entire universe is his family, and he has manifested as the universe itself. This means for Baba, there is no distinction between "mine" and "thine." He is merged with the Supreme Being, transcending the duality of seer, seeing, and seen, which is why he could know every detail of Sapatnekar's life.
