Based on Sapatnekar's story, how does the Shri Sai Satcharitra explain Sai Baba's ability to know everything about a person's life?

Sapatnekar's story serves as a powerful example of Sai Baba's divine nature, which is explained in Chapter 48 of the Shri Sai Satcharitra. After hearing his life story from Baba's mouth, Sapatnekar marveled at how Baba could know such details. The text clarifies that for Baba, everything was as clear as a "gooseberry in the palm of the hand." This is because Baba is the "form of Brahman" and has manifested as the entire universe, making the universe his family. The Satcharitra states that for one who is merged with the Supreme Being, the language of duality like "mine" and "thine" does not exist, as he himself is the world in detail and a great knower of the inner self.
