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

Chapter 48 explains that Sai Baba's omniscience stems from his true nature as the form of Brahman, being completely one with the universe. For him, there is no distinction of "mine" and "thine" because he has manifested as the entire cosmos, and the universe is his family. The text posits that for one who has merged with the Supreme Being, the language of duality does not exist. This is why everything was as clear to Baba as a "gooseberry in the palm of the hand," allowing him to know Sapatnekar's entire life story from birth.
