How does the Shri Sai Satcharitra explain Sai Baba's ability to know the intimate details of Sapatnekar's life?

Chapter 48 of the Shri Sai Satcharitra explains that Sai Baba's omniscience stems from his true nature as being one with the Supreme Being. The text states that for Baba, everything was as clear as "a gooseberry in the palm of the hand." This is because he himself is the form of Brahman, and the entire universe is his family. The Satcharitra elaborates that Baba has manifested as the entire universe, so the distinction between "mine" and "thine" does not exist for him. Since he is merged with the Supreme Being and embodies the expansion of oneness, there is no language of duality, allowing him to be the "great knower of the inner self" and perceive everything.
