How does the Satcharitra explain Sai Baba's ability to know everything about Sapatnekar's life?

The Shri Sai Satcharitra explains Sai Baba's omniscience using profound spiritual concepts. After Sapatnekar heard his life story from Baba's mouth, he marveled at how Baba could know such intimate details. Chapter 48 clarifies this by stating that for Baba, everything was as clear as a "gooseberry in the palm of the hand." The text explains that Baba is the form of Brahman, and the entire universe is his family; in fact, he has manifested as the universe itself. Because he is merged with the Supreme Being, the language of duality, such as "mine" and "thine," does not apply to him. He is beyond the distinctions of seer, seeing, and seen, which is the ultimate sign of his divine nature.
