What philosophical explanation does the Shri Sai Satcharitra offer for Sai Baba's ability to know Sapatnekar's entire life story?

Chapter 48 provides a profound spiritual explanation for Sai Baba's omniscience. After Sapatnekar marveled at how Baba could know his story, the text clarifies that Baba is the form of Brahman and the entire universe is his family. It posits that he has manifested as the whole universe, which is the "sign of Sai." Because of this complete oneness, distinctions like "mine" and "thine" are nonexistent for him. The text explains that for one who is merged with the Supreme Being, the language of duality does not apply, just as "paint does not stick to the sky," illustrating his transcendent unity with all of existence.
