The Satcharitra describes Baba as being one with the universe. Can you explain this concept based on Sapatnekar's story?

In Sapatnekar's story, after he witnessed Baba narrating his entire life, he marveled at how Baba could know such details. Chapter 48 explains this by stating that Baba's omniscience is like seeing a gooseberry in the palm of one's hand because He is the form of Brahman. The text describes Baba as one for whom the entire universe is his family, having manifested as the universe itself. This is the sign of Sai. The Satcharitra elaborates that for one who has merged with the Supreme Being, the language of duality like "mine" and "thine" disappears. The seer, seeing, and the seen do not touch him, meaning Baba is not separate from the world but is the world in detail.
