Based on Sapatnekar's story, how does the Shri Sai Satcharitra explain the philosophical basis for Sai Baba's ability to know everyone's inner thoughts and life story?

Chapter 48 explains that Sai Baba's omniscience, as demonstrated to Sapatnekar, stems from his true nature as the form of Brahman. The text states that for Baba, the entire universe is his family and that he has manifested as the universe itself. This is described as the "expansion of oneness." Because he is merged with the Supreme Being, the language of duality, such as the distinction between "mine" and "thine," does not exist for him. Everything is as clear to him as a gooseberry in the palm of one's hand. He is beyond the seer, the seeing, and the seen, which is why he is a great knower of the inner self.
