Based on Sapatnekar's story, how does the Shri Sai Satcharitra explain the nature of Sai Baba's omniscience?

Chapter 48 provides a deep philosophical insight into Sai Baba's omniscience through Sapatnekar's experience. After Sapatnekar wondered how Baba could possibly know his entire life story, the text explains that for Baba, everything was as clear as "a gooseberry in the palm of the hand." The reason for this is that Baba is the form of Brahman itself, and the entire universe is His family. The scripture states that the expansion of oneness is the incarnation of Sai, meaning He has manifested as the entire universe. For one who is merged with the Supreme Being, the duality of "mine" and "thine" ceases to exist. The text beautifully illustrates that just as paint cannot stick to the sky, the worldly distinctions of seer, seeing, and seen did not apply to Baba, who was one with all existence.
