What is the philosophical explanation given in the text for how Sai Baba could know every detail of Sapatnekar's life?

After Sapatnekar wondered how Baba could know his life story, the text explains that for Baba, everything was as clear as a "gooseberry in the palm of the hand." Chapter 48 of the Shri Sai Satcharitra elaborates on this by stating that Baba is the form of Brahman and the entire universe is his family. He has manifested as the universe itself, eliminating any distinction between "mine" and "thine." Because he is merged with the Supreme Being, the language of duality does not apply to him, granting him complete knowledge of all things.
