The text says Baba knew Sapatnekar's story like a 'gooseberry in the palm of the hand.' What is the philosophical explanation for Baba's all-knowing nature?

The phrase 'like a gooseberry in the palm of the hand' signifies that everything was completely clear and known to Sai Baba. Chapter 48 of the Shri Sai Satcharitra provides a deep philosophical explanation for this omniscience. It states that Baba is the very 'form of Brahman' and that the entire universe is his family. The text explains that Sai is an incarnation representing the 'expansion of oneness,' meaning he has manifested as the entire universe itself. 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. For one who has become the world in detail, there are no secrets, which is how he could know and narrate Sapatnekar's entire life story.
