How could Sai Baba know every detail of Sapatnekar's life? Does the Satcharitra explain this power?

Yes, Chapter 48 of the Shri Sai Satcharitra provides a profound explanation for Sai Baba's omniscience following the incident with Sapatnekar. After hearing his life story from Baba's lips, Sapatnekar marveled at how Baba could know everything. The text explains that for Baba, all things were as clear as a "gooseberry in the palm of the hand." This is because Baba is described as being the form of Brahman itself, completely one with the universe. The book states that for one who has merged with the Supreme Being, there is no duality or distinction of "mine" and "thine." He is the "knower of the inner self," and the entire universe is his manifestation, which is why he knew Sapatnekar's story in its entirety.
