What philosophical understanding about Sai Baba did Sapatnekar gain after hearing his life story narrated?

After hearing his entire life story from Sai Baba's mouth, Sapatnekar gained a profound philosophical understanding of Baba's true nature. He realized that Baba was a "great knower of the inner self" to whom everything was as clear as a gooseberry in one's palm. The experience etched deep respect in his mind. As explained in Chapter 48 of the Shri Sai Satcharitra, Sapatnekar understood that Sai Baba is the form of Brahman, that the entire universe is His family, and that He has manifested as the universe itself. This insight dissolved the concepts of "mine" and "thine," revealing that for one who has merged with the Supreme Being, the language of duality does not exist.
