What was the deeper spiritual lesson Sai Baba taught Cholkar through the incident with the sugar?

The incident with the sugar served as a prelude to a profound spiritual teaching from Sai Baba. According to Chapter 15, after revealing his knowledge of Cholkar's secret vow, Baba explained His omnipresent nature. He told Cholkar that even though His body was in Shirdi, He was aware of Cholkar's actions and thoughts from afar. Baba stated, 'Wherever you may be, if you spread your hands before me with faith, I am standing right there with your faith, day and night.' He further elaborated that He resides within the heart of every being, including insects and animals, and that Cholkar should see Baba in everyone he meets. The ultimate lesson was one of non-duality: 'you and I are one.'
