How did Sai Baba use the incident with Cholkar's tea to impart a deeper spiritual lesson?

The incident with the sweetened tea served as a powerful catalyst for a profound teaching from Sai Baba. After revealing His knowledge of Cholkar's secret vow by mentioning the sugar, Baba explained His omnipresence. According to Chapter 15, Baba stated, 'Even if my body is here, and you are beyond the seven seas, Whatever you do there, I know it instantly.' He elaborated that His true home is in the devotee's heart and that He is the inner self of all beings. Baba used this personal experience to teach Cholkar that He exists everywhere, in all creatures, and that the devotee and He are one. This transformed a simple story of a fulfilled vow into a lesson on divine immanence and the nature of faith.
