How did the incident with Cholkar's sugar vow serve as a practical demonstration of Sai Baba's teaching that He resides in the hearts of all beings?

The incident with Cholkar's sugar vow was a perfect practical demonstration of Sai Baba's abstract spiritual teachings. By revealing His knowledge of a secret vow—Cholkar's private renunciation of sugar—Baba provided tangible proof for his subsequent discourse. Chapter 15 shows that this miracle wasn't just a display of power; it was the foundation for a lesson. When Baba later stated, "My home is in your heart; I am your inner self" and "Whatever you do there, I know it instantly," Cholkar had just experienced undeniable evidence of this truth. The personal and specific nature of the revelation—knowing about the sugar in his tea—made the grand, philosophical concept of divine immanence and omnipresence intensely personal and believable for him.
