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

The incident with the sweetened tea served as more than just proof of omniscience; it was a gateway to a profound teaching. After startling Cholkar by mentioning the sugar, Baba explained the nature of his omnipresence. As detailed in Chapter 15, Baba clarified that even if a devotee is "beyond the seven seas," He is always with them, residing in their heart as their "inner self." He extended this concept by stating his presence in all living things, from insects and ants to all animals. Baba concluded this powerful lesson by telling Cholkar, "you and I are one," thus using a personal experience to reveal the non-dual truth and the immanence of the Divine to his devotee.
