What profound spiritual lesson did Baba give to Cholkar after revealing He knew his secret?

After the incident with the sugary tea, Sai Baba imparted a profound teaching on his omnipresence and the nature of devotion. As narrated in Chapter 15, Baba explained that physical distance is meaningless. He assured Cholkar, "Even if my body is here, and you are beyond the seven seas, Whatever you do there, I know it instantly." Baba revealed that His true home is within the devotee's heart, as He is the "inner self." He instructed Cholkar to bow to this inner self, emphasizing that He exists in all beings—from insects and ants to all animals and people. The ultimate lesson was one of non-duality: "you and I are one."
