What was the philosophical lesson Sai Baba taught Cholkar after his vow was fulfilled?

After acknowledging Cholkar's vow with the miracle of the sugary tea, Sai Baba imparted a profound spiritual teaching about his true nature. As recorded in Chapter 15, Baba explained that his presence is not confined to his physical body in Shirdi. He told 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 he resides within the hearts of his devotees as their "inner self." He further elaborated on this omnipresence, stating that he exists in all beings and all places, from insects and ants to all people one might encounter. The ultimate lesson was one of unity: "Do not keep any distance from me; you and I are one."
