Beyond knowing Cholkar's secret, what larger spiritual lesson did Baba impart through this incident?

The incident with Cholkar's tea served as a gateway to a much deeper spiritual teaching from Sai Baba, which is elaborated upon in Chapter 15. After revealing His knowledge of the secret vow, Baba explained His omnipresent nature, stating, 'Even if my body is here, and you are beyond the seven seas, Whatever you do there, I know it instantly.' He taught that He resides in the devotee's heart as their inner self and is present in all beings, including insects, ants, and animals. The ultimate lesson was one of non-duality: 'Do not keep any distance from me; you and I are one.' The experience was designed to show Cholkar, and all devotees, that Baba is always with them and within them.
