Beyond the miracle with the tea, what were the profound spiritual teachings Sai Baba shared with Cholkar?

After revealing His knowledge of Cholkar's secret vow, Sai Baba imparted profound spiritual truths, as recorded in Chapter 15. Baba explained His omnipresence, 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 within the hearts of all beings, declaring, 'My home is in your heart; I am your inner self.' Baba extended this to all of creation, saying he is present in insects, ants, animals, and all people one might meet. The ultimate teaching was one of non-duality and unity: 'Do not keep any distance from me; you and I are one.' This experience offered Cholkar direct insight into Baba's all-pervading nature.
