Following the incident with Cholkar's vow, what profound spiritual teaching did Sai Baba give about His omnipresence?

After revealing His knowledge of Cholkar's secret vow through the instruction for sweetened tea, Sai Baba imparted a profound teaching about His true nature, as detailed in Chapter 15. Baba explained that He is not confined to His physical body in Shirdi. 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 declared that His true home is within the devotee's heart, stating, "I am your inner self." He expanded on this by explaining His presence in all beings, including insects, ants, animals, and every person one encounters, urging Cholkar to bow to the inner self within all, as it is Baba alone who acts through them.
