How does the story of Cholkar's vow serve as a practical demonstration of Sai Baba's philosophy on omnipresence?

Cholkar's story, found in Chapter 15, acts as a powerful illustration of Sai Baba's teachings on omnipresence. The narrative begins with a personal, secret act of devotion—Cholkar's vow to abstain from sugar while facing financial hardship far from Shirdi. The story culminates in Baba revealing His knowledge of this secret penance through the specific instruction about sugared tea. This concrete miracle serves as the foundation for the abstract teaching that follows. It proves Baba's claim that "Wherever you may be, if you spread your hands before me with faith, I am standing right there." The incident validates the idea that Baba is the "inner self" who knows a devotee's mind instantly, regardless of physical distance, thus making a profound philosophical concept tangible and real.
