Can you summarize Cholkar's entire story and the main takeaway about devotion from his experience in Shirdi?

Cholkar's story, found in Chapter 15, is a powerful illustration of faith and divine omniscience. He made a vow to give up sugar until he could afford to visit Shirdi, a sacrifice he maintained by drinking his tea unsweetened. Upon finally reaching Shirdi, he fulfilled his vow by distributing sugar. The climax of his visit occurred when Sai Baba, who didn't drink tea, told Cholkar's host to serve him tea "well-filled with sugar." This act revealed Baba's complete awareness of Cholkar's secret vow and the long delay, causing Cholkar to weep with joy. The key takeaway is Baba's subsequent teaching: He is omnipresent, residing in the heart of every devotee, aware of their every act of faith, no matter where they are. Baba's message was clear: "Wherever you may be, if you spread your hands before me with faith, I am standing right there with your faith, day and night."
