Can you summarize the entire story of Cholkar, from his initial problem to the confirmation of his faith in Shirdi?

The story of Cholkar, found in Chapter 15, begins with his anxiety over a job examination that his livelihood depended on. He made a vow to Sai Baba to distribute sugar candy in Shirdi if he passed. His prayer was answered, but due to financial difficulties, he couldn't immediately make the journey. As a personal penance for this delay, he gave up sugar. When he finally reached Shirdi, he fulfilled his vow. The story's climax occurs when Baba, knowing Cholkar's secret sacrifice, instructs Mr. Jog to serve Cholkar tea that is "well-filled with sugar." This act confirmed Baba's omniscience for Cholkar, who was overcome with joy, and led to Baba's teaching that He resides in the hearts of all.
