What was Cholkar's situation that led him to make a vow to Sai Baba about distributing sugar candy?

Cholkar came from a poor household where everything depended on his job. To make his salary permanent, he had to pass a critical examination. As described in Chapter 15, his daily bread was at stake, and failure meant his candidacy would be lost. Facing this immense pressure, he made a firm resolve and vowed to Sai Baba that if he passed the exam by Baba's grace, he would visit Shirdi and distribute sugar candy (khadisakhar) in Baba's name. This vow was a plea for divine assistance in a moment of great personal and financial need.
