What was the specific vow that Cholkar made to Sai Baba, and what was his motivation for making it?

Cholkar, facing financial instability, had his entire livelihood dependent on passing an examination to make his job salary permanent. As recounted in Chapter 15, his situation was precarious, with his daily bread at stake. In this state, he made a firm vow to Sai Baba. He promised that if he passed the exam by Baba's grace, he would present himself at Baba's feet in Shirdi and distribute sugar candy (khadisakhar) in His name. This vow was born out of his need for divine assistance in a critical moment of his life, where success was essential for his survival.
