What was the specific vow Cholkar made to Sai Baba and what were the circumstances that led to it?

Cholkar came from a poor household and his livelihood depended on his job. To make his salary permanent, he was required to pass an examination. As described in Chapter 15, his situation was precarious, as failing the exam meant even his daily bread was at stake. Facing this challenge, he made a firm resolve and a vow to Sai Baba. He promised that if he passed the examination by Baba's grace, he would present himself at Baba's feet in Shirdi and distribute sugar candy, or 'khadisakhar', in Baba's name. This vow was born out of his desperate need for divine assistance to secure his worldly employment.
