I heard about a poor devotee named Cholkar who made a vow to Sai Baba. Can you explain what the vow was for and why he had so much trouble fulfilling it?

A devotee named Cholkar, who came from a poor household, depended on his job for survival. To make his salary permanent, he had to pass an examination. As detailed in Chapter 15, he made a vow to Sai Baba that if he passed the exam by Baba's grace, he would visit Shirdi and distribute sugar candy (khadisakhar). Although he successfully passed, he could not immediately fulfill his promise. The text explains this delay by stating, "for a worldly man, this 'threshold-ghat' (home expenses) is very difficult to cross." This indicates that his financial struggles and the cost of daily living prevented him from making the journey sooner.
