What specific promise did Cholkar make to Sai Baba, and why did it take him so long to fulfill it?

Cholkar, a man from a poor household, made a vow to Sai Baba to secure his job. As described in Chapter 15, he needed to pass an examination to make his salary permanent, and his livelihood was at stake. He vowed that if he passed with Baba's grace, he would visit Shirdi and distribute sugar candy (khadisakhar) in Baba's name. After his wish was granted, there was a significant delay in fulfilling the vow. The text explains this was due to financial hardship, poetically referring to the challenge of home expenses as a "threshold-ghat" that is very difficult for a worldly person to cross. He couldn't afford to make the journey right away and had to keep pushing the days forward.
