What exactly was Cholkar's vow, and how did he finally complete it?

According to Chapter 15, Cholkar's vow was to avoid sugar as an "inedible substance" until he was able to make a pilgrimage to Shirdi. This was a significant personal sacrifice, as the text notes he even drank his tea without sugar. He undertook this vow because worldly matters and home expenses made it difficult for him to travel. Upon finally arriving in Shirdi, he completed his vow in a heartfelt manner. After receiving Sai Baba's darshan, he prostrated at Baba's feet, offered a coconut, and, with a pure heart, distributed sugar, expressing that all his desires had been fulfilled.
