Why couldn't Cholkar immediately go to Shirdi after passing his exam, and what did he do to maintain his devotion during the delay?

After passing his examination through Sai Baba's grace, Cholkar was unable to immediately fulfill his vow to visit Shirdi due to his financial situation. Chapter 15 explains that he was from a poor household and describes the difficulty of crossing the "threshold-ghat," a metaphor for overwhelming home expenses. Despite this delay, his devotion did not waver. To demonstrate his sincerity and as a form of penance for not being able to travel, Cholkar took a personal vow to abstain from sugar. He considered it an inedible substance until he could complete his promised pilgrimage, going so far as to drink his tea without any sugar. This act shows his firm resolve and dedication even while facing worldly hardships.
