Can you describe the specific penance Cholkar undertook while waiting to fulfill his vow and what it reveals about his character?

While waiting to gather the resources to travel to Shirdi, Cholkar undertook a specific and personal penance. Chapter 15 states that because there was a delay in fulfilling his vow to distribute sugar candy, "he gave up sugar." He treated it as an "inedible substance" and went so far as to drink his tea without it. This action reveals a great deal about his character. It shows his deep sincerity, his unwavering resolve, and his profound respect for the promise he made to Sai Baba. Even when he couldn't perform the external act of the vow, he maintained its sanctity internally through personal sacrifice, demonstrating his strong devotion.
