Why did Cholkar have to give up sugar, and what was the reason for the delay in fulfilling his vow to Sai Baba?

According to the account in Chapter 15, Cholkar's delay in fulfilling his vow was due to his poverty. The text poetically describes the difficulty of crossing the 'threshold-ghat,' meaning his household expenses were a significant barrier, and he could not go to Shirdi empty-handed. He had to push the journey from 'today to tomorrow' until he had the means. To maintain his resolve and as a form of personal penance during this waiting period, Cholkar made a rule for himself to avoid sugar as if it were an 'inedible substance,' even drinking his tea without it. This sacrifice was a secret he kept until he could finally complete the vow he had made to Baba.
