Why did Cholkar delay his trip to Shirdi, and what personal sacrifice did he undertake during this period?

After Cholkar's wish was granted and he passed his examination, there was a delay in him fulfilling his vow. Chapter 15 explains that for a worldly man, managing home expenses is a very difficult obstacle, likened to crossing a great mountain pass. This suggests his delay was due to financial or domestic responsibilities. During this waiting period, Cholkar demonstrated his commitment by making a personal sacrifice. He gave up sugar, considering it an inedible substance until he could fulfill his promise to Baba. He even went so far as to drink his tea without sugar, a penance that remained a secret until his visit to Shirdi.
