Why did Cholkar give up sugar? Was it part of his original vow to Sai Baba?

Cholkar's decision to give up sugar was not part of his original vow but rather a personal act of penance. According to Chapter 15, after he passed his examination with Baba's grace, he was unable to immediately travel to Shirdi to fulfill his vow of distributing sugar candy due to financial constraints. To maintain his commitment and as a form of self-discipline during this delay, he chose to abstain from sugar entirely, going so far as to drink his tea without it. This secret sacrifice was known only to him until Sai Baba miraculously revealed His knowledge of it, demonstrating his deep connection with his devotees' inner states.
