Why did Cholkar decide to give up sugar, and how was this personal sacrifice acknowledged by Sai Baba?

Cholkar decided to give up sugar as a form of self-imposed penance. According to Chapter 15, after he passed his examination as he had prayed for, he was unable to immediately travel to Shirdi to fulfill his vow due to his poverty and household expenses. Feeling troubled by this delay, he took a personal resolution to avoid sugar as an "inedible substance," even drinking his tea without it. This secret sacrifice was profoundly acknowledged by Sai Baba in Shirdi. After Cholkar fulfilled his public vow, Baba specifically told another devotee, Jog, to serve Cholkar cups of tea that were "well-filled with sugar," demonstrating that He was fully aware of Cholkar's private act of renunciation.
