What is the significance of Cholkar giving up sugar in relation to Sai Baba's eventual miracle for him?

The significance lies in the deeply personal and secret nature of Cholkar's sacrifice. According to Chapter 15, when Cholkar was unable to fulfill his public vow of distributing sugar candy due to poverty, he undertook a private penance by renouncing sugar himself, even drinking his tea without it. This secret act of devotion became the key that unlocked Baba's miracle. Sai Baba's seemingly random instruction to give Cholkar "tea, well-filled with sugar" was not random at all; it was a direct and powerful confirmation that He was aware of Cholkar's most private sacrifice. This experience showed Cholkar that Baba knew his secret mind, his financial struggles, and his unwavering devotion, thereby transforming a simple cup of tea into a profound validation of faith.
