What specific sacrifice did Cholkar make, and how did Sai Baba acknowledge it?

Cholkar's vow was that if he passed his crucial job examination, he would distribute sugar candy in Sai Baba's name. However, as Chapter 15 explains, financial hardship, described as the difficult 'threshold-ghat' of home expenses, prevented him from immediately traveling to Shirdi. As a personal penance during this long delay, Cholkar completely abstained from sugar, viewing it as an 'inedible substance' and even drinking his tea without it. Sai Baba uniquely acknowledged this secret sacrifice after Cholkar had fulfilled his vow. Baba instructed Cholkar's host, Jog, to give him 'cups of tea, well-filled with sugar,' a specific and meaningful command that proved to Cholkar that his private act of devotion had been seen and accepted by Baba.
