Why did Cholkar get so emotional when Baba mentioned giving him sugary tea?

Cholkar's emotional reaction stemmed from the profound personal significance of Baba's words. As explained in Chapter 15, due to financial constraints, there was a long delay between Cholkar passing his exam and being able to fulfill his vow of distributing sugar candy in Shirdi. As a secret act of penance for this delay, he completely gave up sugar, even drinking his tea without it. When Baba, who knew this secret, specifically told Jog to give Cholkar tea 'well-filled with sugar,' it was a direct and powerful confirmation for Cholkar. He was amazed that Baba was aware of his hidden sacrifice, and tears of joy came to his eyes as his faith was profoundly affirmed.
