Why was Baba's instruction about giving Cholkar tea with sugar so significant?

Sai Baba's instruction to Jog to serve Cholkar tea "well-filled with sugar" was deeply significant because it was a deliberate act to affirm Cholkar's faith. As Chapter 15 points out, Baba himself did not drink tea, making his sudden and specific request highly unusual and purposeful. The true reason was to give Cholkar a clear sign that his secret vow of renouncing sugar and the long penance he endured were not only seen but also accepted by Baba. This miracle served to impress the "stamp of devotion" on Cholkar's mind. Baba later explicitly stated the purpose of this sign, telling Cholkar, "Your vow of sugar has been accepted, And your rule of renunciation is also complete," confirming that the secret vow was fully known to him.
