Can you describe the specific interaction with tea that revealed Sai Baba's omniscience to Cholkar?

The pivotal moment for Cholkar occurred after he had his darshan and was visiting his host, a man named Jog. As Cholkar, the guest, was about to leave, Sai Baba instructed Jog, "Give him cups of tea, well-filled with sugar." As noted in Chapter 15, this was highly significant because Baba himself did not drink tea, making the specific instruction about sugar deeply meaningful. Upon hearing these words, Cholkar was amazed because he knew the secret significance—it was direct proof that Baba was aware of his private vow to abstain from sugar, a fact he had kept to himself.
