It seems like a coincidence that Baba mentioned sugar in Cholkar's tea. Is there any evidence in the text that this was a deliberate act to prove his omniscience?

The text provided in Chapter 15 strongly refutes the idea of coincidence and presents Baba's actions as entirely deliberate. It explicitly states that Baba himself did not drink tea, which makes his specific instruction about sugar highly unusual. The narrative then provides the reason directly: 'It was so that Cholkar’s faith would be confirmed and the stamp of devotion would be impressed.' Baba later verbalizes this omniscience, telling Cholkar that his vow, the state of his mind, and the 'penance of the long delay' were all known to him despite being kept secret. This confirms the act was a compassionate and intentional lesson for his devotee, not a random occurrence.
