How does the incident with Cholkar's tea demonstrate Sai Baba's omniscience and connection to his devotees?

The incident with Cholkar's tea powerfully demonstrates Sai Baba's omniscience and intimate connection with his devotees. According to Chapter 15, Baba himself did not drink tea, so his sudden and specific instruction to Jog to serve Cholkar tea 'well-filled with sugar' was highly unusual. This was not a random comment but a direct and personal message for Cholkar. It proved that Baba was aware of Cholkar's secret and self-imposed penance of abstaining from sugar due to the delay in fulfilling his vow. By revealing this hidden knowledge, Baba confirmed that his consciousness is not bound by physical distance and that he is always aware of his devotees' innermost thoughts and actions, thereby giving Cholkar 'a full hint' that his vow and subsequent sacrifice were accepted.
