How does the story of Kaka Mahajani's companion demonstrate Baba's omniscience in the context of accepting Dakshina?

The account of Kaka Mahajani's friend in Chapter 35 serves as a clear demonstration of Baba's omniscience regarding a devotee's innermost thoughts on giving Dakshina. The friend had made a private vow not to give any money. Baba, without being told, knew this and consequently only asked Kaka for Dakshina, which made the friend feel uneasy. When the friend finally asked why he was being excluded, Baba revealed His knowledge by stating, "In your mind, there was no intent to give; Therefore, I did not ask you." This shows that Baba's requests for Dakshina were not random but were perfectly guided by His divine insight into the devotee's heart and readiness to give.
