Why was the act of giving rupees so significant in the stories of Karnik and Appasaheb?

In the narratives from Chapter 33, the significance of giving rupees lies not in the monetary value, but in the spiritual transaction of devotion, faith, and fulfillment of one's word. For Karnik, giving one rupee to Narsing Maharaj was a moment of profound spiritual connection, where it "felt like Sai himself was accepting the Rupee." For Appasaheb, the story is about a spiritual debt. He gave his word in his mind to give ten rupees, but when a fakir came, he hesitated. The text notes that the fakir was not a common beggar; this was a "pretext for Dakshina" to test Appa's resolve. The act of giving was a measure of undivided faith and follow-through on a promise made to the divine.
