What is the deeper meaning behind the stories of Karnik's Rupee and Appasaheb's promise of ten Rupees?

The deeper meaning, as explained in Chapter 33, revolves around the nature of human resolve and the importance of fulfilling one's word in devotion. The text notes that the mind is full of 'resolves and counter-resolves' and that we should nurture our initial good inclinations. Appasaheb's story is used as a prime example; he made a heartfelt promise to give ten Rupees but hesitated when a mysterious Fakir appeared. The narrative suggests this was a test from Baba, posing the question: if there were no love for Appa, why would Baba come in Fakir form? The lesson is that while we are all 'devoted to verbal promises,' true devotion is shown by acting on them without hesitation, as certainty in such matters is rare.
