How do the stories of Karnik and Appasaheb in Chapter 33 contrast with each other regarding faith and giving?

Chapter 33 masterfully contrasts two different devotee responses to illustrate the nuances of faith. Karnik's story represents spontaneous, unhesitating faith. When a saint, whom he felt was a manifestation of Sai, demanded a Rupee, he gave it instantly and joyfully without prior thought. In stark contrast, Appasaheb's story shows the struggle between a premeditated good intention and the failure to act due to suspicion. He resolved to give a larger sum but hesitated when the opportunity came in an unexpected form. This comparison highlights that while one devotee acted purely on impulse and faith, the other's resolve was tested and found wanting, demonstrating the spiritual challenge of maintaining faith when faced with the unfamiliar.
