Can you explain the story about Appasaheb Kulkarni's promise to give ten rupees and what happened next?

Chapter 33 recounts the story of Appasaheb Kulkarni's unfulfilled promise. After his family gave a single Rupee to the Fakir (Sai Baba), Appasaheb felt this was insufficient and mentally resolved to give ten Rupees himself. However, he did not act on this immediately. The text explains that many days later, another Fakir, who was a stranger to Appasaheb, appeared. Because this Fakir was unfamiliar, Appasaheb became suspicious and did not offer the money, even though he had six Rupees readily available. This story serves as a lesson about the importance of fulfilling one's spoken or mental commitments without giving in to doubt.
