How does the story of Appasaheb illustrate the spiritual importance of fulfilling a spoken promise?

The story of Appasaheb, detailed in Chapter 33, serves as a powerful lesson on the importance of matching one's actions to their words. After his family gave one Rupee, Appasaheb felt it was insufficient and declared that he would have given ten Rupees. The text explains that by giving his word, he became spiritually indebted and needed to fulfill this promise. Later, when a Fakir, implied to be Baba in disguise, appeared, Appasaheb hesitated and was suspicious. This highlights the common human failing of making grand verbal promises but then becoming downcast and hesitant when the time comes to act, emphasizing how rare it is for someone to be true to their word.
