I heard a story about Appasaheb and a promise involving ten Rupees. What's the background on that?

The story of Appasaheb is detailed in Chapter 33. Appasaheb felt that a single Rupee given by his family to a Fakir, who was Baba, was an insufficient amount. He mentally resolved that if he had been there, he would have given ten Rupees instead. This created a spoken, albeit internal, promise. The narrative then questions how Appasaheb could be considered free from this debt without fulfilling his word. This promise becomes a central theme, with the text explaining that the Fakir was not an ordinary beggar and that this was a pretext for Baba to engage with Appasaheb's devotion.
