What does the text say about the importance of fulfilling promises, especially those made in devotion?

The provided texts from Chapter 33 strongly emphasize the significance of fulfilling one's word, particularly in the context of devotion. The story of Appasaheb is used as an example; he mentally promised to give ten Rupees to a Fakir. The text questions how he could be 'debt-free' without fulfilling this promise, implying a spiritual debt. It contrasts this with the common human tendency to be 'devoted to verbal promises' but hesitate when the time comes to act. The narrative suggests that Baba, even in the guise of a Fakir, is not an ordinary beggar and that these interactions are a test and an opportunity for devotion. The ultimate lesson is that a true devotee will strive to make their word true, as this firm practice is a core part of undivided faith.
