How does the text describe the fickle nature of the human mind regarding acts of devotion and charity?

Chapter 33 provides a deep reflection on the human mind, describing it as being of the nature of "resolves and counter-resolves," with thoughts coming in waves. It suggests that a good, charitable impulse may arise initially, but second thoughts and hesitation often follow. This is shown when the text states that many devotees are committed to verbal promises but hesitate greatly at the actual time of giving, causing their spirit to become downcast. The narrative advises that the very first good inclination that arises in the mind is the one that should be nurtured and maintained through firm practice, as that alone is truly beneficial for spiritual progress.
