What do the scriptures say about how to handle the mind's tendency to change and have second thoughts, especially regarding good deeds?

The scriptures, as detailed in Chapter 33, teach that the mind is inherently filled with 'resolves and counter-resolves,' like waves in the sea. The story of Haribhau Karnik illustrates this perfectly. He had an initial, pure impulse to give Baba an extra rupee but then dismissed the thought. The key advice offered is that whatever good inclination first arises in the mind should be maintained and nurtured, as this path is ultimately beneficial. This suggests we should trust our initial, positive spiritual urges and not allow subsequent hesitation or rationalization to deter us from a good action.
