Bhagavad Gita gives a very nice teaching: If something is very pleasurable in the beginning, we can experience dissatisfaction afterwards. For example, those extra pieces of burfi. The tongue is happy, but we may not feel so good later. In fact, a good lesson here is that:
SENSE GRATIFICATION KILLS MOTIVATION.
Try cleaning up the kitchen after stuffing yourself with more prasada than you actually need. Not very pleasant, right? And then there may be the desire to just leave things a mess until after a nap or something.
Compare that to the happiness of saving time by instead not over eating and promptly finishing cleaning up afterwards. The Bhagavad-Gita again confirms that what may not be so pleasant in the beginning, such as having to clean up instead of enjoying more of something delicious, results in feeling good about our selves afterwards
Sometimes, we hear an acharya preaching to the mind. Turns out the tongue needs a lot of preaching to as well! I mean, why do we put ourselves into a difficult situation just for that little sense organ called the “tongue”? Again, Bhagavad-Gita explains that it’s due to lust. Our original love for Krishna has been reduced to lust.
So even better than preaching to the tongue or remembering that happiness comes from doing service rather than sense gratification, is to do everything for the pleasure of the Lord. Whatever we do all throughout the day we can ask ourselves, “Is this pleasing to Krishna?’ and try to surrender and do everything with love, devotion, appreciation, and so on, invoking the Lord’s causeless mercy upon us.
