It is common after a major event to have difficulty getting back into our daily routine. Whether it is a child's wedding, an exotic vacation or a summer at camp, rarely do we feel ready to return to our daily schedule. Surely the excitement of the events surrounding the receiving of the Torah at Sinai would seem to affect our daily activities similarly! The thunder, lightning, and masses of people all gathered to hear the first two commandments directly from G-d would have put one on a spiritual high from which it must have been hard to come down.
It is hard enough to do what is right. Our wants, desirers, egos, social pressure, and the like often get in the way of acting properly. Even when we do the right thing, our motivation may not be the purest. We may act the way we do as a method of receiving the accolades of others; for honour, wealth, or acceptance in a social group.
