If we keep track of our emotional bursts, internal or external, and find they are frequent or hurtful, it reminds us of how far we still have to go on the path of true virtue. Indeed, living the virtues is good for one's health in many ways. One positive way we can sustain a regular spiritual blood flow is to leave vengeance to God. A caution We should be aware that our emotions and feelings can be elevated into the virtuous or degraded into vices. In the most virtuous persons there is a bit of vice, and in the most vile of persons there is a bit of virtue.
Every virtue has a corresponding vice.
Although virtue is found in actions that produce good, it is easier than we think to slide down the pole of a virtue into its opposing vice. We must always be on guard, for the pride of ego can easily be the grease on the pole. Sound virtue is the willingness to do something unwitnessed. We do not talk about virtuous actions, such actions speak for themselves. Here the virtues in themselves have become an end rather than a means to an end.
