Aversion generates karma with heavy consequences. On the other hand, practicing patience generates the most merit.
When the heart is free from aversion, one is at peace with the world. Aversion in the heart makes life difficult. It also makes the people around us uneasy, robbing them of calmness. A heart filled with aversion will destroy our own happiness, as well as the happiness of others.
So, practice the wisdom of patience in order to destroy the aversion. A person who knows how to extinguish the fire of aversion in this life will experience happiness in the next.
