Although we are all the same in not wanting problems and wanting a peaceful life, we tend to create a lot of problems for ourselves. Encountering those problems, anger develops and overwhelms our mind, which leads to violence. A good way to counter this and to work for a more peaceful world is to develop concern for others. Then our anger, jealousy and other destructive emotions will naturally weaken and diminish.
Greed, desire, ambition, jealousy, possessiveness, domination - you have to watch everything. And they are all interconnected, remember. If greed disappears, then anger will disappear. If anger disappears, jealousy will disappear. If jealousy disappears, violence will disappear. If violence disappears, possessiveness will disappear. They are all intertwined. In fact, they are spokes of the same wheel, and the hub that supports them all is the ego. So watch the ways of the ego.
What I needed most was to love and to be loved, eager to be caught. Happily I wrapped those painful bonds around me; and sure enough, I would be lashed with the red-hot pokers or jealousy, by suspicions and fear, by burst of anger and quarrels.
