Emotion is feeling with memories attached. Feeling is pure experience, it is the bridge between mind and body. We have a talent for making up things to block our way. We don't have a penny more than what we think we are worth. Violence comes from a sense of powerlessness.
Anger happens when someone breaks our rules.
What we resist persists. It is not your obligation to make someone happy. It is not their obligation to make you happy. Everyone is responsible for their own happiness. Control is an illusion.
