Although our experiences strongly suggest otherwise, emotions are not the result of situational dynamics. You aren’t angry because someone behaved inappropriately. You aren’t happy as a result of circumstances working out in a particular way. This runs so counter to intuition and belief. But emotion is the result of a choice in the mind, having absolutely nothing to do with anything external to the self. In fact, what transpires in the "outside world" is merely a smokescreen, intentionally hiding the source of suffering.
