If we are honest with ourselves, we know from our own experience that the more we try to find solutions to our problems through thinking about them, the more we start going around in circles, sometimes interminably. Buddhism counsels us to resist being abused by our conflicting emotions and to let go of excessive thinking. Emotions can be expressed in an unhealthy, self-destructive manner or in a healthy and constructive fashion. Similarly, we can think in a self-destructive, confused way, which reinforces our negative habits, or we can think in a constructive way. Buddhism emphasises that overindulgence in conflicting emotions and distorted forms of thinking only reinforces our old habits, which solidifies our karmic tendencies even further.
