Rage has been my good friend and teacher, an amazing force in my life. That power, such awesome power, has been a wonderful guide.
We live in a culture that fears anger, and is fully repulsed by rage. And perhaps that might be an acceptable defense mechanism. We all have experienced anger and rage misused (i.e. repressed), and yup, it can be a highly uncomfortable force. Repression of anger creates an underground turbulence, kind of like living near an earthquake fault line, with constant trembles threatening to erupt, hinting at a massive explosion. And because repression is ultimately futile, it will reach a limit, and then add even more force to the explosion of anger when it finally releases.
And repression is still the major operating force here in our culture, especially of anger and rage.
Our culture is wrought with layers and layers of expected behavior, and our automatic movement to repress our anger and rage can be invisible. We have even built a whole spiritual ideal that defines anger as wrong, problematic, and unnecessary. I often bump up against the argument that a mature spiritual life means never having to experience anger or rage; that anger can, and should, be replaced with a more mindful, or patient, or meditative state. The argument is that any of these "better" qualities can replace the "base" emotion of anger, and be a shining example of one's supreme spiritual evolution!
