A catharsis is needed because your heart is so suppressed, due to your brain. Your brain has taken over so much of your being that it dominates you… Then catharsis is needed to unburden the heart, to throw off suppressions, to make the heart open. If the heart becomes light and unburdened then the center of consciousness is pushed still lower; it comes to the navel. The navel is the source of vitality.
