When we reach the state of nonaggression, it is not that we cease to perceive anything, but we begin to perceive in a particular way. With the absence of aggression, there is further clarity, because nothing is based on anxiety and nothing is based on ideas or ideals of any kind. Instead, we are beginning to see things without making any demands. We are no longer trying to buy or sell anything to anybody. It is a direct and very personal experience.
