If you see things with real insight, then there is no stickiness in your relationship to them. They come – pleasant and unpleasant – you see them and there is no attachment. They come and they pass. Even if the worst kinds of defilement come up, such as greed or anger, there’s enough wisdom to see their impermanent nature and allow them to just fade away. If you react to them, however, by liking or disliking, that isn’t wisdom. You’re only creating more suffering for yourself.
