Feelings and sensations cause us to suffer, because we fail to realize that they are impermanent. When we do not control our feelings, we are controlled by them. If we live in the moment, we can see things just as they are. Doing so, we can put an end to all desire, break our bondage, and realize peace. To understand pleasant, unpleasant, and neutral feelings, we have to put the four foundations of mindfulness into practice.
Mindfulness can transform pleasant, unpleasant, and neutral feelings into wisdom.
The world is created by the mind. If we can control feeling, then we can control the mind. If we can control the mind, then we can rule the world. In meditation, we relax our body, but we sit up straight, and, by following our breathing or another object of concentration, we stop most of our thinking. Therefore, we stop being pushed around by our feelings.
