 On the other hand, if we observe a person in a peaceful state, the breathing is deep, smooth, slow, and rhythmical. These examples show that there is a strong correlation between the pattern and the rhythm of breathing and a person’s emotional state, or more generally, state of mind. Zen breathing has a way of naturally heightening the positive correlation between the activity of the autonomic nervous system and emotion. Neurophysiologically, it happens that the center where breathing is regulated and the region where emotion is generated coincide. This means that the conscious breathing psychologically affects the pattern of how one generates emotion, and at the same time it also has a neurophysiological effect on how the autonomous activity of the unconscious is regulated. We will now move on to the third step involved in meditation.
