We are social and political beings. From an evolutionary point of view our brain has developed in order to help us survive.
Buddhism offers the hope of living in a world were other human beings do not represent a threat. One of the ways our body/brain regulates threat is through the autonomic nervous system. Habits of connection or protection. We want to shape our nervous system to be more open and less fearful. Zazen makes an important contribution to relaxing and opening the heart to our own fears and the fear of the other, shaping our nervous system to respond with love and kindness.
