We are all social animals. Existence is co-existence. Even if we choose to live our lives as a hermit far away in a cave, in isolation, it is a social choice we make, a relationship we have with society. Most conflict that we experience happens in relation to other people. Being in social conflict is a physiological event. Fear and anger are physiological events. Everything is a physiological event. Likewise, being in social harmony is a physiological event. Love, kindness, empathy, joy are also physiological events. How we are physiologically, when in the presence of others, can dramatically influence, for better or worse, how we feel about others, and how they feel about us. Peace is a physiological event.
