“How wonderful and pleasant it is to sit together as brothers.” These are friends who are sitting together, not parting from each other. At first, they seem to be people in enmity with each other and wanting to kill each other. But afterward, they return to brotherly love. And then they exclaim: “How wonderful and pleasant it is to sit together as brothers.” By doing this, they reach similarity to the integral system of nature and they correspond to it. And in their common love, they reveal the essence of nature, its perfection and eternity.
