We have no reason to harbor any mistrust against our world, for it is not against us. If it has terrors, they are our terrors; if it has abysses, these abysses belong to us; if there are dangers, we must try to love them. And if only we arrange our life in accordance with the principle which tells us that we must always trust in the difficult, then what now appears to us as the most alien will become our most intimate and trusted experience.
