the purpose of life, is a life of purpose

we have not even to risk the adventure alone, for the heroes of all time have gone before. The labyrinth is thoroughly known. We have only to follow the thread of the hero path, and where we had thought to find an abomination, we shall find God. And where we had thought to slay another we shall slay ourselves. Where we had thought to travel outward, we will come to the centre of our own existence. And where we had thought to be alone we will be with all the world
