“But the worst enemy you can meet will always be yourself; you lie in   wait for yourself in caverns and forests. Lonely one, you are going the   way to yourself! And your way goes past yourself, and past your seven   devils! You will be a heretic to yourself and witch and soothsayer and   fool and doubter and unholy one and villain. You must be ready to burn   yourself in your own flame: how could you become new, if you had not   first become ashes?”
