You cannot know who you unless you know what world is yours. You are apt for many worlds and each one returns a role, every such world being also a story. You can enter any story as easily as you can leave it. This can lead to endless confusion unless what you are is the very world that you find yourself in. And because without knowing who you are you know without any doubt that the knowledge of what you are is already in place, and that place can only be your world and inclusive of all worlds and of all who dwell therein.
