In any city, in any country, go to any mental institution or halfway house you can get yourself into. When you reach the front desk, ask to visit someone who calls himself "The Holder of the Lens." The attendant will not acknowledge your request at first, but you must continue to ask. When she raises her head, she will give you a questioning look, and ask if you are sure. If you have any doubt in your mind that you will not succeed, turn away quietly and never return. If you have no doubt of your impending victory, then give her a single nod. She will smile softly and lead you through a door behind the desk.
