The Zen Monk Kyō Has Changed His Name to Mujū Dōryū. I Wrote This Verse to Celebrate The Great Prospects That Lie Before HimUnwillingness to remain in the ruts of former Buddha patriarchs Unsurpassed aspiration and fierce passion to achieve the Way These are precisely the qualities found in a true Zen monk Attained the very moment you have been there and back.
