In Japanese temples, dragons are painted on ceilings to protect the law and summon sacred rain. It may not be a coincidence that I felt a dragon upon the roof of this hall. The ridges, like overlapping scales along its back, divert wind and shed rain, bringing it closer to the form of a dragon. Dragons bring nourishing rain and evade fire; the illusion of a dragon dwelling upon a roof sometimes takes on a striking sense of reality.
