At the temple a monk retrieved something from a closet. As he went to replace it, the stool was positioned beneath the doorframe, and so with this arms reaching for a top shelf, and ascending the stool, he hit his head squarely on the frame.
He groaned. He walked the hard-wood floors as he rubbed the top of his head. It was that spot directly at the center.
Another monk walking the opposite direction asked him what was wrong. He said nothing was wrong while thinking bad thoughts. He said nothing was wrong but the pain was there.
He wandered outside and watched the monks sweep. Whereas before he felt serenity, now he felt agitation, a dizzy drop at the bottom of a bowl (he could not empty).
