When I placed all the sacrificial ingredients on the kuśa grass, the deer, when playing, would touch the grass with its teeth and thus pollute it. When I chastised the deer by pushing it away, it would immediately become fearful and sit down motionless, exactly like the son of a saintly person. Thus it would stop its play.
