Housebugs

Master Back Sung-wook was staying at a temple. One day a monk was worried about the housebugs in the main sanctuary and told it to him. Back Sungwook told him to burn sulfur there with the doors closed and that they would be cleared of, then. The monk got angry and said, "What ? Are you telling me to kill them ?" He smiled and answered, "Are you trying to decorate it with housebugs on the contrary ?"
