A hossu (払子) is a short staff of wood or bamboo with bundled hair (of a cow, horse, or yak) or hemp wielded by a Zen Buddhist priest.[1] Often described as a "fly swatter" or "fly shooer", the stick is believed to protect the wielder from desire and also works as a way of ridding areas of flies without killing them.[2] The hossu is regarded as symbolic of a Zen master's authority to teach and transmit Buddha Dharma to others, and is frequently passed from one master to the next.[3]
