But their bodies are very frail. They do not eat earthly food; they have no weight or heat; they can cross water without making a splash, and they cast no shadow; they move as if floating, and some can even fly or pass through walls.
然而他們在形體的機能上卻非常微弱，他們不吃人間的食物；沒有重量、體溫，渡水無聲，沒有影子；走路輕飄飄的，甚至能飛天遁地、穿牆而過。
