2 The oil of lamp is worn out because it burns itself to illuminate other.
燈油被火燒盡，則是基於它燃燒自己照亮別人的特性。
3 Cassia bark is both traditional medicine and the trimmings for dish so its branches and bark are always cut off.
桂皮是中藥，也是燒菜的配料。因此，桂樹老是有截肢之痛。
4 The sap of varnish tree can be use to make lacquer so it is cut all the time.
漆樹的樹汁可以利用來造漆，因此漆樹老是有被割的遭遇。
5 We all know the use of thing but forget the subtle effects of uselessness.
我們都熟知物質可“用”的好處，但卻都忽略了物質“無用”的妙處。
山木，自寇也﹔膏火，自煎也。桂可食，故伐之﹔漆可用，故割之。人皆知有用之用，而莫知無用之用也。
