反者道之动。弱者道之用。天下万物生于有,有生于无。
《老子》第40章
Constant reversal is the movement of the Tao,and being weak is the function of the Tao. AlI things under Heaven come into being from visible concrete beings,and all beings come into being from the invisible Tao.
[注释]
反:复也。王粥说:“复者,反本之谓也。”天下万物生于有,有生于无:有,存在的物质。无,虚无的空间,即“道”。
[译文]
向着相反的方向变化,是“道”的运行规律。保持着柔弱的状态,是“道”的作用。天下万物生于可见的具体事物,可见的具体事物都是从看不见的“道”中产生。
