《庄子·内篇·齐物论》中寓意深刻地说“:注焉而不满,酌焉而不竭,而不知其所由来,此之谓葆光。”其意是说,无论注入多少东西,它不会满盈;无论取出多少东西,它也不会枯竭,而且也不知这些东西出自哪里,这就叫作潜藏不露的光亮。什么东西注而不满,取而不竭呢?答案很简单人心。一个人心中的欲望是无限的,是怎么填都填不满的。反过来说,只有当心中满足,就不需要在身外求什么了。 The implication in the book “Zhuangzi · Internal Qiwu theory” is profoundly stated: "It does not matter how much you inject, but you do not know where you are. It does not get full, it does not dry up no matter how many things it takes, and it does not know where it came from, which is called the hidden light. What is not annoying note, but inexhaustible? The answer is simple. The desire of a person's heart is infinite, how to fill all the unsatisfied. Conversely, you do not need to seek anything out of your body until you are satisfied with your heart.
