《淮南子·诠言训》
所以精神处于制约地位，形体就服从精神，如形体制约精神，精神就会耗尽。聪明虽然管用，但还必须返归到精神上来，达到这种虚静中和境界的叫做 太冲 。
故神制则形从，形胜则神穷，聪明虽用，必反诸神，谓之太冲。
That's why when the spirit is in control, the physical will submit. If the body controls the spirit, the spirit will be exhausted. Ingenuity is useful, but it must always return to the spirit. To reach that state of tranquility and balance is called "Tai Chong."
