《黄帝内经·素问·上古天真论》
其次有称为圣人的人，能够安处于天地自然的正常环境之中，顺从八风的活动规律，使自己的嗜欲同世俗社会相应，没有恼怒怨恨之情，行为不离开世俗的一般准则，穿着装饰普通纹采的衣服，举动也没有炫耀于世俗的地方，在外，他不使形体因为事物而劳累，在内，没有任何思想负担，以安静、愉快为目的，以悠然自得为满足，所以他的形体不益衰惫，精神不益耗散，寿命也可达到百岁左右。
其次有圣人者，处天地之和，从八风之理，适嗜欲于世俗之间，无恚嗔之心，行不欲离于世，被服章，举不欲观于俗，外不劳形于事，内无思想之患，以恬愉为务，以自得为功，形体不敝，精神不散，亦可以百数。

Externally, he does not let his body get tired because of things, internally, he does not have any ideological burden, takes quietness and happiness as the goal, and takes pleasure in taking things as they are, so his body does not decline, his spirit does not get lost, and his life span can also reach around one hundred years old.
