《黄帝内经·灵枢·九针十二原》
如果五脏之气已绝于内，是阴虚，而用针反补在外的阳经，造成阳过盛而阴更虚，这叫重竭，重竭必死，其死时是安静的。
五脏之气已绝于内，而用针者反实其外，是谓重竭。重竭必死，其死也静。
If the qi of the five viscera is already exhausted internally, which is yin deficiency syndrome, and acupuncture is performed to supplement the yang channel, it will cause yang excess syndrome and further yin deficiency, which is called excessive exhaustion. If there is excessive exhaustion, it will lead to death, and a person will die peacefully at that time.
