《淮南子·精神训》
所以这样又可将胆配云，肺配气，肝配风，肾配雨，脾配雷，以此来与天地自然相参验伍配，而这当中心脏是主宰物。
故胆为云，肺力气，肝为风，肾为雨，脾为雷，以与天地相参也，而心为之主。
Therefore, we can again associate the gallbladder with the clouds, the lungs with the qi, the liver with the wind, the kidneys with the rain, and the spleen with thunder. In this way, we can examine and compare them in a complementary way with the natural world of heaven and earth. The heart is the ruler in all of this.
