-『素問』陰陽應象大論篇第五。
「九竅」とは、人体にある9つの穴のことで、目、耳、鼻、口、前陰、肛門のことです。そして、「水注ぐの氣」とは、 水分（食べ物）から発生した氣のことで、いわゆる後天の氣を指しています。穴は外部と繋がる場所で、氣の通り道でもあります。よって、九竅はその氣に引かれた水分が注ぐ場所となっています。
たとえば、お鍋に水を入れてこれを火にかけたとします。熱せられた水は温度が上がり、湯気が発生します。この湯気がまさに水中の氣で、その氣がどこかに触れると結露します。これがまさに「水注ぐの氣」です。

“The nine orifices are the qi of pouring water.”– “Somon” Yin-Yang-Osho-Taron Volume 5.
The “nine orifices” refer to the nine openings in the human body: the eyes, ears, nose, mouth, anus, and anus. The “water-pouring Qi” refers to the Qi generated from water (food), or what is known as acquired Qi. Openings are places that connect to the outside world and are also pathways for Qi. Therefore, the nine orifices are the places where the water drawn by that Qi pours out.
For example, imagine you put water in a pot and put it on the fire. The heated water rises in temperature and steam is generated. This steam is the qi in the water, and when this qi comes into contact with something, it condenses. This is exactly the “qi of pouring water.”
