KIDNEY 4

From Tang Zonghai, A Refined Interpretation of the Medical Classics (Yijing Jingyi), Qing Dynasty:

The root of the triple burner is in the kidney, more precisely right between the two anatomical kidneys. Right there is a greasy membrane that is connected with the spine. It is called mingmen, and constitutes the source of the three burners.

From Zhang Shanlei, A Revised Edition of Master Zhang's Treatise on the Organ Networks (Zhang Shi Zangfu Yaoshi Buzheng), ca. 1918:

The triple burner is really a name for the function of the body's ministerial fire. It is the process of disseminating original qi from mingmen, which is in charge of ascending and descending, and absorbing and excreting. It roams in between the heaven and earth of the body's landscape, and commands all bodily qi-the qi of the five zang and the six fu organs, the protective qi (wei) and the nutritive qi (ying), the qi in the channels and collaterals, and the qi on the top, the bottom, the left, and the right. Its unofficial name is therefore the central store house of clear qi. The upper part is in charge of absorbing, the middle part is in charge of transforming, and the lower part is in charge of excreting.

From Sun Yikui, Mysterious Pearls of Wisdom (Chi Shui Xuan Zhu), 1584:

The so called triple burner is embedded in the greasy membrane of the diaphragm, that is the hollow space between the five zang/six fu organs and the connective pathway through which food and grain must pass. The qi of the triple burner is contained and active within this space, steaming the diaphragm, reaching out to the skin, differentiating the flesh, and setting everything around it in motion. The regions that it reaches are labeled according to their location, that is why we speak of the upper burner, the middle burner, and the lower burner. Although the triple burner does not have any structural reality to it, it has a distinct location that is determined by the structural entities surrounding it.

From Shen Jin'ao, Illuminating Lantern on the Origins of Complex Diseases (Zabing Yuanliu Xizhu), 18th century:

What we call the triple burner is actually the corridor above and below the stomach. The triple burner and its associated regions thus entirely belong to the stomach, and what it oversees is primarily the functioning of the stomach. The triple burner qi is utilized to ferment and cook the food. Together with the stomach, the triple burner is located in front of the taiyin spleen network-a place that the roaming ministerial fire calls home. The term "burner," therefore, refers to the triple burner's function of cooking everything.

From Li Dongyuan, Illuminating the Science of Medicine (Yixue Faming), 13th century:

The triple burner is an entity that has a name but no structural form. It is in charge of all bodily qi, and it is a functional manifestation of the three treasures [jing, qi, shen]. All of the body's physiological movements, its unobstructed ins and outs and ups and downs, therefore, rely on the triple burner-the process of breathing in and breathing out, the ascending and descending motion of qi, and the absorption and excretion of food and water. The upper burner is located underneath the heart; it is in charge of storing without draining. The middle burner is in the center of the epigastric region; it is in charge of fermenting and cooking food and water. The lower burner is beneath the umbilicus; it is in charge of differentiating the clear from the turbid, and it drains without storing. The driving source behind all three of these functions, however, is the middle burner.

From Chen Nianzu, The Three Character Classic of Medicine (Yixue Sanzi Jing), Qing Dynasty:

The term triple burner refers to the qi that circulates in the upper, middle, and lower burners. Burner means heat. Only when the entire body cavity is permeated with hot qi can the body's water ways be open and regulated. The triple burner is the fu organ that forms a zang/fu pair with the pericardium, and thus belongs to the phase element fire. In other words, if the heating qualities of the upper burner are out of control, water will assault the upper plains of the body. If the middle burner is out of control, water will stagnate in the epigastric region. If the lower burner is out of control, water will disturb bowel movements and urination. On the other hand, if the triple burner qi is healthy and in control, the body's channels and collaterals will be open and its water ways will be disinhibited. It is for this reason that the triple burner is called the official in charge of uninhibited water flow.
