In the old society thousands of years ago, there was no modern communication, no sufficient material supply, neither any good nor enough life supplies during the war years. The mere problem of water resources for survival in the wild for armies was a matter of the survival of not only the army but also the country.
But, in those ancient times, Taoists understood the breathing and circulatory system of Mother Earth, and they had very clever ways to determine the source of groundwater in those wild areas.
In ancient China, when marching and fighting, thousands of troops traveled long distances and carried large amounts of wormwood. Especially when they were in the northwest plateau and desert, they would first dig a huge deep hole, burn wormwood at the bottom of the hole, and observe the distant surroundings. After a while, they could see smoke coming out of other places. Then they dug deep at that smoking place, they knew they would definitely get water.
Why is it wormwood? How did the ancestors discover this? It is related to the knowledge of Chinese herbal medicine.
In ancient times, some great sorcerers had magical powers. Shen Nong tasted over a hundred grasses and picked out wormwood for some special body disease and pain treatment.
Taoism and Chinese pharmacology describe wormwood as ventilating. After the mugwort ignited, it sends out the warmth and penetrating. This warmth does not hurt, it is like a mother’s love.
This is the reason why moxibustion uses wormwood wool. Ancestors also discovered that the heat generated by the burning air of wormwood has the ability to travel through “spaces” both in the body of Mother Earth and in the body of humans. In the human body, it can carry heat energy to the “space” blocked by Yin Qi, and slowly dissolve the blockage. As a result, the Qi is ventilated, and the blood circulation is smoothened.
In Mother Earth’s body, they know the Qi and water circulation are inseparable like twin brothers, where the Qi reaches, where the water circulation arrives. Like mother, like children, because the human body has exactly the same energy Qi and Blood system as our Mother Earth.
Now, modern science is able to experiment that after the mugwort is ignited, its Qi can resonate harmonically with the human’s Qi, and its wavelength is the closest to the human body so that the human body can easily accept it, allowing the moxibustion Qi to penetrate deeper.
Why do we always call Qi and Blood together? It is because they are inseparable from each other. Where should this bring us to if we try to understand our Mother Earth’s Qi and Blood, our Mother Earth’s air breath, and water circulation? How this is related to climate change and environmental issues?
