So citing Daniel Burton-Rose, Master's thesis, "Integrating Internal Alchemy...."
Black Lead—the Water Tiger—is the root of the emission and development of Heaven and Earth.So the Red Lead descends as a female - such that the normal yang of the upper body fire going out the eyes, is reversed, and so pursues its essence in the Jade (moon) brain.
Only then is there substance (zhi ) and qi.
Red Lead—the Fire Dragon—is the foundation of the emission and development of Heaven and Earth.
Only then is there qi and no substance.
What this really means is that the qi, joins up with jing, and then cycles up to the third eye as the copulation of dragon and tiger. The Water tiger is thereby turned into White Tiger and the Fire Dragon is thereby turned into Green Dragon (the right and left eyes respectively)...
The Moon in turn has to swallow the raven which means that the spirit of the heart has to go down into qi of the black lead, the Moon.
And so the spirit has to control the qi.
The raven is the girl or female as the yin mercury qi within the yang of the sun as spirit (heart). This is the Red Lead, the fire dragon. It is not "true lead" since it has no substance.
And yet it has to control the qi that does have substance.
The true lead has "silver" in it as the boy, as metal that shines - the qi in the water tiger. So it is governed by the lungs.
And so just as Heaven had to take from Earth in order to make Fire, so did Earth have to take from Heaven in order to make Water. And so alchemically this has to be reversed using wood and metal.
If the "cloudsoul" (the liver qi) descends then the heavier "whitesoul" (metal of lung) follows it - and this is the path of the sages - to purify the qi going down the front.
Since the cloudsoul is normally "lite and pure" then it normally ascends, causing the heavier soul to cling to it and follow it - and this is the path of common people.
The cloudsoul gives into Liver at night -but the whitesoul (the lungs qi) goes out of the eyes during the day!
O.K. I thought the liver qi went out of the eyes during the day! Wow. Oh I get it - the white soul is "pulled up" to the eyes by clinging to the liter, purer cloudsoul of the liver....
So "white soul" of the lungs refers to the white of the bones that stay in the urn at death.... - the corporeal po soul.
And so Earth's wuji - Void or Counter-Earth of Pythagorean alchemy - is the yin qi of the yang sun fire - the mercury as the yin of Earth - and the yang qi of the yin moon water is the Yang of Earth.
So they create the one qi of the yin-yang as the "vital qi" or yuan qi. while heaven is the yuan shen.
So the Wu-Earth is the tiger as yang qi and the Ji-Earth is dragon as the yin qi. Together they are the Yuan Qi.
Atemporal Qi is the dragon-tiger new moon qi.
And so now we turn to a PH.D. thesis - alchemical teachings of Chen Zhixu - William Clarke Hudson, now professor.
So for the 2nd time - the term "sun-hare" is used instead of "moon hare" - which is to say that there is tiger in the dragon and vice versa as well as moon in the sun and vice versa....
So that's what makes this so confusion - but at least now we figured out the yin and yang qi secret.
