White Tiger of the Heart: “Take the filled heart inside Kan to transform the yin in the belly of the Li Palace.”

When the blood cake (Xue Bing) is swallowed to go downward, the blue pupils disperse. [16] This is a post heaven event. On the palate there is an acu-point and under the tongue there are two acu-points that produce body fluids (Jin Ye), a treasure of the human body. Saliva goes down 1.2 cun under the heart to the Jiang Gong (Crimson Palace) at the root of the liver and becomes blood. When blood descends 1.3 cun below the navel it changes into Qi.....

 The “blood cake” represents the residual fluids from the umbilicus that, when cleared from the mouth immediately after birth, signal the start of Post-Natal, (Post-Heaven) life, which is characterized by respiration. The Du and Ren channels now can only be connected by the tongue touching the upper palate. This passage also mentions that in the transition from Pre-Heaven (before birth) to Post-Heaven, a baby’s eyes change color from blue to brown (or another color).

 The dark is Heaven, and in humans, forms the nose. The female is Earth and forms the mouth. Through the nose, the breath, and the five atmospheres associated with Heaven enter and form the Hun (“spiritual Soul; ethereal Soul). Through the mouth the five tastes enter and nourish the stomach and form the Po (the corporeal soul). The gates of the dark one and of the female are therefore the gates through which the original breath flows.

 Black Lead—the Water Tiger—is the root of the emission and development of Heaven and Earth.
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.

That which has substance is True Lead.
Ultimate Yin is the essence of the moon.
It is the mother that nurtures the form of Heaven, Earth, and the 10,000 Things.
That which is without substance is True Mercury.
Ultimate Yang is the brilliance of the sun.
It is the father that emits and causes the development of Heaven, Earth and the 10,000 Things.
The substance (ti ) of lead and mercury nurture one another and reproduce in profusion,350 cycling without cease.
It can be said to be the ancestor that produces Heaven, Earth and the 10,000 Things.

Establish the cauldron, then lead [the Essence of Ultimate Yin] to meet Ultimate Yang Qi.
Return them to the Spirit Room,353 where they wantonly (hun hun ) copulate.
Their copulation does not cease; their productive capability is inexhaustible.
The whitesoul is produced in the Wood [i.e., the liver]; the cloudsoul is born in Metal [i.e., the lungs].
The whitesoul and the cloudsoul congeal naturally.
This transforms and becomes the body.354
The copulation results in one hundred treasures.
It is named “Golden Liquid Reverted Elixir.”

 The position of Qian is the cauldron. The position of Kun is the furnace.371 Inside the cauldron is the yin of aqueous silver, which is to say the fire dragon-innate disposition root. Inside the furnace is the yang of the Jade Bud, which is to say the water tiger- lifespan stem. The tiger is below in order to emit the trigger of fire. The dragon resides above, setting the clouds off in a blustering storm. Just as the yang in the furnace ascends, yin invariably descends, then the celestial cloudsouls and terrestrial whitesouls in the cauldron preserve their tranformations. The Green Dragon and the White Tiger contain one another

 People of the world do not understand the procreative work of this dragon. Each suffer its harm. If people understand and fear it, look after it and control it, and they can subdue this hideous and ferocious dragon, then amass the utmost essence of mercury.412 Those who have subdued it control the true fire in the heart-mind. When the disposition of fire does not flare, then the dragon can be controlled and possessed. One can then obtain the time of lead. Therefore it is said: “If you don’t amass mercury, how can you seek lead? If you don’t subdue the dragon, how can you tame its tiger?” Both true lead and true mercury are not easily brought to bear. It is also difficult to tame the true tiger and force the true dragon to submit. If those who study the Dao can understand this one word then all their affairs will become minor concerns.

 Heaven (3) produces wood, which resides in the East Its manifestation is a green dragon
Earth (2) produces fire, which resides in the South Its manifestation is a vermillion bird
Heaven (1) produces water, which resides in the North Its manifestation is the Dark Warrior
Earth (4) produces metal, which resides in the West

Its manifestation is a white tiger

The tiger resides in the North, in Kan-water, but the yang line in Kan originally belonged in Qian.

 The dragon resides in the South, in Li-fire, but the yin line in Li originally belonged to Kun. After the downfall of primordial chaos because Kun received procreation and birth it paired with Qian. The middle line in Kun was filled and became Kan.

  “Take the filled heart inside Kan to transform the yin in the belly of the Li Palace.”

 So Li is yang and resides in the South. Because its outside is yang its inside yin, it is called “True Mercury.” Kan is yin and resides in the North. Because its outside is yin and its inside yang, it is called “True Lead.” For this reason, the Perfected Purple Yang said: “The sun, which resides in the Li position, returned, is woman. Kan resides in the Toad Palace,503 yet is man.”504 That is to say Kan is man and Li is woman, just like: father is essence, mother is blood,
