“Secret of the Golden Flower” is a brilliant chinese alchemical text, and I am going to explain some of the principles mentioned within it. What it calls the Heavenly Heart refers to the pineal gland, or the third eye. This is an electro-magnetic navigator. It is connected to undistorted space-time signalry, which is the 4th dimension. The 3rd dimension is actually the product of space-time distortion; the space-time itself exists, in non-distorted form, in a 4th dimension. The 4th dimension consists of the inter-play of the pure elements of reality, without distortion. 3rd dimensional reality consists entirely of the distortion of these signals by the interplay of electro-magnetic forces between 3-dimensional bodies. In “Secret of the Golden Flower,” a text on Chinese Alchemy, the pineal gland, or third eye, is called the Heavenly Heart. It is further called seed-water, eros.

When space-time creatively expresses itself in 3-dimensional space, a dichotomy is created. One manifestation of this dichotomy is between anima and animus. Animus is the masculine principle, of heaven. Anima is the feminine principle, of earth. The anima is the substrate of form. She is the essence of change itself, and is found within the body.

The pineal gland is related to the eyes. The eyes are like emissaries for the third-eye. The eyes, as pineal emissaries, are designed to specifically tune in to a defined range of electro-magnetic signals. The pineal gland, being in touch with the periodic cycles of the elements, is able to take in information from this limited band-width and sort it according to these patterns, which are found everywhere, at all scales. This ‘Heavenly Heart’ is the dwelling of the animus. The animus lives in the eyes during the day, and is what allows us to see. At night, it is what gives us our dreams.

There is an energy center inside of your stomach about an inch inside. This is sometimes called the tan t’ien, in Zen and other schools. “Secret of the Golden Flower”  calls this thought-earth, the Heavenly Heart of the middle house. This is the house of wu wei, effortless effort, doing without doing. It is the energy-center of intuition. The dwelling place of the anima is in the heart, called ‘the lower heart’ in chinese alchemy. Here is the energy-center of our desire, of our raw passions and emotions. It is here where our bare humanity lies. In your throat is the energy center for self-expression and creativity. This is called spirit-fire, and it is the light, the logos, or the word.

The basic method is circulating light and energy through the pineal gland, through which one gains mastery of the anima, which is the principle of limitation. From Secret of the Golden Flower, “If this method is followed, plenty of seed-water will be present of itself; the spirit-fire will be ignited, and the thought-earth will solidify and crystallize. And thus can the holy fruit mature.”
The meaning is this.
‘Plenty of seed-water will be present of itself”: Through circulating light and energy through the pineal gland, you will naturally be in tune with the patterns of reality. You’ll be in harmony with the Universe.
“The spirit-fire will be ignited”: You will gain touch with the essence of true creativity. Self-expression will flow through you, as if you are a conduit for the energies of the Universe-at-large.
“The thought-earth will solidify and crystallize”: Your very instincts will begin to function according to the patterns of the Universe. Therefore, you will have succeeded in bringing undistorted ‘heavenly’ signals, or elements of 4th-dimensional space-time, into this very physical world.
