Stilling the Mind

Let the Void be your cauldron.
Let Nature be your furnace.
For your primary ingredient, take stillness.
For your reagent; use quietude.
For Mercury, take your vital essence.
For Lead, use your vital energy.
For Water, use restraint.
For Fire, take meditation.

When the Mind is Stilled,
Spirit Brightens.
Great Mysteries are Illuminated.
- Chao Pi Chen

"The Triple Equation of Essence, Energy and Spirit unites to form the Golden Elixir of Immortality during deep meditation. According to Master Chao Pi Chen, the generative force changes into vitality when the body is still; vitality changes into spirit when the heart is unstirred; and spirit returns to nothingness because of immutable thought. The Elixir Field (Dantien) under the navel is where the generative force [essence] is sublimated into vitality [energy]; the middle Elixir Field in the solar plexus (Middle Dantien) is where vitality is sublimated into spirit; and the upper Elixir Field in the brain (Upper Dantien) is where spirit is sublimated for its flight into space."
