Dual Cultivation of Nature & Life · Daoist Alchemy · Heart Sutra

The Practice

Changsheng Gong: Longmen alchemy for life, Heart Sutra for nature-of-mind.

Dual cultivation of nature & life

“Nature” means clarity of mind; “life” means healthy form and qi. One-sided practice tends toward empty quietism or fixation on the body. Dual cultivation is the stable path.

Our ming practice draws on Longmen Daoist alchemy: breath regulation, foundation building, opening Ren and Du, and running the Small Heavenly Circulation so qi can flow and self-repair.

Our xing practice follows the Heart Sutra: seeing the five aggregates as empty, the mind without obstruction, without fear, far from inverted dreams.

Nan Huai-Chin notes that Chan and Daoism can illuminate each other on mind-nature and form-qi. We take that as an orthodox cultural foundation—not personal deification.

Daoism refines form and qi to fulfill life; Chan points directly to mind-nature to fulfill nature. Nature and life need each other for completion.

Ming practice · Alchemy stages

A strength of this school is how quickly one can feel qi, open Ren and Du, and circulate the Small Orbit.

  1. 01

    1. Align body & breath

    Soften shoulders and waist; let breath return to the root. Settle the body, then refine the breath until qi becomes perceptible.

  2. 02

    2. Guard the dantian · hundred-day foundation

    Rest attention lightly in the lower dantian. Foundation work nourishes original qi—do not rush visions. The Secret of the Golden Flower is clear: without foundation, do not force the orbit.

  3. 03

    3. Open Ren & Du

    As qi ripens, the Du may rise and the Ren descend. Once open, qi has a path—like a river whose gate is lifted.

  4. 04

    4. Small Heavenly Circulation

    Qi rises with Du and descends with Ren, again and again. This is not hard mental pushing; it arrives when channels are ready. Many feel self-repair begin here.

  5. 05

    5. Qi nourishes the whole body

    With the orbit open, qi can nourish organs and meridians. “Discharge reactions” are common cleaning processes—learn what is normal and what needs a doctor.

About discharge / healing reactions

  • Common: short fatigue, ache at old injury sites, mood waves, deeper sleep or more dreams. Often eases with rest and lighter practice.
  • Response: slow down, drink warm water, sleep well; do not add intensity during strong reactions.
  • Seek care: high fever, severe pain, breathing trouble, altered awareness, bleeding, or sharp worsening of chronic illness—stop and get professional help.

Xing practice · Heart Sutra contemplation

Ming moves qi; xing sees through clinging. Together, the mind settles and qi steadies.

  • Observing at ease: Buddhism calls it observing the mind; Daoism calls it inner observation; the Secret of the Golden Flower says that what the sages have passed down, sage to sage, never departs from turning the light back. Buddhism cultivates calming and insight together—that is, concentration and wisdom.
  • Seeing the five aggregates as empty: the Laṅkāvatāra Sūtra says one should know that the person, the aggregates, the elements, and all conditions are empty, without self-nature. Form, feeling, perception, formations, and consciousness are all deluded thought—arising from conditions, empty in nature.
  • Śāriputra, all dharmas are marked by emptiness—not born, not destroyed, not stained, not pure, not increasing, not decreasing: what Chan calls illuminating the mind and seeing one’s nature, Daoism calls the primordial spirit returning to its seat.

Returning the light, guarding the center

Once seated, gather the gaze inward—not by staring hard, but by gently reclaiming outward-roaming spirit.

When breath is even, rest the heart in the center (or dantian). Neither chase thoughts nor fight them—simply know.

This is where the Golden Flower’s “return the light and guard the center” meets the Heart Sutra’s “observing at ease”: light does not flee outward; the mind does not seek outside.

Heart Sutra — text & plain English

Avalokiteśvara Bodhisattva, when practicing deeply the Prajñāpāramitā, saw the five aggregates as empty and crossed beyond all suffering.

In deep wisdom, the bodhisattva sees form, feeling, perception, formations, and consciousness as empty—and thus passes beyond suffering.

Form is not other than emptiness; emptiness is not other than form. Feeling, perception, formations, and consciousness are likewise.

Matter and emptiness are not two; the same is true of the other aggregates.

All dharmas are marked by emptiness: not born, not destroyed, not stained, not pure, not increasing, not decreasing.

Emptiness is originally beyond birth and death, purity and defilement, gain and loss.

In emptiness there is no form, no aggregates; no eyes, ears, nose, tongue, body, mind; no sights, sounds, smells, tastes, touches, dharmas; no eye-realm up to no mind-consciousness realm.

In emptiness, sense bases and sense objects are not clung to as ultimately real.

No ignorance and no ending of ignorance, up to no aging-and-death and no ending of aging-and-death; no suffering, arising, cessation, path; no wisdom and no attainment.

Even dependent arising and the four truths are not seized; wisdom and attainment are not seized.

With nothing to attain, bodhisattvas rely on Prajñāpāramitā; the mind is without obstruction. Without obstruction, there is no fear; far from inverted dreams, they realize nirvana.

Because nothing is grasped, the mind is free of obstruction and fear, and settles in liberation.

All Buddhas of the three times rely on Prajñāpāramitā and attain complete awakening. Know this prajñā as the great bright mantra that truly relieves all suffering.

Buddhas awaken by this wisdom; it truly relieves suffering.

Gate gate pāragate pārasaṃgate bodhi svāhā.

Gone, gone, gone beyond, gone altogether beyond—awakening, fulfilled.

01 Heavenly Heart

The heavenly heart is the pivot; outward, it scatters; inward, it gathers.

02 Primordial & Discriminating Spirit

Distinguish clear yuan-shen from clinging shi-shen; turn recognition back to the origin.

03 Return Light, Guard Center

Do not cast the light outward; guarding the center is the Golden Flower’s entry.

04 Return Light & Regulate Breath

Returning light and refining breath support each other; fine breath gathers spirit.

05 Errors in Returning Light

Ease of heart softens qi.

09 Hundred-Day Foundation

10 Nature-Light & Consciousness-Light

Discern true nature-light from clever consciousness-light.

12 The Orbit

Heavenly circulation joins Ren and Du in orderly flow.

13 Exhortation Song

Practice in daily life; do not leave human ethics behind.

Daily practice

Designed for desk-bound engineers: short, steady, sustainable.

Morning · 20 min standing & breath

Stand after waking, soften knees and waist, fine breath to the dantian. Seek clarity, not intensity.

Evening · 20 min sitting, return the light

Before sleep, gather the gaze inward, rest the heart in the center; recite a Heart Sutra line or simply abide with breath.

At work · three soft breaths

Each hour, stand, soften the waist, roll the shoulders, and take three long fine breaths into the lower abdomen.

Keys & cautions

Orthodox practice values steadiness over spectacular signs.

Do not force intention

Attention should be light. Heavy pushing stagnates qi and can cause chest tightness or head pressure.

Do not chase visions

Lights and sounds may appear—let them pass. Do not take illusions as proof.

Not after heavy meals or alcohol

Avoid practice within an hour of a full meal or after drinking. During menstruation or after surgery, reduce or pause—follow medical advice.

In strong emotion, regulate breath first

After rage or deep grief, even the breath before deciding to sit.
