Nine elements, one posture, and four stages built on top of each other. This is the whole of what a practitioner does, gathered in one place rather than spread across seventy-two level entries.
The elements of a sitting
Taught in this order, and practised all at once. Every later level adds to what is here rather than replacing it — the sitting a practitioner does at the fourth level is the sitting they learned at the first.
Cross-legged on bare ground, the back unsupported. The crown is carried up, the pelvis rests on the earth, and the hands lie on the knees — thumb touching the index finger, palm upward. The attention stays in the lower field for the whole sitting.
1
The posture
Cross-legged on the floor, spine upright and unsupported.
Half lotus or full lotus, on the ground. In full lotus the hands rest palms up on the knees. In half lotus the thumb touches the index finger, palm up — a closed circuit, on the reasoning that what is being gathered should not run out at the extremities. The crown is carried upward, the pelvis sits on the floor, the spine is straight and the shoulders are loose.
The back is not supported: no chair back, no wall. The neck is aligned over the spine and the spine over the ming men, so that the whole column stacks rather than leans. Chang himself is described in the accounts as sitting on the floor.
Nothing about the posture is decorative. An upright unsupported spine is what allows the route of level 2 to be worked at all, and the cross-legged base is what makes the perineal lock below possible to hold for an hour. There is no stated alternative for anyone who cannot sit this way, which is a real gap: the pragmatic substitute used across the wider internal literature is an upright seat on the front edge of a hard chair, feet flat, spine free. It is not the lineage instruction, and this archive is not going to pretend that it is.

The ground
Direct contact with the earth, on the claim that half the work is drawn up through it.
The practitioner sits outside, on bare earth or on stone, with nothing synthetic in between — no foam mat, no rubber, no plastic-backed cushion. The stated reason is that yin qi is absorbed passively through contact at hui yin, and that an insulated seat cuts that half of the supply off entirely, leaving the practitioner accumulating one polarity and not the other.
Where sitting outdoors is impossible the improvised substitute is a conductor: a metal plate under the seat, wired to a water pipe or to a stake driven into the ground. The reasoning is electrical throughout — the body treated as something that has to be earthed before it can be charged.
This is the element the classical literature says least about and the modern instruction insists on most, and it is worth knowing that the emphasis is recent. What the older material describes is drawing from below; the wire and the ground stake are a twentieth-century reading of that instruction.

The lock
The perineum and anal sphincter are drawn up and held, for the whole sitting.
This is the single most consistently emphasised mechanical detail in the method, and the one that most distinguishes it from ordinary seated meditation. The perineal region — hui yin — is contracted and drawn upward, and held there throughout.
Its purpose is mechanical rather than symbolic: it seals the bottom of the vessel, so that what is being accumulated in the lower dan tien does not drain away between sessions. The tradition treats a practitioner who gathers without sealing as filling a bucket with a hole in it. At the later stages the same contraction is put to a second use — squeezed hard, under a held breath, to drive the accumulation downward.
It is also the detail most often overdone. Chronic over-contraction of the pelvic floor is a recognised cause of pelvic floor dysfunction, and the instruction says to hold the lock without ever saying how firmly. The common error is to recruit the buttocks and the abdominal wall instead of the pelvic floor alone, which tilts the pelvis, loads the lumbar spine, and produces the low back pain that so many practitioners report.

The breath
Abdominal, progressively slowed, and at some point reversed.
Breathing is abdominal — the belly moves, the chest does not. The shoulders staying still is the test: a breath carried high in the chest leaves what is gathered high in the body, where it is not wanted. In through the nose, out through the mouth, and slowing over months rather than days: eight breaths a minute, then seven, six, five, four, and eventually one or two, which is the rate associated with the depth of stillness the method asks for.
After the first couple of months the mechanism reverses. In reverse breathing the abdomen draws in on the inhalation and expands on the exhalation — the opposite of ordinary practice — with the tongue raised to the palate on the way in and lowered on the way out. It is awkward at first and shortens the breath before it lengthens it.
Retention belongs to the later stages rather than the first, and this is where the greatest physical caution belongs. Prolonged breath retention produces hypoxia and hypercapnia and can end in syncope. Practised in or beside water, or while driving, it can kill — and it is precisely the practitioners furthest along, holding the breath while forcing pressure down into the abdomen, who are least likely to treat it as dangerous.
Ordinary abdominal breathing is learned first and reversed later: the belly draws in as the breath comes in. The rate falls over months, not days.

The state
The borderline between waking and sleeping — a precondition, not a by-product.
The sitting does very little outside a particular state of consciousness: the borderline between waking and sleeping, the body asleep and the mind awake and alert. It is the hardest part of the first level and the part most often skipped, and time spent sitting outside it is very largely time spent.
The method is unusually plain about what this is not. There is no mantra. There is no visualisation: qi is felt as a physical sensation with a location, not pictured as light or colour, and anything imagined is understood to be imagination. And there is a distinction drawn between meditation, which is a relaxed state one can think in, and concentration, which is a single fixed point with nothing else in it. An hour of the first may contain a minute of the second.
This is the part that defeats most people, and it is why the durations below are real requirements rather than targets. An hour of wandering attention is not an hour of practice.

6
The attention
Fixed on the lower dan tien, physically felt, for the entire session.
Attention rests on a point roughly three finger-widths below the navel and a little way inside the body — the lower dan tien. The focus is meant to be narrow: one point, held, not a general awareness of the abdomen. Beginners are told to put a hand on the spot at the start of a session to tell the mind where to go, and then take it away.
The whole of the technique is contained in one instruction, and it is the one classical practice would recognise: put the attention on the lower field, and when you notice it has gone, put it back. Attention, not intention — nothing is being pushed or steered at this stage, only attended to.
The first reported sign is heat in the lower abdomen, which builds over months and can become intense enough to be uncomfortable. A second sign follows, described as arriving for everyone but landing differently in different people.

7
The stillness
No movement at all — not to shift a leg, not to scratch.
The practitioner does not move during the sitting. The knee and back pain that follows is treated as part of the work rather than as a signal, and Chang is reported to have regarded a student who fidgeted as not practising.
Spontaneous trembling, jerking or rhythmic shaking is ordinary and is to be ignored rather than encouraged or suppressed. At the last of the stages below, absolute stillness stops being a discipline and becomes a safety requirement.
Immobility has its own cost, and it is the most predictable injury in the whole method. Hours of cross-legged sitting cause peroneal and sciatic nerve compression and joint injury; ankle and knee pain, low back pain, and a pinched sensation under the shoulder blade are all common. Numbness that persists after standing is an injury rather than a milestone.

8
The duration
An hour daily as the floor, rising with practice. Consistency counts for more than length.
One hour a day is the usual minimum, built up slowly — five minutes, then ten, adding a few at a time as the body adjusts. Reaching a comfortable hour can itself take a year or two, and a second daily session comes after that. Serious students sit two to four hours, and the later stages demand three hours a day and eventually most of it.
Totals are given in the thousands of hours rather than in months, and the figures vary enormously from one practitioner to the next: somewhere between a few hundred hours and several thousand to fill the lower field, and anywhere from one to seven years of daily sitting. Nobody can tell you in advance which of those you will be.
Lapses cost more than they appear to. The accumulation is described as leaking away when practice stops, so three sessions a week is not slower progress — the accounts treat it as no progress at all.

9
The continence
Sexual conservation, on stated mechanical grounds, with a seventy-two hour rule attached.
Continence, or at minimum strict conservation, is required. The reason given is not ethical: jing is held to be the raw material being converted into qi, and ejaculation spends it. A single lapse is said to cost weeks of accumulation.
Attached to it is the most specific rule in the method: after any emission, by any route including in sleep, training stops for seventy-two hours. Sitting inside that window is said to tear the lower dan tien and end the practice permanently, on the reasoning that a torn container cannot be filled.
A marked rise in sexual energy is itself among the ordinary signs of the first level, which is precisely the difficulty: the thing the practice produces is the thing that must not be spent. Worse, the same overheating that drives the rise also causes involuntary emission in sleep — so the rule is as often a trap as a discipline, and a practitioner can lose weeks to it without any lapse of will at all.

The curriculum, stage by stage
The stages are given in the order they are taught. Each one continues alongside the next rather than being replaced by it — a practitioner at the last stage is still doing the first every day.
Level 1
Filling the lower dan tien
Accumulate qi in the lower dan tien until the mass is dense enough to be felt from outside the body.
Sitting, grounded, half or full lotus, for an hour a day and upward. Attention on the lower field, in the borderline state, with the breath slowing over months and reversing after the first couple of them. Nothing is added and nothing else is done: this level is the method, and every stage after it is built on top of it and continues alongside it rather than replacing it.
Reported signs
Heat in the lower abdomen is the first, building over many months. A second follows. The accumulation is eventually said to be dense enough that another person can feel it, about two finger-widths inside the abdominal wall.
Time given
A few hundred to several thousand hours of sitting — one to seven years of daily practice, with wide variation between individuals.
This is the level almost everyone stops at, and the only one that can be practised indefinitely without the risks that follow. On its own it is a slow, conservative concentration practice.
Level 2a
Condensing the accumulation
Compress what was gathered into a dense mass, and open a route from the lower field to the palms.
A standing form, done in a horse stance, and hard qigong rather than seated work: dynamic muscular tension, a held breath, and the arms pushed out and drawn back under load. It belongs to the same family as the Iron Wire sets of southern kung fu, and it is trained the same way — few repetitions, maximum effort.
The breath carries the work. Inhale into the chest and hold; move the pressure down onto the lower dan tien and hold it there, like a press; bring it back up into the chest and out along the arms; then push the palms forward and release the breath slowly. The palms open half way as half the breath goes, and reach full extension as the last of it leaves.
The seated practice does not stop. It lengthens — toward three hours a day — in preparation for what follows. A practitioner who trades sitting for standing has misunderstood the level.
A horse stance, muscular tension, and a held breath released as the palms travel forward. The seated practice lengthens alongside this rather than being replaced by it.
Reported signs
The mass condenses from roughly the size of a marble to roughly the size of a golf ball, and grows no further. Strength and heat in the arms increase markedly.
Time given
Around a hundred repetitions a day. Far more than that is counter-productive, and the traditional total runs to tens of thousands of repetitions over years.
This is the stage at which most practitioners are injured, and the point at which the method stops resembling meditation. The hazards below are overwhelmingly hazards of this level and the ones after it.
Level 2b
Freeing the mass
Free the condensed mass from where it rests, so that it can be moved at will.
Seated, in full lotus, for most of the day with short breaks — the longest and most tedious stage in the system. The abdomen is drawn in, the breath held, and one arm at a time pushed out and pulled back under isometric tension, the palm turned slightly inward like a knife-hand, with the attention inside the mass rather than on the arm.
What is being worked on are the connective attachments that hold the mass in place. Parting them is what makes it mobile, and mobility is what the meeting at the last stage requires.
Condensing makes the mass dense; parting the cords makes it mobile; rotating it and driving it down prepares the meeting that follows. A sting that starts at the outer thumb and ends in the centre of the palm is the sign given for a cord parting.
Reported signs
A stinging, electric sensation that begins at the outer thumb joint and migrates, with practice, to the centre of the palm — and has to be produced in both palms. The mass can then be moved several inches in any direction, most importantly downward.
Time given
Longer than the condensing stage, because of the hours the sitting demands rather than the difficulty of the movement.
Blood in the urine has been reported on completing this stage. It is presented in the tradition as a sign; it is also a symptom that warrants a doctor.
Level 3
Moving the mass
Take full control of the mass — rotate it, drive it down to the perineum, and bring it back.
Seated on the ground. The chest and lungs are emptied, hui yin and the anus are squeezed, and the last of the breath is driven downward under hard pressure. The mass is rotated in place — twenty-four turns one way, twenty-four the other — then directed down to the perineum, warmed there, and drawn back up, repeated many times in a session.
By this stage the sitting occupies most of the day, and the work is entirely internal again: there is no external movement, only pressure, rotation and placement.
Reported signs
Free movement of the mass in any direction, and an unmistakable discharge sensation on contact with another body.
Time given
A long stage, and the last for which the method is described in any detail.
Forcing pressure downward against a closed glottis for extended periods is a Valsalva manoeuvre, repeated for hours. It raises intra-abdominal and intrathoracic pressure, spikes and then drops blood pressure, and is a recognised trigger for fainting, hernia and cardiac events.
Level 4
The meeting of yin and yang
Bring the stored yang and the yin gathered at the perineum together in one place.
Two operations, in order. First the yang is pushed down through hui yin and into the earth, and as much yin drawn back up as yang was sent down; the instruction given for the feeling is that the body sinks. Then yin is drawn up from the ground through hui yin, and yang down from the sky through bai hui, on the same inhalation, so the two arrive in the lower dan tien together and are held there.
This is the operation the published accounts call the marriage of yin and yang, and it is the point past which there is no methodical instruction left. Everything ever filmed belongs after it.
Drawn down through the crown, drawn up through the perineum, arriving together in the lower field and held there. A shock felt through the body is the sign given that the two have met.
Reported signs
An electric shock felt through the body as the two begin to meet, which then becomes the object of the meditation until the fusion completes.
Time given
Treated as an event rather than a gradual gain, and reached by very few.
This is the most dangerous point in the system by every account of it. Absolute stillness is a requirement rather than a discipline here, and the fusion is described as killing most of those who attempt it.
What goes wrong
The pattern of injury in this practice follows directly from what the practice does. Nei kung does not create qi. It takes it — from the whole body, and once any surplus is gone, from what the body was already using — and packs it into one place, while deliberately preventing the circulation that would ordinarily distribute it again. A method built on concentrating a limited resource and blocking its return produces deficiency everywhere it was drawn from, and that is what practitioners report.
Kidney depletion
The characteristic injury, and the one nearly every advanced practitioner reports some version of. In the frame this tradition uses, the "kidneys" take in the adrenals and the gonads, and they are the organ complex the practice draws hardest on. It shows as intolerance of cold, cold hands and feet, urinary frequency or incontinence, exhaustion, and loss of sexual function.
Depletion headaches
Common once serious compression begins, and comparable to the headache of sexual overexpenditure — the same deficiency, arriving by a different route. Persistent headache during this phase of training is a signal to stop, not a sign of progress.
Prostate obstruction and involuntary emission
Jing produced but never spent congests; overheating then forces it out anyway, in sleep, in urination, or during sex. That triggers the seventy-two hour rule, the practitioner rebuilds, overheats again, and the cycle repeats. Pelvic pain, urinary difficulty and prostatitis are all reported.
Deficiency of both yin and yang
The end state of that cycle — swinging from overheated to depleted until both are exhausted at once. It is the hardest of these conditions to correct, and the one most likely to persist long after the practice stops.
Cardiovascular strain
The later stages combine long breath retention with hard downward abdominal pressure — a sustained Valsalva manoeuvre. That raises then sharply drops blood pressure, and is associated with fainting, arrhythmia, hernia and, in people with unsuspected cardiac disease, worse.
Nerve compression and joint injury
The ordinary, entirely predictable cost of hours of immobile cross-legged sitting: compressed peroneal and sciatic nerves, damaged knees and hips, and the pinched nerve under the shoulder blade that comes from holding a standing form with the elbows wrongly placed. Numbness that outlasts the session is an injury.
Isolation
Not a physical injury, but the one that makes all the others worse. This is a practice done alone, for years, on instructions that cannot be checked, with progress measured by sensations only the practitioner can feel. It selects for people who will not stop when something is wrong, and it removes everyone who might tell them to.
Condense the accumulation, free it from where it rests, and drive it down to the coccyx and up the spine through the three gates.
The seated practice is unchanged and must lengthen. What is added is a standing form of hard qigong — muscular tension, held breath, and pressure driven down onto the lower field.
A further 1–3 years at minimum. This is the stage that stops most people.
Draw yang qi and unite it with the stored yin — the kan-li operation.
A change of orientation: attention that was entirely downward and inward now also opens upward. The method for drawing yang is the part of the curriculum withheld most carefully.
Send the fused qi outside the body, through the hands.
No new sitting method. What is new is expenditure — and everything ever filmed belongs here.
Chang is placed at level 4 at the 1988 filming, after roughly two decades.
Each level page carries the practice, the reported signs, the obstacles and how the level is said to be tested. Above level 4 the sources stop describing method — see the ladder for what remains.
