Two prohibitions, given together as a standing safety rule.
"Just as you should never hold on to your chi, you should never try to block or cut off any chi channel circulations during cultivation. You never try to cut off circulatory routes for the chi."1
Never hold. Retaining chi in a place, gripping it, keeping it.
Never block. Closing a route, damming a flow, stopping a circulation.
They are the same error in two forms — both are interference with movement, and movement is what the entire process consists of.
And the consequence is put in the strongest terms available: blocking a channel "would be like amputating an arm."1
Which sets the scale. Not a mistake that slows you down — a mutilation.
The justification is functional rather than doctrinal.
"All your chi channels should open and remain opened because they all exist for a reason."1
With the comparison made explicit: "just as all your nerves, lymph channels, veins and arteries exist for their own specific functions."2
No channel is spare. There is no redundant route, no circulation you could close without losing what it does — and the whole direction of the work is toward more open, never toward selectively closing.
Which is why the goal is stated as open and remain open. Not opened once; kept open. Anything that reverses that is working against the process, however clever the reason for it.
It also rules out a whole class of technique that practitioners reach for: closing one route to force pressure into another. On this account there is no such move available. See Hydraulic Loops, Not Mystical Anatomy.
There is a distinction here that keeps the rule from being paralysing.
Hercules fills the river Strymon with rocks and suffers no harm from it — so whatever he did, it was not closing a channel. The reading offered:
"Hercules only reduces the chi flow or current of the river Strymon, which also means he reduces the current of thoughts or predispositions in a certain direction."1
Reduction of a current is normal and safe. Severance is not.
Which maps onto something a practitioner can recognise: a compulsion losing force is a reduction; an urge being clamped shut is a blockage. The first is what happens as the work proceeds. The second is something you do.
The stated content of the reduction: "a reduction in mental afflictions or sexual desire, but as to the specifics, once again we cannot know for sure."1
The description of the outcome is the useful part, because it tells you what to look for.
"It shows that he is no longer controlled by certain chi flows driving him to do this or that. He has surmounted or transcended those impulses."3
Not gone. Not resisted. No longer controlling.
Which is a specific phenomenology and it is distinguishable from suppression. An impulse that has been clamped is still there and still pulling — you can feel the effort of holding it. An impulse whose current has been reduced simply does not move you, and there is nothing to hold.
Which is the same distinction that runs through the discipline material: a master refrains naturally, without force or strain, and the strained version closes something behind it. See Samadhi Is the Highest Discipline.
So the rule about channels and the rule about conduct are the same rule. Force applied to a flow closes something. Whether the flow is chi or an appetite makes no difference to the mechanics.
Set them side by side, because they produce identical behaviour and opposite interiors.
Suppression. The impulse arises at full strength. You hold it down. It takes effort, the effort is continuous, and on this account something closes behind it — a channel shut with hard rejection. The behaviour is correct and the cost is a blockage that later has to be reopened by the most difficult means available. See What Left-Hand Tantra Actually Is.
Transcendence. The current itself is weaker. The impulse arises and does not drive you. No effort is expended because nothing needed holding, and nothing closes.
Both look like abstinence from outside. Only one of them costs anything.
Which gives a usable self-test: ask what it took. An abstention that required force has, on this framework, produced exactly the kind of closure the rule prohibits — and you did it to yourself, without touching a channel deliberately at all.
That is the practical reach of the rule. It is not only about visualization techniques that dam a route. It covers how you handle your own appetites, which is where most people will actually break it.
Do not use techniques that close, dam or redirect a flow. If a method's mechanism is stop the chi going here so it goes there, it is the thing being warned against.
Do not hold chi anywhere. Retaining a sensation in a location — keeping the warmth in the belly, holding the pressure at a chakra — is the same error in its commonest form.
Let reductions happen; don't manufacture them. Currents weaken as the work proceeds. That is the process working. Trying to weaken one directly is force applied to a flow.
Watch what your restraint costs you. This is the version of the rule most people need: an appetite held down with a clench is a self-inflicted blockage. The target is the strength of the current, and it is not something you get at by gripping.
And if something is moving, let it move. Which is the same instruction as at every ejection and heat stage: don't assist, don't impede. See Maitreya's Big Knife Wind.
There is a named example of a whole tradition going wrong in exactly this way.
"Taoism degenerated into the school we see today in which nearly everyone is trying to open their channels by visualizing macrocosmic and microcosmic orbits while spinning their wind chi this way or that way and clinging to all the sensations."4
Three errors in one sentence, and they compound:
Directing the chi — spinning it this way or that — which is deliberate manipulation of a flow rather than letting it move.
Working the orbits as the practice — treating circulation routes as things to drive rather than things that open.
And clinging to the sensations — holding, which is the first prohibition.
Which is the whole rule broken in the ordinary course of what people think practice is. Nobody in that description believes they are blocking anything. They are being active with their chi, which feels like diligence, and is the error. See The Rotation Counts Are Fictitious.
The rule is inserted as a caution against a reading a practitioner might otherwise take home.
The river gets filled with rocks. If you read that as close the channel, you have a method — and it is the method that would injure you.
So the doctrine is used to constrain the reading rather than the reading to extend the doctrine: since blocking a channel is prohibited and Hercules is unharmed, the story cannot mean blocking. The safety rule wins, and the interpretation is bent to fit it.
Which is the right order of operations for anything read as instruction, and it is worth noting because the reverse is how symbolic material generally hurts people. A vivid image suggests a technique; the technique is harmful; the image gets followed anyway.
Evidence. [PRACTITIONER SOURCE]. 🚩 SINGLE SOURCE 🚩 SECONDARY WITHOUT PRIMARY. [SPECULATIVE] on the reading of the river; the prohibition itself is stated as doctrine.
Tension — reduce and block. The line between reducing a current and cutting it off is asserted rather than defined, and a practitioner has no way to know where reduction becomes closure.
Open question — what does the reduction? If you must not act on a current directly, what weakens it? The implied answer is the general work, but it is never stated.
Open question — can a closed channel be reopened? The amputation comparison suggests permanence; everything else in the material about hard rejection closing channels suggests they can be opened later, painfully. Both are implied and neither is settled.
Two instructions about the same flows, and they need care to hold together.
Do nothing to your chi. Don't hold it, don't block it, don't spin it, don't direct it. Every active relationship with the flow is the error.
And put your attention places deliberately. Visualize the whole skeleton; concentrate on the neglected regions; where the mind goes the chi goes. Which is directing the chi, by the material's own mechanism.
The reconciliation is presumably that attention placed is not flow manipulated — you illuminate a region and the chi arrives, rather than pushing it there. But the difference is subtle, and the described Taoist failure is people who thought they were doing the first while doing the second.
The convergence is exact with every other non-interference instruction in the sequence: surrender at the Big Knife Wind, don't assist the ejections, release rather than hold every visualization.
The Bodily Repression Mechanism — psychology.
Repression is not purely mental. Unwanted impulses are held out of awareness by sustained physical means — chronic muscular tension, restricted breathing, patterns of holding that become postural and stop being noticed as effort at all.
Two findings bear.
The holding is continuous and costly. Keeping material down is not a single act but an ongoing expenditure, maintained in the body, drawing resources indefinitely.
And it does not remove the impulse. The drive remains at full strength; what changes is that it is opposed. Which is why repression is unstable, why it leaks, and why release produces such a large change relative to the effort of stopping.
Which is precisely the distinction this rule turns on. A suppressed appetite is a blocked channel — held shut, continuously, at cost, with the current behind it undiminished. A transcended one is a current that has actually weakened, and nothing is being held.
That is what makes no longer controlled by certain chi flows a testable description rather than a pious one. Ask whether there is anything to stop doing. If letting go of the effort would release something, you are repressing. If there is no effort to release, the current genuinely reduced.
And it explains the amputation language. The clinical picture of long-term repression is exactly a body organised around not-feeling — with the restriction becoming structural and eventually invisible to the person maintaining it. A channel you have held shut for twenty years is not something you are doing; it is something you have become, and that is a fair reading of what the warning means by amputation.
Practical form: the difference between a discipline and a repression is whether stopping the effort would change anything — and that question is answerable in a second, on any appetite you have.
What the source leaves undetermined is what actually reduces a current.
The rule forbids the direct route. You may not block, dam, hold or manipulate a flow — and suppression, on the reading above, is the same error applied to an appetite.
So the reduction has to come from somewhere else. And the material never says where.
Three candidates are available from the surrounding material and none is endorsed. The channels open, and an impulse loses force because the obstruction driving it is gone. The mind quiets, and the current has less to feed on. Or the reduction is a by-product of the whole process with no specific cause at all.
Which leaves a practitioner with an impulse that is currently driving them, a prohibition on doing anything about it directly, and no account of what would change it. The rule tells you what not to do and the mechanism is left blank — which is exactly the gap people fill with the spinning and the directing that the same passage condemns.
