Gampopa comes out of retreat with something to report. His cave was full of Avalokiteśvaras, hundreds of them, each with a moon disc floating above the head. It's the sort of thing a tradition builds a shrine around.
His teacher's whole reply:
This is due to the increase of bindu [bodhimind substance, or jing] in the Great Bliss chakra at the crown of your head. It is neither good nor bad. Keep meditating.1
Not what a blessing, and not what does it mean. A substance, a location, and go back to work.
That's the claim this page carries. The bliss you feel in meditation — and the visions that ride on it — is what a particular chemical building up in a particular place feels like from the inside. Milarepa isn't being dismissive. He's naming the cause, the way a doctor names why your ears are ringing.
Meditate long enough and at some point you feel good. Not pleased — physically good. A sweetness that spreads up through the chest.
Bodri says that feeling is hormones.
He means it literally. Jing is the Chinese word for the body's basic vital stuff, the thing you're born with a fixed amount of and spend by living. Here it's defined as "the endocrine functions of the kidney glands and reproductive organ." The sweet saliva that shows up in these practices is defined as "the endocrine functions of the pituitary and lymph glands."4 Kidneys, gonads, pituitary, lymph. Those are glands.
So meditation changes your glands, and bliss is what that change feels like from inside: "Jing is paired with physical bliss because the body's hormonal system is responsible for producing the physical bliss generated in spiritual cultivation."2
The fuller version, four hundred pages on, adds the part that matters:
Jing and chi and shen transformations are the actual biophysical causes behind the states of physical bliss and mental joy you experience in the four dhyāna, and because they occur when the mind achieves certain degrees of emptiness, you get the co-joint, simultaneous attainment of the four empties and blisses.3
There are two different claims in there and they need keeping apart.
The first is a cause. Bliss comes from the jing–chi–shen conversion — raw physical stock becoming energy, energy becoming spirit — which on the identification above is your endocrine system running through a sequence.
The second is not a cause. Bliss and emptiness show up together "because they occur when the mind achieves certain degrees of emptiness." Emptiness doesn't feel like bliss and bliss isn't a small emptiness. They're two dials moved by one hand.
Which is why this isn't the deflating reading it sounds like. Nobody is saying the bliss is only chemical and therefore worthless. The bliss is real, it's necessary, and it isn't the thing you came for. It's the receipt, not the purchase.
Tsong Khapa gives the actual procedure: steps, in order, with one of them marked as non-negotiable.
You have three channels running up the trunk of the body: two side channels, rasana and lalana, and the central one, avadhūti. Ordinarily your energy runs up the two sides and the middle one stays shut. Everything below depends on getting it out of the sides and into the middle.
In general, all systems of highest yoga tantra's completion stage involve the preliminary process of controlling the vital energies flowing through the two side channels, rasana and lalana, and redirecting them into the central channel, avadhuti. This is indispensable.5
The method named for doing it is inner heat at the navel — tummo, the "wheel of emanation." You build heat there, and then you use the short AH syllable to draw the energy inward. When the energy actually enters the central channel, the four blisses arrive on their own. You meditate on that, and out of it comes the innate wisdom the system is aiming at.5
Underneath the heat there's a switch, and it's stated in a bracketed gloss that's easy to skim past. You work the wind element of the body to ignite the warmth element — and the warmth element "is only activated during the state of hsi, or respiratory cessation. All the transformations that come about are due to this state of hsi."5
That's the load-bearing sentence in the whole protocol. Hsi is what happens when the breath stops of its own accord — not held, not suppressed, just no longer needed for a while. Until that happens, the heat doesn't light. Until the heat lights, the energy doesn't move into the middle. Until it moves, no blisses. So a practitioner working on bliss without the breath having stopped is trying to light a fire in a sealed jar.
There's a marker for when it's working, and it's a physical one: training well in this "has the power to give control over loss of the bodhimind substance" — control over losing jing.5 Hormone conservation, in the vocabulary of the page. That's the checkable sign that the energy is going where it's meant to.
The tradition's own summary is four words — "the inner heat, the foundation" — and it means what it says. The heat comes in at the very beginning, and every later practice in the system is built on top of it.5
There's a way to get all of this wrong, and it's the one a good meditator falls into.
Sit in unbroken concentration, hour after hour, day after day, mind clear and pleasant and free of thoughts, and you can do that for years and go nowhere. The verdict: a samādhi "that merely maintains a state of non-conceptual absorption for a prolonged period of time" produces "no great signs of progress." The bracketed name for it is dry Zen, or dead Zen — "a stage of clear equanimity without the circulation of the vital force."5
The illustration is the first meeting between the two men in the hook. Gampopa, already an accomplished monk, mentions that he can sit in concentration for days at a stretch without a flicker of distraction. Milarepa's answer:
You cannot get oil by crushing sand. The practice of samadhi is not sufficient in and of itself. You should learn my system of inner heat yoga, which redirects the subtle life-sustaining energies into the AH-stroke mantric syllable.5
Crush sand as hard as you like — there was never any oil in it. The stillness isn't wrong and it isn't wasted. It just isn't the ingredient that makes the thing happen, and no amount of extra stillness turns into the ingredient you're missing.
So the requirement has two halves and you need both. Emptiness with no energy moving is dry Zen. Energy moving with no emptiness is the other failure, the one the next section is about. The four blisses and the four states of emptiness are described as "two oxen yoked as a pair" — they pull together or the cart doesn't move.5
The same authors' earlier book gives the drops an origin and a physical description, and both are more concrete than anything on this page so far. All of them are said to have evolved from the original white drop of the father and the red drop of the mother, contributed at conception.9 So the whole system runs on two substances that arrived before you did.
The description of where they sit is the good part. The drops run throughout the body and coat the inside of the chi channels like frost.9 Not pooled, not stored in an organ — a thin layer on the inner surface of everything, the way ice forms on the inside of a window. Which is what makes them meltable, and melting is the operation every one of these practices performs on them.
Two functions are assigned, and they're ordinary physiology rather than metaphysics. The white drops predominate at the top of the head and contribute to the development of protein. The red drops predominate at the solar plexus and contribute to the development of blood.9 The samādhi-and-bliss achievement is then tied to the balancing of hormones and blood, and to the balancing of consciousness and chi.
There's a set of four that maps drops onto states, and it covers the whole day rather than just the practice. Body drops are responsible for the waking state and abide in the head. Speech drops are responsible for dreaming and abide in the throat. Mind drops are responsible for deep sleep and abide at the heart. And there are the drops of sexual ecstasy, called the drops of the fourth occasion or exalted wisdom drops.9
Look at how the first three are arranged. Waking is highest, dreaming is in the middle, deep sleep is at the chest — the states descend as the locations descend, and the deeper the sleep the lower the seat. That's the same downward ordering the four blisses use, which is why focusing at the heart before sleep is the basis of the clear-light-of-sleep practices.
The fourth breaks the pattern and is given no location at all. It gets a different naming convention too — an occasion rather than a faculty, and exalted wisdom rather than body, speech or mind. What the tantric practices then do with all of this is stated plainly: the drops can be brought into the central channel, assembled at the heart chakra, and made into the basis of a purified subtle body.9
If bliss is what a hormonal shift feels like, then feeling bliss tells you a hormonal shift happened. That's all it tells you. It doesn't tell you what caused the shift.
And the same material lists plenty of things that shift the same glands and have nothing to do with getting anywhere: forcing your breath, visualising hard, drugs, illness, or the plain friction of a blocked channel finally grinding open. All of those feel wonderful. None of them is progress.
Milarepa's phrase does this job, and he uses it three times in three consecutive sessions: it is neither good nor bad.1 The bliss is real. It has a cause. The cause is mechanical. And none of that makes it a milestone.
Which is why the passage explaining the mechanism turns straight into a warning:
The major problem with this type of practice is that you are focusing on feeling states when cultivation always tells you to get rid of the view of the body, and to detach from sensations! However, in manipulating your physical and inner energetic (chi) body, you are doing exactly the opposite. You are actually playing with the activities of contact and sensation when you should be looking for the prepositional one that knows them.3
The trap isn't that the bliss is fake. The trap is that bliss is a sensation, and the standing instruction everywhere else in the training is to stop treating sensations as you. You've spent months learning not to grab at an itch, and then something arrives that feels like the point of the whole exercise.
There's a direction-of-travel rule that goes with it, and it's the thing most schools get backwards. Emptiness makes the bliss, not the other way round. "If you weren't able to cultivate emptiness then these blisses would never arise."6 So cultivating the good feeling in the hope that emptiness follows is pushing the car to make the engine turn over.
A second book by the same author splits the word in two, and the split is worth having because both states get called by the same name.
When your Qi is first stirred up and starts working through your Qi channels, it does not feel blissful at all, and yet the sensations you will feel of internal energy movement are exactly what some schools refer to as the bliss you are supposed to cultivate. However, the real bliss is after you next harmonize all of your awakened internal energy so that it feels comfortable and balanced.10
So the chaotic phase comes first and is routinely mistaken for the destination. The definition of the second state is deliberately small: "Bliss just means that your body feels more comfortable or pleasant." And the same passage names why sitting alone rarely produces it. "meditation alone rarely makes the body feel blissful," because you have to stir the energy first and smooth it afterwards. Most instruction leaves out the stirring.10
The same teacher runs the same procedure three times, on three escalating experiences, and never changes his tone. The repetition is what makes it worth studying.
First. Naked in a freezing cave, warmth comes up on its own and he passes the night in it. Seven days of inner heat and great bliss, arriving effortlessly. Then the Buddhas of the Five Families appear in the five directions.
This experience is like a man pressing his eyes and seeing two moons in front of him as a result. It is only due to your having captured and controlled the energy-winds of the five elements. It is neither good nor bad. Keep meditating.1
Press your eyeball and a second moon appears in the sky. You genuinely see it. Nothing has happened to the moon. Five Buddhas in five directions gets filed in the same drawer as that.
Second. Three months later the universe starts spinning like a wheel. He's dizzy, throws up repeatedly, faints, and lies unconscious for a long time.
This experience is due to the energy-winds in the left and right channels entering into the central channel. It is neither good nor bad. Just continue with your meditation.1
Which, note, is the step the whole protocol calls indispensable — the energy leaving the side channels for the middle one. He's just had the thing happen, and it presents as violent motion sickness.
Third. The cave full of Avalokiteśvaras, each with a moon disc.
This is due to the increase of bindu… in the Great Bliss chakra at the crown of your head. It is neither good nor bad. Keep meditating.1
Three things come out of this. The diagnoses are different every time and they're specific: element-winds, then side-channels-entering-centre, then substance pooling at the crown. That's not blanket dismissal — it's a man reading three separate physical events off three separate presentations, which is what a working diagnostic vocabulary looks like.
The verdict never changes. The mechanism varies in fine detail and the evaluation stays completely flat. That flatness is doing the teaching. Grade these experiences even slightly and the vocabulary becomes a scoreboard, and the student starts farming for the next vision instead of meditating.
And the student was a scholar who knew the texts cold — "even this great religious scholar… could not understand the most basic and trivial transformations of the path."7 He could recite the doctrine and couldn't read his own body, and it took one sentence from somebody who could.
The gloves come off for the next bit.
This is the major technique of Tantra: you concentrate on visualizations and various feeling states to generate the experience of the four dhyāna, but the states you achieve are not called the four dhyāna. Rather, they're renamed the states of co-emergent (simultaneous) emptiness and bliss!3
And: "No matter what anyone says, no matter what Tantric source tries to deny this, these are nothing else than a separate delineation of the characteristics of the four dhyāna."5
Nobody is calling the states fake. They're being called the four standard meditative absorptions under a house brand — and the house brand exists so the product looks unavailable anywhere else. "This is actually a bit of propaganda put forward by the school to help keep the transmissions alive."6
The endocrine reading is what licenses that. If bliss has a physical cause, the same cause gives the same state whoever produces it and whatever they call it. A school claiming a genuinely unique state would have to point to a unique physiology, and nobody does.
Then, on the very same page, the case for the other side gets made, which is rare enough to quote whole:
In truth, the stage of emptiness is already there but Tantric masters think it's easier to cultivate the body first. Tantra therefore adopts this attractive pathway in order to get you started on the spiritual path that in truth, very few of us really set out to attain. From this standpoint of compassion, can we blame the school at all?6
Both readings sit two paragraphs apart and neither wins. They're not the same story — propaganda to keep the lineage funded and a nice-looking door because nobody walks through a plain one are different accounts of the same decision. From outside they look identical, and they may be identical, differing only in what the teacher thinks he's doing.
The concession that follows is the more interesting criticism, because it's about design rather than motive. Tantra's heavy late emphasis on emptiness is "trying to repair the damage that it may have done, in encouraging a clinging type cultivation on form, by now doubly stressing the factor of emptiness at the end."6 Lead with the body and you spend your advanced teachings prising students off the attachment your beginner teachings built. The attractive on-ramp gets paid for downstream — by everybody, including the people who'd have come in through the plain door.
The heat comes up through the chest and there's something with it you'd honestly call joy. It isn't emotion. It's more like sweetness, physical, spreading. You've been sitting for forty minutes and you'd very much like to know what it means.
It means your glands moved. That's the whole content of it. The same movement comes from breathing hard, from being ill, from a blocked channel finally giving way, from any number of things that happened in your body this morning. So take the verdict off the shelf and use it: neither good nor bad, keep meditating. Three words of diagnosis and three of instruction, with no gap in the middle where interpretation could get in.
Then watch for the polite version of the same mistake, because it's the one you'll actually make. You've stopped chasing the bliss — you're much too sensible for that — but you've started checking for it, and a session without it has begun to feel like a poor session. That's the same error wearing modesty. A signal with several possible causes tells you nothing when it's absent either.
For the sitting itself, keep the arrow pointing the right way. Don't work up the feeling and wait for emptiness to follow; it runs the other direction, and the blisses come out of emptiness rather than into it.6 And when the sweetness does arrive, move attention off the sensation and onto whatever is registering it — "the prepositional one that knows them."3 Not away from the bliss, which would be suppression. Behind it.
Before you credit anything, check the cheap explanations first. How hard were you breathing? How long did you hold anything? Are you coming down with something? Has a spot in your back been aching for three weeks and just stopped? If any of those is live, that's your cause.
And if the practice you're being sold names a state you've never heard of anywhere else, ask what physiology would make it unique. A proprietary name over a generic mechanism is a brand.
Last, keep the requirement and drop the significance. The bliss still has to happen — the later attainments are built on it having happened.5 Needing something and reading your fortune in it are two different acts, and only the second one is the mistake.
[POPULAR SOURCE] throughout. The Tibetan material arrives through Glenn Mullin's Six Yogas translations rather than primary sources, and the Mencius passage via D. C. Lau — cite as Bodri citing the translators.51 [SINGLE SOURCE] on the endocrine identification, which is asserted at p 99 and given its content at p 409, four hundred pages apart, with the book never joining them.24
The tension the source leaves open is a practical one. Bliss is a natural prerequisite for the attainments that follow,5 and bliss is a sensation you're told to detach from.3 The state is required and attending to it is the error, and no procedure is offered for having something you mustn't notice.
⚠ The renaming charge rests on an argument from absence — where did Buddha ever say these separate states existed — and no range is cited to support it.6 By this vault's standard that isn't strong enough to carry the confident register it arrives in.
And the standing limit: these blisses are rungs on a ladder the book's own footnote 518 calls false stages, whose three real jobs it names as rest stops, verifications and motivational assists.8 Bliss is the clearest motivational assist in the book, and the footnote licenses that role and no more.
Open questions. If the same endocrine state is reachable by breath forcing, by illness and by emptiness, does anything distinguish the cultivated version from the inside? And what does a practice for having a state you mustn't attend to actually look like?
Two instructions about the body run through this material, and on any given afternoon they pull opposite ways.
One says build it. Heat at the navel, energy into the central channel, the breath allowed to stop, jing conserved — an entirely physical programme with physical markers, and the tradition calls its foundation the inner heat and means it.
The other says put it down. Stop treating sensations as yourself, quit playing with contact and feeling, look instead for the thing that knows them. Follow that one honestly and you'd never take an interest in your own navel.
They're sequenced rather than contradictory, and the sequence is never spelled out. You work the body until working it becomes the obstacle. What makes it hard from inside is that both instructions are live on the same cushion, and nothing tells you which day you've crossed over.
Against Jaḍa Samādhi and the Biofeedback Problem, this is the harder half of one problem. There, a physical readout gets produced deliberately and mistaken for the state. Here the readout arrives honestly, as a by-product, and still isn't the state — which is worse, because nothing was faked and the practitioner has no reason to suspect a thing.
A real chemical event that says nothing about its own cause — Placebo: When Belief Rewires Neurobiology. That page corrects the popular picture. Placebo isn't a sugar pill tricking somebody into imagining they feel better. Label the pill a painkiller and the brain releases its own opioids — the same molecular cascade morphine sets off, in the same places. The relief is chemically real. It just isn't evidence about the pill.
Cultivation bliss has the same shape, and putting the two side by side settles something neither settles alone. The bliss is a genuine endocrine event, reliably produced, and necessary for what comes after. And its reality is exactly why it can't testify about its own cause, because the same cascade runs from emptiness, from forced breathing, from a channel grinding open, and from expecting it.
Which gives a rule that applies well outside either field: the more reliably a good feeling can be produced, the less it tells you about which of its causes produced it this time. Reliability and diagnosticity trade against each other. A state with one cause and one trigger would be strong evidence. A state you can reach five ways is no evidence at all.
That inverts what practitioners on both sides actually run on. Patients trust the relief because it's undeniably real. Meditators trust the bliss because it's unmistakable. In both cases the very quality being trusted — the vividness, the reliability — is the thing that destroys its value as a signal.
And it explains why the verdict has to be flat rather than graded. Against a signal with many causes, the only honest reading is no reading. Which is precisely what it is neither good nor bad says, three times, to three different mechanisms, in three escalating weeks.
One handshake. A second — that a proprietary name over a generic mechanism is a branding operation — is the argument Method Accepted, Result Rejected already carries, and repeating it here would be restatement.
Sharpest implication. How reliably you can produce a feeling and how much that feeling tells you are inversely related. A bliss dependable enough to arrive on schedule is a bliss too many routes can reach for it to testify about any of them. So the only honest response to a strong, unmistakable, physiologically real spiritual experience is the one Milarepa gives three times to three different men on three different mornings: it is neither good nor bad, keep going.
The second edge is in the protocol rather than the warning. Everything in the Six Yogas sequence hangs off one physical event — the breath stopping by itself — and every transformation is said to come from that state.5 If that's right, the whole elaborate business of heat, syllables and channels is downstream of a single switch, and most of what practitioners spend years working on is scaffolding around a thing that either happens or doesn't. Nobody in this material says how to make it happen. They only say what rests on it.
Generative questions.
