Of every claim in six hundred pages, exactly one can be checked by a stranger: "During the appearance of the state of ching-an, it's common for the pituitary gland to secrete a sweet tasting hormone that appears in your saliva, and which you should readily swallow. This sweet secretion is not an imaginary phenomenon because it can be objectively tasted by any third party who kisses you."1
Read that against everything around it. The visions are private. The blisses are private. Emptiness, clarity, the collapse of the discriminating mind, the four voids of sleep — all of them are reports from inside a head, assessed by the person whose head it is.
This one leaves a residue in the mouth. It's present, physical, and tasteable by someone with no stake in the outcome and no training at all. And the instruction attached to it is two words: swallow it.
The state it belongs to is ching-an — physical coolness, mental lightness, emptiness, and this sweet saliva. It's the run-up to samādhi, and it lines up with jing turning into chi and the front and back channels opening.2 3 In the Indian and Tibetan schemes that's the iḍā and piṅgalā channels opening, and in the Jewish tradition it's read as the two pillars, Boaz and Jachin, in Solomon's temple.2
The taste is graded, and the grading is oddly specific. Both the sweetness and the thickness shift with which of the five tattwas is dominant — the Hindu word for the five elements. Earth dominant makes it very sweet. A bit too much fire turns the sweetness slightly bitter. Too much air makes it slightly acidic.2 The Chinese schools explain it differently because they use a different medical system, but the point survives the translation: flavour and consistency change with your condition.2
Then a piece of first-person testimony, worth separating from the doctrine because it contains something the doctrine doesn't: "I have experienced the sweet dew many times myself so as to be able to verify its actual existence, and from my own experience I can say that it will appear when you cultivate intensely, but if you stop your cultivation for several days then it will also disappear as well."2 Appears with practice, goes away without it, over days. That's a reversible sign that tracks a dose, which is a much stronger kind of claim than anything else described here.
And the cheap explanations get closed off before anyone offers them. A very minor look-alike can turn up in people with fairly clean channels doing long athletic work — running, specifically — but it lacks "the factors of true sweetness or abundancy."3 It also sometimes appears in the right sort of partnered sexual cultivation, again only if the channels have been cleaned to some degree.3 And the obvious modern guess is refused outright: "don't jump to the conclusion that this substance is an endorphin, because it's not. It is a sweet tasting endocrine secretion, of a very unique nature, which only manifests as a result of the purificatory processes of cultivation."3
The taste is a sign of something, and the something has a consequence that's easy to read straight past. The feelings at ching-an are hard to put into words — the Chinese phrase quoted is that one is "internally touched by wonderful pleasures." And then the line that matters: "A person can detach himself from worldly desires only by progressing to this point."6
Only by progressing to this point. Not more easily. Detachment is unavailable before the threshold and available after it.
That flips the order most people assume. The usual picture is that renunciation is the discipline and the state is the reward — you give things up, and eventually you stop wanting them. Here the state comes first, and the giving-up becomes possible because of it. Which means every earlier attempt at detachment is willpower pushing against an appetite that's still fully switched on.
Three things follow, and they reach a long way past this passage. It explains why the beginning is the worst part. Not because a beginner has less resolve, but because a beginner is doing by force the one thing the practice will later do for them.
It changes what the hundred days of retention is buying. It isn't a test of character. It's the price of reaching a state after which the same restraint stops costing anything.
And it makes the sweet taste practically useful rather than merely interesting. A marker for ching-an is a marker for when to expect the fight to stop, which is a more useful thing to carry than another sign of progress.
The list of names is the longest single-item convergence in the book: "This sweet salivary hormone is actually the famous 'soma' of the Hindu Vedas, 'ambrosia' of the Greeks, 'madya' (divine wine) of the Tantras, 'sweet wine' of the Sufis, and 'amrita' nectar of the Gods. It is also the 'grail wine' of the Medieval Christian mystics and the 'fountain of youth' of European legends."2
The Haṭha Yoga Pradīpikā says the yogi who drinks the pure stream of nectar is freed from disease, has longevity, and has a body as soft and beautiful as a lotus stem — and elsewhere that it's like milk, ghee or honey, and wards off fatal disease, old age and weapons.1 The Taoist Tsan-tung-chi describes what it does in the body, and the sequence is worth having in the order it's given: the nectar moistened their skin and flesh, their tendons and bones went soft and strong, they expelled the internal toxins, they held on to their true energy, and after a long accumulation of all that their bodies were transformed.7
The Wu-jen p'ien puts it as a reproach: "Everyone originally has the medicine of immortality within. However, they have lost their understanding and thrown it away. When the sweet dew descends, sky and earth will be joined."7 And then two lines about who won't believe it — "A frog in a well will say there is no dragon's cave. How can a quail know about a phoenix's nest?"7 — before the practical point: when the elixir is mature, gold naturally fills the room, so why go looking for herbs or praying to heaven for a longer life.7
Then the sentence that makes the whole list argue in an unexpected direction: "You can find it mentioned everywhere not because it's been a popular symbol to pass along from school to school, but because it's such a low stage of achievement. Being such a low stage of achievement, most all genuine spiritual schools have practitioners who achieve it, and it's a stage of attainment which is unmistakable when it manifests."2
Turning up everywhere is evidence of being early, not of being central. It's the thing everybody hits because everybody gets that far, and most people get no further. Which also disposes of the borrowing objection without needing a history: if the sign is common because it's easy, no transmission story is needed to explain why eight traditions have a word for it.
Alexandrine Gnosticism is about as far from a Taoist alchemy manual as a school can get, and a single line of it gets read here as a step-by-step description of this process, with the decode printed inside it in brackets. The perfect man descends into the Virgin's womb — read as the tan-tien, the field in the lower abdomen. He removes the impurity contaminating the firstborn of water — read as purifying the jing, the dense sexual essence. He washes himself — read as the chi starting to circulate through the whole body. And he drinks from the living waters — read as the secretion coming down.3
Four clauses, four stages, in order: site, purification, circulation, descent. That's the same order as everything else on this page. The jing has to be cleaned before it turns into chi, the chi has to be moving before the channels open, and the nectar arrives at the end rather than anywhere earlier. The Taoist master Huan Yuan-chi gives the same thing as a two-line rule about temperature: "In terms of cultivation, when fire warms water, pure yang arises. When water cools fire, 'sweet dew' appears."3 Heat under water raises something. Water over heat condenses something. And the condensing is what lands in your mouth.
Two things are worth being straight about. The brackets are not in the Gnostic text — they're the decode, inserted into the quotation.3 And the same treatment is applied to Judges 15:19, where God opens a hollow place in the jaw and water comes out and Samson revives, which the original describes as a spring rather than as anything happening inside a man.1 That reading is recorded here and not built on.
What the case study is actually good for is the sequence. Strip the vocabulary off four traditions and the same four steps keep coming back in the same order, and the order is the theory: you don't get the last one without the first three.
The nectar sits inside a scheme of medicine that places it exactly. Wai-dan, external medicine, splits three ways. Earthly medicines are the plants and minerals you swallow. Heavenly medicines are the divine responses you get when you pray for help. Human medicine is partnered sexual cultivation that can help heal the body or help the practice.2
Nei-dan, internal medicine, is your own jing, chi and shen — and it outranks all three: "your own jing, chi and shen are the top of all forms of medicine in existence."2 The sweet secretion is filed under nei-dan, and the filing comes with a deflation: "it, too, is just a sample of your own internal medicine."2 Just a sample. The most impressive checkable phenomenon in the book is offered as a specimen of a category rather than as its summit.
One more technique gets named in the same breath and then dropped. From the Can Tong Qi: "you can use the light of your own mind to internally look at your body inside. By focusing upon any diseased part and viewing it, in this way you can use your own shen to cure yourself."2 Named, not developed — which is the standing pattern in this material, sitting right beside the one thing that does get developed all the way.
The most concrete piece of writing anywhere in the book is a footnote, and it's laid out like a research proposal. It opens with a reading list picked to span four traditions and establish that the phenomenon is independently attested: Nan Huai-Chin's Tao and Longevity, Satyananda Saraswati's tantric course, Lu K'uan Yu's Taoist Yoga, Rieker's The Yoga of Light, Muktananda's Kundalini.4
Then a candidate mechanism with reasoning attached. The amylase enzyme sits in great quantity in the genital tissues, which are where jing is held. Since ching-an is the point where jing becomes chi, "it would be natural to assume that this sweet pituitary hormone would somehow affect the jing, and thus the receptors for it would be greatly concentrated in the sexual organs and kidneys."4
Then an alternative, offered with an observation against it already attached: "perhaps it is a tryptamine compound although it produces no psychological effects."4 Then the thing to be tested, stated as a claim rather than as a fact: "there exists a substance in saliva (produced under these rare conditions) that appears to be an anti-aging, anti-sickness, anti-anxiety factor. If you can identify it, it can be made into a pharmaceutical."4
And then an admitted uncertainty with an anatomical argument for the underdog: "It's unclear whether this hormone issues from the pituitary gland or pineal gland. While many assume it's from the pituitary gland, it might be helpful to note that the pineal gland is originally formed not out of brain tissue, but out of specialized cells originating in the roof of the fetal mouth."4
Note the direction that last point pulls. The gland the mouth's own tissue helped build is the one nobody defaults to.
The promotional claim wrapped around all of it runs harder than the proposal does. Modern medicine promotes DHEA, melanin, human growth hormone, oestrogen and progesterone for anti-ageing, and against that: "this substance should absolutely, without doubt, be the major focus of anti-aging hormone research," on the grounds that absorption attainments are the only route to a long life worth having, and this is the hormone that starts the physical changes which make them possible.2
You're practising and your mouth tastes sweet. On this account that's a stage marker — ching-an, the run-up to samādhi, jing turning into chi — and there's nothing to do with it except swallow.1 No technique, no visualisation, nothing to hold or direct.
Then the check that separates this from every other sign in the book, and it's free. Ask someone. A sweetness another person can taste is a sweetness that exists; one only you can taste may be attention. The test is named on the page and it costs nothing to run.
Then the slow version, which you can run alone. Practise intensely and it should appear. Stop for several days and it should go.2 If yours doesn't track practice like that, whatever it is, it isn't what's being described here — and that tracking is the whole content of the claim.
Watch the flavour too, because it's supposed to move. Very sweet, slightly bitter, slightly acidic — the three named variants, tied to which element is running high.2 A taste that never changes is a different observation from a taste that shifts across months.
And the thing to expect from it, which is the reason the marker is worth having. If detachment only becomes available at this threshold,6 then everything you're doing before it is willpower against a live appetite, and it's supposed to be hard. That's not a sign the practice isn't working. It's a description of where you are on the road, and the marker is how you find out that the road has changed under you.
Strongest support. The third-party test.1 A secretion someone else can taste is categorically different evidence from a reported inner state, and it's volunteered rather than extracted. With the dose-response and the excluded endorphin explanation beside it,2 3 this is the only claim in the book built to be checked.
The central tension. The pituitary is named confidently in the body text and openly doubted in the footnote, which raises the pineal on anatomical grounds.1 4 The confident version is what travels; the honest one is below the line.
A second tension, in the promotional claim. This substance should absolutely, without doubt, be the major focus of anti-aging hormone research2 is stated with a certainty that its evidence — one person's testimony plus cross-tradition attestation of a taste — cannot carry. The proposal is careful. The sentence wrapped around it isn't.
A third, on the ubiquity argument. If a phenomenon reported everywhere is early rather than deep,2 then the cross-tradition list that opens the section is evidence for the deflation and not for the importance — and both readings are offered on the same page, four paragraphs apart.
Source notes. ⚠ The eight-name identification list is given with no source for any of the identifications.2 Three Haṭha Yoga Pradīpikā citations come through the Bihar School edition, two Taoist texts through Eva Wong's Teachings of the Tao, and the Huan Yuan-chi line through Red Pine.1 7 3 ⚠ The Alexandrine Gnostic passage and the Samson passage both carry bracketed decodings inserted into the quotation, and the Judges reading in particular is the concordism pattern this build excludes — recorded, not built on.1 3 🚩 SECONDARY WITHOUT PRIMARY throughout.

And the standing scope limit. Ching-an is the run-up to samādhi — an early rung on a ladder footnote 518 calls false stages, whose three real jobs it names as rest stops, verifications and motivational assists.5 The same verdict is given here in plainer words: such a low stage of achievement.2
Absence note. Drawn from pp 344–346 and footnote 301. Nothing here claims what the source says outside that range.
Open questions. Everything needed to test this has been in print since 2002 — a population, a marker, a control condition, a third-party assay and two candidate compound classes — and nothing suggests anyone has run it. And: if turning up everywhere means a thing is early, what should be made of the phenomena only one or two traditions report? Are those the deep ones, or just the local ones?
Two accounts of what the nectar is sit on the same three pages, and they pull in opposite directions. On the first it's the summit of the pharmacopoeia. The premier substance a biochemist should be isolating, the real youth-producing soma, the thing that should absolutely and without doubt be the major focus of anti-ageing research, more directly related to curing illness and ageing than the piecemeal battles fought over one hormone at a time.1 2 Follow that and the nectar is a destination, and the practice is what produces it.
On the second it's a specimen. Just a sample of your own internal medicine, at such a low stage of achievement that every genuine school has practitioners who reach it.2 Follow that and the nectar is a road sign. You note it, you swallow it, you keep walking, and treating it as the point is the error.
Both are argued in the same voice within two pages, and the practical difference is whether a practitioner who tastes it should be pleased or unmoved. Read with The Channels Are Nervous Systems, this page supplies the substance that page's identification names. There the spiritual saliva is glossed as endocrine function; here it's a specific secretion with a taste, a dose-response and a proposed assay.
With Bliss Is Endocrine the reading is identical and applied one step over — there to a feeling, here to something you can spit into a cup. And against Experiences Vary by Sex, Age and Health, the contrast is instructive. There, two near-exhaustive catalogues are laid over each other and the overlap is offered as evidence. Here the converging item is a single narrow physically specified sign, which is what a convergence has to look like before it carries weight.
Self-Control and Commitment Devices — Binding Your Future Self starts with somebody trying to eat better. They go to the shop meaning to buy well and come home with cookies, and at nine in the evening the willpower goes. Then they change something that isn't willpower at all: they order the groceries online. Now there's nothing in the cupboard, and they eat well without any effort whatsoever. That page's line is exact — they haven't increased their self-control, they've removed their freedom to choose badly.
The nectar page describes a third thing, and putting the two side by side is what makes it visible. The commitment device takes the option out of the room. What's claimed at ching-an is that the appetite goes out of the person: detachment from worldly desires becomes possible only at that point, and before it, it doesn't.6
So there are three different states hiding under the one word restraint. There's willpower, where the cookies are in the cupboard and you're awake at nine fighting. There's the commitment device, where the cupboard is empty and there's nothing to fight. And there's the threshold state, where the cupboard is full and you walk past it because there's nobody in you who wants it.
What the pairing produces is the practical instruction neither page gives on its own. If detachment genuinely isn't available until a threshold you might be years away from, then willpower is being asked to do a job it can't do, for as long as the run-up takes — and the retention regime the whole thing depends on is exactly the kind of long grind that willpower fails at. Which makes the commitment device the correct tool for the pre-threshold stretch, not a lesser substitute for discipline. Empty the cupboard for the hundred days, because the appetite is still fully operational and the tradition itself says so.
And it names what the marker is for. A sweetness in the mouth that comes and goes with practice is, on this account, the earliest available signal that the arrangement can change — that you're moving from a period where the environment has to do the work into one where it doesn't.
One handshake. A second candidate — that the best-built claim in a mixed body of work gets quarantined by the material printed next to it — is about the packaging rather than about the nectar, and belongs in Evidence.
Sharpest implication. Detachment is described as a capacity that switches on at a physiological threshold rather than a virtue you accumulate — which means the long unpleasant stretch before it isn't a test anybody is failing, and the sweet taste is the first cheap signal that the terms have changed. It also means the tradition's own account undercuts the advice it usually gives, because everything it asks of a pre-threshold practitioner is willpower against an appetite it says willpower cannot reach.
Generative questions.
