Most traditions that describe ecstatic symptoms describe them and stop. Tears come, the hair stands up, the voice breaks — these are things that happen.
This one supplies a route.
When the mind is overpowered by spiritual emotions in relationship with Śrī Kṛṣṇa, it submits unto the vital air,
prāṇa. The vital air then also experiences transformations, causing the body to become excessively agitated. At that time, thesāttvika-bhāvasmanifest on the body… As the vital air moves throughout the body, it comes in contact with the five elements and thus produces differentsāttvika-bhāvas.1
Mind → prāṇa → element → symptom. Three steps, with a named intermediary, and a table at the end.
Prāṇa in contact with:
Earth → stambha, becoming stunned.
Water → aśru, tears.
Fire → sveda, perspiration, and vaivarṇya, change of colour.
Sky → pralaya, loss of consciousness.
Air → three symptoms, graded by intensity: mild → romāñca, horripilation; moderate → kampa, trembling; intense → svarabheda, faltering of the voice.2
Eight symptoms, five elements. Fire takes two, air takes three by intensity, and the other three elements take one each.
Run the correspondences and most of them are doing honest work.
Earth → stunned. Earth is the element of solidity and immobility. Stambha is defined as loss of voice and suspension of the function of both the working and knowledge-acquiring senses — a person become inert. The mapping is transparent.
Water → tears. The only liquid symptom, the only liquid element. Trivially right.
Sky → loss of consciousness. Ākāśa is the element of space, of emptiness, and pralaya is defined as cessation of the function of the senses and the merging of the mind into the object of love. Emptiness of the faculties to the element of emptiness.
Fire → perspiration and colour change. Heat produces sweat; heat produces flush and pallor. Two symptoms, one thermal mechanism, one element.
Air → three, by force. And this is the cleverest assignment, because air is the only element that comes in degrees of movement. A light current raises the hairs. A stronger one shakes the body. A strong one disturbs the breath, and the voice — which rides on breath — breaks.
That is a single physical variable producing three distinct symptoms in ascending order, and the tradition uses it as such.
The five elements with their ascending qualities are not this tradition's invention; they are standard Indian cosmology, and this book uses the same scheme two Texts later for something entirely different — the accretion model, where ether has sound, air has sound and touch, fire adds form, water adds taste, earth adds smell.
So the elements are load-bearing twice in the same Division, on two unrelated jobs: grading the five rasas, and routing the eight symptoms.
Which is worth noticing, because it is evidence about method rather than about physiology. This tradition reaches for the elemental scheme whenever it needs a five-fold ordering with an internal gradient — and it is a good tool for that, since the elements come pre-ordered and pre-differentiated.
The cost is that a scheme used for two unrelated purposes in one Division cannot be doing explanatory work in both. In the accretion model, the elements' cumulative qualities are the argument. Here it is their material natures. Same five items, two different properties recruited.
The interesting question is not whether the physiology is right. It is why the tradition wanted one.
Consider what the mechanism buys.
It makes the symptoms non-arbitrary. Without a route, an eight-item symptom list is just a list, and there is no reason it could not be nine or six. With a route, the eight are derived — five elements, one of which subdivides by intensity and one of which produces two effects.
It explains why these and not others. Why not laughter, why not fainting-plus-nausea, why not a hundred things a body does? Because these are what prāṇa produces on contact with the five elements, and the elements are exhaustive.
And it locates the symptoms outside the will, which is exactly what the anubhāva/sāttvika-bhāva distinction requires. Dancing is chosen; the prāṇa route is not something a person operates. The mechanism is what makes the involuntary classification more than a stipulation.
So the physiology is doing taxonomic work, and it is doing it well. Whether anything in it is anatomically true is a separate question the tradition does not raise and this page will not settle.
There is a detail in the first step easy to read past: the mind submits unto the vital air.
Not acts on. Not disturbs. Submits — the mind gives way, and the prāṇa takes over.
Which fits the whole architecture. In this system the practitioner does not produce bhāva; bhāva appears when an obstruction clears. Here the mind does not produce the symptoms; it surrenders to something that does.
The same shape, one level down: agency handed off at every stage. Sādhana clears rather than causes; bhāva arrives by mercy; and when it manifests, the mind's role is to stop governing.
[n≥3 PATTERN] on the shape — obstruction-removal in the definitional material, mercy-arrival in Text 12, and mental submission here. Three independent instances of the same move in one book.
You have physical responses in practice — the throat closing, the hair rising — and you want to know what to make of them.
The mechanism gives one genuinely useful thing: these are downstream of an involuntary route, so treating them as achievements or failures is a category error in both directions. The prāṇa is not something you operate.
Second scene, and this is where the page has to be careful. The three air-symptoms are graded by force — mild, moderate, intense — which invites reading your own horripilation as a small reading on a gauge.
Text 16 blocks that, and the block is the one to hold: display is a function of the container. The prāṇa route explains which symptom appears given which element; it says nothing about how much the person was moved. The elemental table is a routing diagram, not a meter.
Third. What the mechanism genuinely licenses is a kind of relief. Devotional traditions produce a great deal of anxiety about whether one's physical responses are real, manufactured or absent. The physiology says the symptoms have a route that runs through a faculty the practitioner does not control — which makes the anxiety, if not misplaced, at least aimed at something outside its own jurisdiction.
Compare two ways of presenting eight symptoms.
As a list. Stunned, sweating, hair standing, voice breaking, trembling, colour changing, tears, collapse. Eight items with nothing joining them. Anyone could add a ninth, and the tradition would have no principled objection.
As a derivation. Five elements; air subdivides by force into three; fire produces two. Eight follows.
The second is not more true. It is more closed — and closure is what a canonical list needs.
And you can watch the closure doing its work elsewhere in this book. The vātsalya-rasa material names a ninth sāttvika-bhāva, unique to that rasa: stana-sravaṇa, milk flowing from the breasts. A ninth symptom is exactly what a derived eight should not permit.
So either the derivation is not exhaustive, or the ninth is a different kind of item. The book does not say, and the two passages do not meet.
Which is the honest reading of what the physiology accomplishes: it makes the eight look necessary, and the tradition then quietly exceeds them when a rasa requires it.
Stated at the strength the evidence carries: one derivation, one exception, in one book. [n=1 OBSERVED].
Strongest support. The mind-to-prāṇa-to-element route is stated in continuous prose in Text 14, and the correspondences are given as an explicit table with air's three grades named.
Tension one. The vault's enrichment material records a ninth sāttvika-bhāva unique to vātsalya-rasa — milk flowing from the breasts. A five-element derivation yielding exactly eight has no room for a ninth, and the two passages are in different Texts.
Tension two. The elemental scheme does two unrelated jobs in one Division: routing symptoms by material nature here, and grading rasas by cumulative quality in the accretion model. Same five items, two different properties recruited, no cross-reference.
Tension three. Fire produces both perspiration and colour change, and air produces three symptoms. So the mapping is not one-to-one in either direction, which weakens the derivation's claim to explain why there are exactly eight.
Open question. Is the prāṇa here the same prāṇa as in the yogic literature — one of five vital airs with a specified seat and function — or a general vital principle? The passage says vital air without further specification, and the difference matters for whether this is a borrowed technical physiology or a devotional use of a familiar word. Nothing in the range read settles it.
The vault's Bryant material presents the sāttvika-bhāvas as involuntary physical symptoms the tradition reads as devotional evidence — accurate, and stopping at the classification.
The mechanism is what this book adds, and it changes the classification's standing. An involuntary symptom with no stated route is a claim; one with a route is a claim plus an account of why it could not be otherwise.
And it converges with the pattern the ingest keeps finding, which by now has enough instances to state as a regularity: wherever Bryant reports a category, this book supplies the machinery underneath it — the definition's failure conditions, the practice's stimulus catalogue, the symptom's causal route. The categories are shared; the machinery is where this source's contribution lives.
A route between emotional state and bodily symptom, with a named intermediary. Set this against The Somatic-Psychological Circuit: Why Body and Mind Cannot Be Separated in Healing, whose finding is that the split is false at the level of the nervous system — that the circuit is bidirectional, that state changes body and body changes state, and that any account treating one as upstream of the other will fail in practice.
The prāṇa route is a pre-modern statement of the same refusal to separate, with one instructive difference: it is strictly unidirectional. Mind submits to prāṇa, prāṇa contacts elements, elements produce symptoms. Nothing flows back.
What the pair produces that neither yields alone. The unidirectionality is not an oversight; it is required by the taxonomy. If the circuit ran both ways, then producing the symptom could produce the state — and the entire anubhāva/sāttvika-bhāva distinction, the seven-rung forgery scale and the niḥsattva category (symptoms by forced practice) exist precisely to deny that.
Which means the tradition has a strong doctrinal interest in a one-way circuit, and the somatic literature has strong evidence for a two-way one. And the tradition's own niḥsattva category concedes the return path exists — the picchila heart produces the symptoms by practice — while classifying its products as counterfeit.
So the disagreement is narrower than it looks and sharper for it: both agree the body can be driven from the outside. They disagree about whether what arrives that way is the same thing. The somatic account says the state is real because the circuit is real; the devotional account says the circuit is real and the state is still counterfeit, because provenance is what it grades. That is a genuine fork, and it is the clearest case in this vault of two systems agreeing on a mechanism and dividing on what the mechanism produces.
One handshake here rather than two. The derivation-makes-a-list-look-necessary finding is a point about taxonomy closure, already carried in the Analytical Case Study at higher resolution than a second connection would add.
Sharpest implication. The physiology's unidirectionality is doctrinally load-bearing rather than merely descriptive — a two-way circuit would let the symptom produce the state, which is exactly what the tradition's forgery apparatus exists to deny. And the same book concedes the return path works and calls its products niḥsattva.
Generative questions.
vātsalya has a ninth. Is the derivation exhaustive or illustrative?
