From the Hermetic to the Neurological — Correspondences
Threshold page between the second axis of the Paret Method (presence, alchemy, hermetism) and the third axis (CNV, polyvagal theory, internal neurology). It reads in both directions: those coming from the hermetic discover that alchemical operations correspond to measurable neurophysiological transitions; those coming from the neurological discover that initiatory traditions have described, in operational and symbolic language, the same processes that today's science of the autonomic nervous system describes in terms of vagal circuits and neuroception.
The Principle
The Paret Method starts from the position set out in One Person, Many Readings: disciplines do not describe different people; they describe the same person from different angles. The human being is always the same. When a seventeenth-century initiatory tradition and a twenty-first-century neuroscience both describe — with incommunicable vocabularies — the same state transition in the same human being, it is not a matter of poetic analogy: it is the same thing seen from two sides.
This page lists the main correspondences between the language of operative alchemy and European hermetism on the one hand, and the language of polyvagal theory, mirror neurons and internal neurology on the other. The correspondences are not speculations: they are the junctions that the clinical, training and documentary research work of Marco Paret and ISI-CNV has recognized and stabilized over three decades.
Why the Translation Works
Operative alchemy — distinct from external metallurgical alchemy — was for four centuries a precise technology for transforming the human being: a sequence of inner operations capable of moving a person from one habitual configuration to another. Operative alchemists did not have fMRI or high-resolution electrocardiograms, but they were extremely fine observers of the body, breath, voice, and state. When they described an operation — dissolution, separation, fixation, sublimation — they described a transition that the subject performed within their own system, a transition that was the object of systematic training in initiatory contexts.
Stephen Porges's Polyvagal Theory, the work on Mirror Neurons by Rizzolatti, the mapping of the Default mode network by Raichle, and the body psychologies of Reich, Gerda Boyesen and Mindell describe — with measurable tools and a non-symbolic vocabulary — exactly the same order of transitions. The two descriptions cannot but correspond, if both accurately describe the same person.
Three Vocabularies for the Same Experience
Many practitioners approaching the Paret Method come from paths of yoga, tantra, Buddhist meditation, or Taoist and Tibetan practices. This page is written with that reader in mind: for each correspondence between hermetic alchemy and neurology, the corresponding Indian or Far Eastern term is also indicated. This is not about superimposing traditions — each has its own genius and history — but about making visible that the same internal operative architecture of the human being is described by all. The Eastern vocabulary offers the richest symbolic-energetic map and the oldest and most refined technical procedures; the European hermetic-alchemical vocabulary adds a different technical articulation, often more condensed, and an operational nomenclature that the Paret Method integrates directly into its own practices; the contemporary neuroscientific vocabulary adds measurability, distinct anatomy, and precise identification of mechanisms. The three readings are complementary and enrich each other.
Fundamental Correspondences
Three Principles, Three Guṇas, Three Polyvagal Circuits
The ternary structure of the internal quality of the human being is one of the strongest points of convergence between different traditions and contemporary research. Three different vocabularies — one hermetic-Paracelsian, one Indian, one neuroscientific — describe the same architecture.
- Hermetic-Paracelsian vocabulary
- The Tria Prima describes the human being (and every natural thing) as a combination of three qualitative principles: Sulfur (☉) — the expansive, flammable, active principle; Mercury (☿) — the mediating, mobile, communicative principle; Salt (♁) — the stabilizing, containing, fixed principle.
- Indian vocabulary
- The Sāṃkhya and yoga tradition describes experience as a modulation of the three guṇas: rajas — the principle of activation, movement, passion; sattva — the principle of clarity, luminous balance, mediating intelligence; tamas — the principle of dense stability, containing inertia, grounding. The parallel with the Paracelsian triad is precise: Sulfur ↔ rajas, Mercury ↔ sattva, Salt ↔ tamas.
- Neuroscientific vocabulary
- Stephen Porges's Polyvagal Theory describes the autonomic nervous system as the hierarchical modulation of three circuits: sympathetic circuit — mobilization, action-oriented activation; ventral vagal (myelinated) circuit — social engagement, communication, state-switching flexibility; dorsal vagal (unmyelinated) circuit — containment, tonic immobilization, stability.
The correspondence is precise across all three vocabularies: Sulfur ↔ rajas ↔ sympathetic, Mercury ↔ sattva ↔ ventral vagal, Salt ↔ tamas ↔ dorsal vagal.
The added value of the Western vocabularies (hermetic and scientific) over the Indian one is not one of truth — the three systems describe the same reality — but of operational precision. The guṇa system, though very ancient and profound, operates by modulating diffuse qualities: all guṇas are always present simultaneously in any state, and it is a matter of sensing their proportion. The Paracelsian tradition and European hermetism distinguish more sharply between prevailing principle and subsidiary principle, and formally generate the six binary configurations that become the Sei tipi caratteriali del Paret Method. The polyvagal theory pushes clarity further: the three circuits are anatomically distinct (different nerve branches, myelinated or unmyelinated, with different phylogenetic origins), functionally measurable (HRV, vagal tone, skin conductance), and their transitions are governed by a precise mechanism, neuroception.
For the many practitioners of yoga, tantra, and Eastern meditative arts who frequent the Method, this is an entry point: the same three principles known under the names rajas, sattva, and tamas are found in the European hermetic tradition under the names Sulfur, Mercury, and Salt, and in contemporary science in the anatomical and functional form of the three polyvagal circuits — with a progressively greater level of technical articulation that allows focusing on the essential points of practice.
The six binary combinations of the ternary structure generate the six configurations of the Sei tipi caratteriali del Paret Method, readable as six stable polyvagal states. The key entry is I sei tipi caratteriali nella mappa polivagale; the precise comparison between guṇas and Tria Prima is developed in Guna e Tria Prima.

Alchemical Presence and Ventral Vagal Tone
The Integral Presence™ of the Method, the presence of European initiatory traditions, the custody of the heart of Eastern hesychasm, the sub specie interioritatis of the alchemists — all designate the same quality of state: a calm vigilance, a steady perceptual openness, a non-defensive readiness for engagement.
In neurophysiological terms, this quality of state corresponds to the stable activation of the ventral vagal circuit in the absence of defensive sympathetic or dorsal activation. Measurable correlates include high heart rate variability (HRV), broad diaphragmatic respiratory tone, fine modulation of voice and facial expression, and preferential activation of the social engagement system.

Solve et Coagula and the Autonomic Dissolution-Re-coagulation Cycle
Solve et coagula — dissolve and re-coagulate — is the dynamic engine of the alchemical work: the sequence in which a stable configuration is dissolved so that it can be recomposed into a new arrangement. In the practice of strong somnambulism of the Method, solve et coagula is the operational name for the deep trance induction technique.
In polyvagal terms, it is the cycle: dissolution = suspension of voluntary cortical control and habitual patterns of autonomic state; the subject passes through a zone of plasticity where the ventral vagal remains active (preserving contact and consciousness) while the sympathetic and dorsal reconfigure; re-coagulation = stabilization of the new autonomic state. The mesmeric crisis documented in Emotional Release and the autonomous movement of the crisis are clinical manifestations of this cycle.
Four Stages of the Work and Phases of Neurophysiological Transformation
The four stages of the work — nigredo (blackening, dissolution), albedo (purification, washing), citrinitas (illumination, yellowing), rubedo (reintegration, reddening) — describe a sequence of state that has a neurophysiological counterpart.
Nigredo corresponds to the dismantling of habitual patterns, the suspension of the Default mode network of self-narration, and the passage through a non-defensive dorsovagal zone. Albedo corresponds to the cleansing of perception, increased interoception, and the opening of the sensory field. Citrinitas corresponds to cognitive illumination, interhemispheric integration, and effortless clarity. Rubedo corresponds to stable re-coagulation into an integrated ventral vagal state — the reintegrated person, present, capable of effective action.
Abdominal Center: VITRIOL, Hara, Dantian, and the Enteric System
The lower abdominal center as the primary operative seat is one of the most precise points of agreement between independent traditions. European hermetic alchemy makes it the condensed formula of the work: VITRIOL — Visita Interiora Terrae Rectificando Invenies Occultum Lapidem, "visit the interior of the earth and by rectifying you will find the hidden stone". The terrae interiora is one's own belly, and the "stone" is the anchored state. The Japanese tradition calls this place hara — seat of ki and center of gravity of the person. The Taoist tradition calls it the lower dantian — the first of the three cinnabar fields — and makes it the foundation of all neidan (internal alchemy) practice. Yoga recognizes it in the manipura chakra and in the practices of uddiyana bandha. These are all names for the same operative region.
Contemporary neuroscientific research has shown why all these traditions converge on the same point: the lower abdominal region is the seat of the enteric nervous system, a network of about five hundred million neurons lining the gastrointestinal tract, which recent literature calls the "second brain" (Gershon, 1998). It is also the seat of the densest afferent nuclei of the vagus nerve: about eighty percent of vagal fibers are afferent — they carry information from the gut to the brain, not vice versa. Working consciously on the abdomen therefore means modulating the main flow of viscero-cerebral information, and through it, the overall autonomic tone.
The deep diaphragmatic breathing that traditions call hara breathing, dantian breathing, alchemical breathing or bhramari — albeit with different specific techniques — produces the same neurophysiological effect: activation of vagal parasympathetic tone, increased heart rate variability, stabilization of the hypothalamic-pituitary-adrenal axis. The "stone" that the alchemical tradition describes as the object of the work functionally coincides with the autonomic stability that contemporary psychophysiology can measure.
For practitioners of Eastern traditions, this is one of the points where the European hermetic tradition — apparently more abstract — turns out to be the most technical: the VITRIOL formula already contains, in condensed operational form, the precise indication of where to look ("interiora terrae"), what to do ("rectificando", correcting), and what to find ("occultum lapidem"). The Taoist dantians and the Japanese hara locate the point; the hermetic tradition articulates the sequence of the operation; neurophysiology measures the effect.

Magnetic Gaze and Mirror Neurons
The magnetic gaze described by Marco Paret as a continuation of the European Donatist and magnetic tradition — the hippos of the eye, the power of the gaze in world tradition — operates through the mirror neuron system.
The gaze of the fascinator in Presenza Integrale does not communicate a state: it transmits it, because the subject's mirror system motorically simulates the observed state before reflective consciousness intervenes. The transmission of the magnetic gaze is therefore a particular case of polyvagal entrainment mediated by mirror neurons and neuroception: the subject tunes their own autonomic system to that of the fascinator. The key entry is Sguardo e Neuroni Specchio — La Scienza Moderna della Trasmissione dello Stato.
The Petrifying Gaze and Dorsovagal Freeze
The mythological traditions of the immobilizing gaze — the Gorgon Medusa, the basilisk, the jettatore — describe a real phenomenon. Under an intensely predatory or threatening gaze, the subject's nervous system can activate the defensive dorsal vagal circuit response: immobilization (freeze), reduced muscle tone, loss of motor initiative. It is the opposite and symmetrical mechanism of the ventral entrainment of the fascinator in presence.
The myth/neurophysiology bridge entry is La Gorgone e Medusa — Lo Sguardo Pietrificante e il Freeze Dorsovagale nel Mito.
Inner Heat, Kundalini, Secret Fire: Alchemical Thermogenesis
The inner heat that the practitioner can consciously evoke is one of the phenomena that initiatory traditions describe with the greatest consistency. Tibetan Tummo — literally "inner fire" — is the pillar of the Six Yogas of Nāropa and the tsa lung practices. The Indian tantric tradition calls this heat kundalini — the fire-energy depicted as a coiled serpent at the base of the spine that, when awakened, rises along the cranio-caudal axis through the chakras. The European alchemical tradition has its own name for the same operative reality: Ignis Secretus, the "secret fire" of the alchemists, also called philosophical fire — the non-ordinary heat that activates the work and is the precise object of training.
Scientific research has documented the physiological reality of the phenomenon. The landmark study is by Benson and colleagues at Harvard Medical School (1982), who measured skin temperature increases of up to eight degrees Celsius in advanced Tibetan tummo monks — a phenomenon impossible through ordinary thermoregulation — in cold environments and without shivering. Subsequent studies by Kozhevnikov et al. (2013) replicated the result with extended neurophysiological monitoring. The mechanism is now well characterized: it involves non-shivering thermogenesis modulated through activation of brown adipose tissue (BAT), the sympathetic-adrenal system (norepinephrine release), voluntary respiratory control over the autonomic axis, and proprioceptive-imaginative processes that activate specific neural pathways for thermal regulation.
The three traditions describe the same phenomenon with different and complementary emphases. The Indian tradition provides the richest symbolic-energetic map — the image of the serpent rising, the chakras opening, the inner sun rising. The Tibetan tradition has the most detailed and replicable technical procedure, developed in a monastic framework for over a thousand years. The European alchemical tradition, in continuity with the Mediterranean hermetic tradition, gives its precise placement within the arc of the work: the secret fire is what allows the passage from nigredo to rubedo, the operational tool of internal transformation. Contemporary science verifies the phenomenon and articulates its neurophysiological mechanism.
For the practitioner of yoga or Tibetan practices approaching the Method, the relevant aspect is twofold. On the one hand, the Eastern practices they know have a Western counterpart of equal depth — the Ignis Secretus of the European alchemists operates on the same ground, albeit with a less familiar lexicon for the contemporary reader. On the other hand, the neurophysiological reading allows precise distinction of the components of the phenomenon (breath, sympathetic system, brown adipose tissue, active imagination, proprioception) that traditional practice tends to integrate into a single gesture — and this distinction facilitates both training and verification of results.
The historical-comparative integration between Eastern and Western internal alchemy is the subject of The Alchemical Body by David Gordon White (1996), the standard academic reference for the convergence between Indian rasa-yoga, hatha yoga, and the alchemical tradition.

Inner Silence, Emptiness, Śūnyatā, and DMN Suspension
Cognitive quiet — the suspension of the constant inner voice, rumination, and self-narration — is described in all contemplative traditions. The hesychastic tradition and the Desert Fathers call it hesychia, guarded inner silence. The Buddhist tradition calls it śūnyatā, emptiness, and the Vedantic tradition recognizes it in nirvikalpa samādhi. The European alchemical tradition calls it philosophical void or silentium mysticum and makes it the prerequisite of the work.
Neuroimaging studies on experienced meditators (Brewer et al., 2011) and on subjects under psychedelic substances (Carhart-Harris et al., 2014) show in all these states a specific coordinated deactivation of the Default mode network — the brain network that, in ordinary mode, supports autobiographical narrative and mental rumination. The convergence is transcultural: Tibetan meditators, Christian contemplative monks, and subjects under psilocybin show the same neuro-functional signature in the same phenomenological state.
For those coming from an Eastern practice, the contribution of the Western reading is one of precision: the same emptiness experienced in practice can be read as a specific, measurable brain configuration, and this allows distinguishing superficially similar but neurofunctionally different states (absorption, dispersion, dissociation, true samādhi).

Logismoi and Defensive Character Patterns
The logismoi of Eastern hesychasm — the passion-thoughts, the intrusive suggestions systematized by the Desert Fathers — are the compulsive thought patterns that hinder presence. Wilhelm Reich's character analysis describes the same defenses in psychoanalytic-bodily language; Porges's polyvagal reading of trauma reads them as stable patterns of defensive autonomic state (chronic sympathetic, frozen dorsovagal, mixed sympathetic-dorsal active freeze).
The Eight character fixations of the Method are the operational synthesis of this convergence of the hesychastic tradition / Reich / Porges. Entry: Logismoi.
