veins
Within the depth-psychology corpus, 'vein' operates across several distinct registers that rarely intersect but collectively illuminate how Western and Eastern thought models the body as a conduit for non-material forces. In Platonic cosmology — most elaborately in the Timaeus — veins figure as hydraulic channels through which nourishment, blood, and quasi-spiritual substance are distributed in an irrigation system that prefigures later alchemical and psychological images of interior circulation. Plato's explicit ignorance of cardiac muscle function means the vein, not the heart, bears primary responsibility for systemic movement, rendering it a passive conduit whose significance is organizational rather than vital. This hydraulic metaphor persists in Hillman's reading of Harvey, where the clinical demonstration distinguishing veins from arteries marks the moment the heart ceases to be a seat of feeling and becomes a pump. A second, entirely distinct register appears in Kashmirian Tantra as mediated by Jaideva Singh's commentary on the Vijñāna Bhairava: here the 'central vein' (suṣumnā) is the axis of contemplative ascent, the pathway along which breath ceases, kuṇḍalinī rises, and consciousness merges with Bhairava. A third, literalist register appears in psychopharmacological literature — Strassman and Maté — where the forearm vein receives intravenous substances, bridging biochemistry and consciousness research. The term thus spans cosmological plumbing, mystical anatomy, and clinical pharmacology.
Plato, like his contemporaries, drew no distinction between arteries and veins; nor had he any conception that muscular action of the heart had anything to do with the movement of the blood.
This passage establishes that in Platonic anatomy the vein is the sole channel of bodily distribution, its function being hydraulic rather than cardiac, a foundational misapprehension with lasting cosmological consequences.

they cut as covered conduits, under the juncture of skin and flesh, two veins along the back corresponding to the twofold form of the body, with a right side and a left.
Plato's cosmological physiology treats the two principal dorsal veins as architecturally designed irrigation channels, encoding a bilateral symmetry that carries nourishment and encloses generative marrow.

they cut two hidden channels or veins down the back where the skin and the flesh join, which answered severally to the right and left side of the body.
The Timaeus itself, in Benjamin Jowett's rendering, presents the veins as divinely engineered conduits whose decussation at the head binds skull to body, encoding a teleological anatomy of distribution and governance.

Madhya nāḍī (madhya nāḍī means, the central vein), the central vein suṣumnā, which is madhya saṁsthā, situated in the central path.
Singh's commentary identifies the Sanskrit nāḍī with 'vein,' designating the suṣumnā as the axial contemplative channel through which consciousness ascends toward Bhairava-identity.

this energy of breath neither goes out nor enters in (na vrajet na viśet) because madhye vikāsite, this central vein is vikāsite, it is already illuminated.
The passage argues that when the central vein is fully illuminated by contemplative practice, the oscillation of breath ceases and non-dual Bhairava-consciousness spontaneously manifests.

your breath goes down in the central vein, in the pathway of the central vein, then it touches mūlādhāra. From that mūlādhāra is the appearance of parā śakti.
Singh traces the meditational descent of breath along the central vein to the root cakra as the precondition for the ascending emergence of parā śakti, linking vascular metaphor to tantric energetics.

As the stream moves through the veins, the various substances composing it are attracted, like to like, by the bodily organs, whose waste they thus repair.
Plato's commentary explains how the blood's passage through veins operates by sympathetic attraction, a proto-alchemical principle in which like draws like to restore organic waste.

when the flesh becomes decomposed and sends back the wasting substance into the veins, then an over-supply of blood of diverse kinds, mingling with air in the veins, having variegated colours and bitter properties
Plato's pathology is constituted by a reversal of normal vein-circulation: corrupted flesh re-enters the veins, polluting the blood with bile, phlegm, and serum, producing systemic disease.
, Timaeus, -360supporting
But when the flesh wastes and returns into the veins there is discoloured blood as well as air in the veins, having acid and salt qualities, from which is generated every sort of phlegm and bile.
This passage encapsulates the Platonic theory of disease as a pathological inversion whereby the veins, normally channels of nourishment, become conduits of corruption.

either it is expelled all over the surface of the body, or else, after being thrust through the veins into the lower or upper belly, banished
In Plato's humoral pathology, bile expelled through the veins to body cavities represents the terminus of a diseased circulatory reversal, where the vein becomes an organ of pathological expulsion.

His crucial demonstration that the blood must circulate combines visible evidence (ligature of blood vessels so as to show the differences between veins and arteries) and quantitative mensuration.
Hillman reads Harvey's experimental differentiation of veins from arteries as the historical moment when the heart's metaphysical resonance was displaced by mechanical quantification, transforming feeling into hydraulics.
