Neoplatonic Ochema — Soul Vehicles
Neoplatonic Ochema — Soul Vehicles is a Greek / Neoplatonic — soul vehicles (ochema) body system as transmitted through the lineage Neoplatonic authors describe the soul as using one or more vehicles (ochema) in its relation to embodiment, descent, ascent, and the intelligible order. Plotinus provides an early account of a luminous or pneumatic vehicle, while Iamblichus and Proclus develop more differentiated accounts of the vehicle's cosmic and ritual roles. This map uses three nested shells—astral, aerial, and pneumatic—as a cautious cross-author synthesis and places a henad point above the body as a symbolic source of unity.. This page lists every point in the system with sourced placements and links to cross-tradition correspondences curated for The Body Spiritual.

- Plotinus, Enneads IV.3 (On the Problems of the Soul), especially IV.3.15–24 (A. H. Armstrong (trans.), Plotinus, Loeb Classical Library, Harvard University Press, 1984) — Enneads IV.3.15–24 discusses the soul's relation to its vehicle and the conditions of embodiment and departure. The passage supports a vehicle vocabulary but does not establish the three-shell front-view model used here.
- Plotinus, Enneads IV.4 (Problems Connected with the Soul), IV.4.1–5 (A. H. Armstrong (trans.), Plotinus, Loeb Classical Library, Harvard University Press, 1984) — Enneads IV.4.1–5 treats the soul's cosmic reach and relation to sensible processes, supplying context for the luminous and aerial language of later vehicle theories. The source is philosophical cosmology, not an anatomical chart.
- Iamblichus, De mysteriis, Book V, especially V.18–23 (Emma C. Clarke, John M. Dillon, and Jackson P. Hershbell (trans.), Iamblichus: On the Mysteries, Society of Biblical Literature, 2003) — Book V discusses the soul's divine ordering and ritual ascent in response to Porphyry's questions; it is used here for Iamblichean differentiation of soul, vehicle, and divine participation, not for a single universally fixed vehicle count.
- Proclus, In Timaeum, Book III, discussions of the soul's vehicle (Thomas Taylor (trans.), The Commentaries of Proclus on the Timaeus of Plato, 1820; section numbering varies by edition) — Proclus' Timaeus commentary develops the vehicle of the soul in relation to cosmic embodiment and return. The edition's section and page numbering varies, so the Book III vehicle discussions are the locator used here.
- John F. Finamore, Iamblichus and the Theory of the Vehicle of the Soul (Scholars Press, 1985) — Finamore reconstructs the development of vehicle theory across Middle Platonism, Plotinus, Iamblichus, and Proclus; it supplies modern scholarly context for the cross-author synthesis.
Known lineage variants
- Ochema terminology is not stable across the Neoplatonic corpus. Plotinus, Iamblichus, and Proclus differ in how they describe the vehicle's substance, number, luminosity, and relation to the soul, so the three-shell sequence is a comparative synthesis rather than a single author's doctrine.
- The henad is a Proclean term for a divine unity and is not simply an anatomical point or a synonym for the human soul. It is placed above the crown as a symbolic vertical reference with broad uncertainty.
- The shells are centred on the navel for a readable body overlay, but the primary texts do not assign astral, aerial, or pneumatic vehicles to a navel or any other fixed organ. Shell scale and opacity are editorial conventions.
- Anatomical-right is x below 0.5 in this front view. No back-view projection is implied, and the overlay must not be read as a measurable astral field or as evidence about a person's post-mortem state.

Frequently asked
What is Astral vehicle?
The astral vehicle is the outer shell in this compact synthesis, representing the vehicle language associated with sensible embodiment and affective life. Plotinus does not provide this exact three-shell body layout, so the navel-centred envelope is an editorial mnemonic with wide uncertainty.
What is Aerial vehicle?
The aerial vehicle is shown as an intermediate shell for motion and mediation between sensible embodiment and the more luminous vehicle. The air tag is a symbolic cue for mobility and subtle mediation, not a claim that a discrete aerial substance can be detected in the abdomen.
What is Pneumatic vehicle?
The pneumatic vehicle is the innermost shell and represents the luminous carrier language that becomes more explicit in later Neoplatonic discussions. Its proximity to the centre is an ordering metaphor for refinement, not a claim that pneuma is a physical tissue or a fixed human organ.
What is Henad — unity beyond the vehicle?
The henad point marks unity beyond the differentiated vehicle shells in a Proclean frame. It is placed above the crown to preserve the diagram's vertical transcendence metaphor, not to imply that a henad is a human cranial structure or a personal possession.
