The term 'sphere' operates across multiple registers in the depth-psychology corpus, from cosmological archetype to psychological symbol of wholeness. In its cosmological dimension, the sphere appears as the most perfect of forms — the Platonic Demiurge fashions the world-body as a sphere precisely because it is 'the figure that comprehends in itself all the figures there are,' equidistant from centre to extremity. This Platonic inheritance passes through Neoplatonism into the theological formula preserved by von Franz: 'Deus est sphaera infinita, cuius centrum est ubique circumferentia nusquam' — God as infinite sphere whose centre is everywhere and circumference nowhere — a formula that became a primary symbol of the Self archetype in Jungian thought. Kepler's geometric mysticism, analyzed by Pauli, carries forward the spherical symbolism into the early modern scientific imagination. McGilchrist identifies the sphere-image with right-hemisphere cognition, associating its recurrence in Romantic poetry with a mode of holistic rather than analytical apprehension. Rudhyar, synthesizing Gnostic and astrological traditions, explicitly equates the perfected personality with a 'perfect sphere of being.' The tension that runs through all treatments is between the sphere as static perfection — closed, self-sufficient, needing nothing — and as dynamic symbol of the psychic totality that encompasses and integrates opposites.
'Deus est sphaera infinita, cuius centrum est ubique circumferentia nusquam' (God is an infinite sphere whose center is everywhere and whose circumference is nowhere).
Von Franz traces the pivotal medieval formula equating God with an infinite sphere — centre everywhere, circumference nowhere — as the theological precursor to the Jungian Self archetype.

For the living creature that was to embrace all living creatures within itself, the fitting shape would be the figure that comprehends in itself all the figures there are; accordingly, he turned its shape rounded and spherical, equidistant every way from centre to extremity.
Plato's Timaeus establishes the sphere as the cosmologically perfect form, the shape assigned to the World-Soul because it alone comprehends all other figures within itself.

A divine Person is a man who, although operating temporarily within a particular form, yet has so equilibrated his spiritual being that his 'body of light' is a perfect sphere of being and understanding. He has reached... the condition of 'universal Form.' In Gnostic philosophy, such a one is called Eon or Sphere.
Rudhyar identifies the sphere explicitly with the realized, universal personality — a Gnostic Aeon — in whom all partial viewpoints are harmonized into total equilibrium.

Roundness and the image of the sphere come and go with the influence of the right hemisphere. They were central to Romanticism.
McGilchrist argues that the sphere-image is a reliable marker of right-hemisphere dominance in cultural history, its appearance and disappearance tracking holistic versus analytical modes of world-apprehension.

nothing seipso melius ornatiusque, nihil praestantius repperit. Propterea cum corporeum mundum agitaret animo, formam ei destinavit sibi ipsi quam simillimam... praestantissimaque omnium figura, Sphaerica superficies.
Pauli quotes Kepler's Latin to demonstrate that the sphere — as the figure most resembling the Creator — grounds Kepler's mathematical theology and his vision of world-harmony.

The process of translation to eternity was graphically represented in antiquity by the image of ascending the ladder of the planetary spheres. When a soul is born into an earthly body it descends from heaven through the planetary spheres and acquires the qualities pertaining to each.
Edinger situates the plural planetary spheres within the soul's cosmological journey, each sphere conferring specific psychic qualities as the soul descends into incarnation or ascends toward liberation.

The earth has become a sphere poised in the midst of a sort of Chinese box of concentric spheres; not the flat disk of yore, surrounded by a cosmic sea.
Campbell traces the Hellenistic cosmological model of concentric spheres as the structural framework underlying Western mythic imagination from Ptolemy to Dante.

it can be demonstrated geometrically that the sphere whose diameter is twice that of another sphere is eight times the size of the latter, it follows that one eighth of the sphere of the element of water is contained by and merged with earth's sphere.
The Philokalia deploys spherical geometry to model the interpenetration of elemental spheres, grounding cosmological theology in rigorous geometric proportion.

Since those things on which it is located are spherical, it must encircle them unceasingly.
Patristic cosmology in the Philokalia explains celestial circular motion as a necessary consequence of the spherical form of the bodies the celestial element surrounds.

Some have thought that the heaven encircles the universe and has the form of a sphere, and that everywhere it is the highest point, and that the centre of the space enclosed by it is the lowest part.
John of Damascus summarizes competing patristic views of heaven's nature, noting the sphere as the dominant cosmological model for the heaven that encircles and encompasses all creation.

if we delimit the psyche from the physiological sphere of instinct at the bottom, so to speak, a similar delimitation imposes itself at the top.
Jung uses 'sphere' metaphorically to demarcate the psyche's lower boundary with instinct and its upper boundary with spirit, employing spatial language without developing the sphere as explicit symbol.

psychology has left the wilderness in favor of the domesticated sphere (ego country)
Giegerich deploys 'sphere' as a critical metaphor for the domesticated, ego-bounded domain of conventional psychology, contrasting it with the wilderness of genuine soul-thinking.
