Primordial Unity occupies a foundational position across the depth-psychology corpus, functioning simultaneously as cosmogonic principle, psychological origin-state, and teleological horizon. The term names that undifferentiated wholeness which precedes—and, in certain traditions, must be ritually or psychically restored after—the fall into multiplicity. Its treatment in the literature is far from uniform. Eliade reads the Brahmanic sacrifice as an explicit technology for recovering pre-cosmic unity shattered by creation itself; Nietzsche's Dionysian dissolution of the principium individuationis reaches toward the same substrate from an aesthetic-tragic direction. Plotinus provides the metaphysical architecture: the One as utterly prior to Being, generative of all yet belonging to none. Jung and his school inherit this Neoplatonic inheritance but reframe it psychologically: primordial unity becomes the unus mundus, the pre-differentiated background of psyche and matter alike, anticipated by alchemical Mercurius and approached asymptotically through the coniunctio. Neumann situates it developmentally as the uroboric state, the original psychic situation in which opposites remain undivided. The central tension in the corpus is whether primordial unity is a regressive pull toward unconscious merger or a legitimate telos of individuation—a tension that organizes much of Jung's later work and the debates between Neumann and von Franz over the nature of the unus mundus.
the sacrifice proper has another end: to restore the primordial unity, that which existed before the Creation. For Prajapati created the cosmos from his own substance
Eliade argues that Brahmanic sacrifice is explicitly oriented toward recovering the pre-cosmic unity dissolved by the act of creation, making ritual the vehicle of ontological restitution.

The Unity, then, is not Intellectual-Principle but something higher still... Generative of all, The Unity is none of all; neither thing nor quantity nor quality nor intellect nor soul
Plotinus establishes the One as the absolute primordial unity that transcends all determination and multiplicity, serving as the generative ground of all being without itself being a being.

the Mercurius of the alchemists is actually himself this unus mundus, 'the original non-differentiated unity of the world or of Being.'
Von Franz identifies the alchemical Mercurius with the unus mundus as the primordial non-differentiated unity, linking the depth-psychological concept directly to its metaphysical and alchemical antecedents.

as soon as the number two appears, a unit is produced out of the original unity, and this unit is none other than that same unity split into two and turned into a 'number.'
Jung traces the psychological and cosmological significance of differentiation from primordial unity, arguing that the emergence of the number two constitutes the first rupture from an original undivided ground.

We have designated this original psychic situation, which embraces opposites and contains male and female, conscious and anticonscious, elements in mixture, as 'uroboric.'
Neumann defines the primordial unity as the uroboric state, the original psychic condition in which all opposites—including gender and consciousness—remain undifferentiated within the Great Round.

there is only one Source, one beginning, one unity out of which all the multiplicity of this life flows, and to which it returns
Johnson translates the theological claim of divine unity into a psychological axiom, arguing that depth work presupposes a single source from which multiplicity emanates and toward which it tends.

This psyche corresponds to the collective unconscious, which, itself of unitary nature, is represented by the unitary Primordial Man.
Jung equates the Manichaean Primordial Man—himself a figure of primordial unity—with the collective unconscious, grounding the mythological concept in analytical psychology.

the whole universe is one with its Creator, as an army with its commander... The world appears as the corpus mysticum of God
Jung cites Pico della Mirandola's threefold unity to illustrate the pre-modern conception of a cosmos organically unified with its divine source, a philosophical anticipation of the unus mundus.

the primordial idea has become a symbol of the creative Jungian of opposites, a 'uniting symbol' in the literal sense
Jung traces how the archaic hermaphrodite image evolved from a relic of primordial undifferentiation into an active uniting symbol that mediates the tension of opposites.

nowhere is there any future, for every then is a now; nor is there any past, for nothing there has ever ceased to be; everything has taken its stand for ever
Plotinus describes the Intellectual-Principle's mode of existence as a timeless simultaneity that mirrors the condition of primordial unity, in which temporal succession collapses into an eternal present.

the One Mind is the unconscious, since it is characterized as 'eternal, unknown, not visible, not recognized.'
Jung identifies the Tibetan Buddhist One Mind with the unconscious, reading Eastern doctrines of primordial unity as psychological descriptions of the pre-ego substrate.

The common background of microphysics and depth psychology is as much physical as psychic and therefore neither, but rather a third thing, a neutral nature which can at most be grasped in hints since its essence is transcendental.
Von Franz characterizes the unus mundus as a transcendental third beyond psyche and matter, the neutral ground of primordial unity that contemporary science can only approach asymptotically.

the hermaphroditic character of the Primordial Child gained acceptance when the ideal of the nymph-like boy appeared in Greek culture. It is as though this were only the recrudescence of the bisexual Primordial Child in secularized form.
Jung and Kerényi identify the bisexual Primordial Child as the mythological carrier of primordial unity before sexual differentiation, a figure whose recurrence marks the persistence of pre-differentiated wholeness in culture.

There is no better way of cultivating human nature and life than to bring both back to unity.
Wilhelm's transmission of Taoist teaching presents the restoration of primordial unity as the supreme aim of spiritual cultivation, converging with depth-psychological notions of individuation as return to wholeness.

Life as it emerges in our material universe, an energy of the dividing Mind subconscious, submerged, imprisoned in Matter... is only a dark figure of the divine superconscient Force
Aurobindo frames material existence as a diminished reflex of a divine superconscient unity, employing an emanationist schema parallel to the depth-psychological understanding of consciousness as derivative of a primordial whole.

As he mingled the living water with the turbid, darkness entered the light.
Jonas documents the Gnostic-Mandaean mythology of mixture, in which primordial unity is disrupted by the violent commingling of light and darkness, establishing the soteriological need for separation and return.
