Across the depth-psychology corpus, 'manifold' operates on at least three distinct registers that intersect and occasionally collapse into one another. In the Neoplatonic lineage, most fully articulated by Plotinus, the manifold designates the ontological condition of multiplicity that necessarily presupposes a prior unity: every manifold is derivative, a falling-away from The One into differentiated being, yet also the vehicle through which the One becomes intelligible to itself. This metaphysical grammar was absorbed, often tacitly, by Jung and his successors. In Jung's own usage—most visibly in The Red Book and in the Seven Sermons passages embedded within Memories, Dreams, Reflections—the manifold names the irreducible plurality of the psychic world: the gods are many, the soul is many, the outer and inner worlds are each 'manifold in essence,' and the solitary thinker must negotiate between proximity and distance to that plurality without being torn apart by it. Hillman and Berry, working from archetypal premises, reprise the tension between polymorphous multiplicity and synthetic unity, tracing it through Freudian developmental theory as well as through mythic imagery. Campbell's deployment of the term in the Bhagavad Gita episode frames the manifold as the cosmic theophany itself—the whole universe in its manifold divisions concentrated within the divine body. The persistent tension in the corpus is thus between the manifold as problem (requiring reduction to unity) and the manifold as irreducible value (requiring participation rather than resolution).
a thing must be either one thing or more than one, manifold: and if there is to be a manifold there must be a precedent unity. To talk of a manifold is to talk of what has something added to unity
Plotinus establishes the foundational ontological argument that the manifold is logically and metaphysically secondary to unity, being constituted as multiplicity only by the addition of something to a prior One.

the manifold, there must be The One, that from which the manifold rises: in all numerical series, the unit is the first... its product will in its own nature be manifold and dependent upon it
Plotinus argues that any manifold of activities or entities necessarily derives from and depends upon a prior simple unity, and that the manifold's dependence on The One is the structural condition of all emanated being.

how is it the source of the manifold? A single, unmanifold emanation we may very well allow- how even that can come from a pure unity may be a problem, but we may always explain it on the analogy of the irradiation from a luminary
Plotinus confronts the paradox of how the simplex One can generate the manifold without itself becoming multiple, resolving it through the analogy of luminous irradiation that does not diminish its source.

Just as you become a part of the manifold essence of the world through your bodies, so you become a part of the manifold essence of the inner world through your soul. This inner world is truly infinite, in no way poorer than the outer one.
Jung posits a structural symmetry between outer and inner worlds as equally manifold essences, with the soul functioning as the mode of participation in the inner manifold precisely as the body participates in the outer.
, The Red Book: Liber Novus, 2009thesis
He loathes manifold diversity if it is near him. He looks at it from afar in its totality... close at hand the manifold and complicated tear and break through the silvery splendor.
Jung describes the solitary's necessary distance from the manifold as a psychic condition: proximity to manifold diversity destroys the integrating vision that only distance permits, revealing the manifold as simultaneously compelling and destructive.
, The Red Book: Liber Novus, 2009thesis
the soul, even the collective soul for all its absence of part, is a manifold: it has diverse powers- reasoning, desiring, perceiving- all held together by this chain of unity.
Plotinus demonstrates that even soul, despite its relative simplicity, is itself a manifold of powers, and its unity is participatory rather than absolute, distinguishing it from The One.

the gods are many, whilst men are few. The gods are mighty and can endure their manifoldness... men are weak and cannot endure their manifold nature.
In the Seven Sermons passage, Jung draws a crucial asymmetry: divine being sustains manifoldness naturally, whereas human psychic constitution is endangered by the same plurality that requires communal life as compensation.

Behold my forms by the hundreds and the thousands-manifold and divine, various in shape and hue... the whole universe, with its manifold divisions, all gathered
Campbell's citation of the Bhagavad Gita deploys the manifold as the signature of theophany itself—the divine revealing its fullness precisely as inexhaustible multiplicity concentrated within a single cosmic body.

These instincts were originally various and numerous and came from manifold sources. Their aim was unity, synthesis... Pre-gender sexuality is something past. Manifold and numerous sexuality was true of us once
Berry identifies the Freudian narrative of development as a teleological movement from original manifold polymorphous instinct toward synthetic genital unity, reading this as a fantasy with ideological investments in suppressing multiplicity.

wind and thunder constantly together; hence there are manifold movements and experiences, from which fixed rules are derived, so that a unified character results.
The I Ching commentary treats manifold movements and experiences as the temporal raw material from which a unified character is derived through duration, paralleling the Neoplatonic logic of unity emerging from multiplicity.

Wilhelm's I Ching translation presents the manifold as temporal experiential flux that character-formation distills into unified rule, echoing the broader corpus logic of reduction from many to one.
