The term ‘Essence’ traverses the depth-psychology corpus along several distinct but intersecting axes. In the Neoplatonic register, Plotinus establishes Essence (ousia, Real-Being) as the impartible, interval-free ground of Intellectual existence, set in deliberate contrast to the divisible magnitudes of sense: it is that which neither receives accession nor admits partition, the very substrate of Eternity. This metaphysical priority of Essence over generation and material manifestation resonates through the entire tradition that descends from him. Within the patristic and hesychast streams — John of Damascus, Gregory Palamas as rendered in the Philokalia — Essence becomes the site of theology’s sharpest tension: God’s essence is absolutely inaccessible, yet divine energies proceed from it and are genuinely participated; the distinction between essence and energy is thus not a scholastic nicety but the ground of deification and the refutation of both Eunomian rationalism and Akindynian reductionism. Descartes introduces the Scholastic question of the identity of essence and existence in God, a move that reverberates into modern ontology and, indirectly, into depth psychology’s concern with being versus becoming. Plato’s Philebus situates essence as the telos toward which all generation is oriented, linking the term to teleology and value. Across these positions the common stake is clear: what a thing irreducibly is, prior to its accidents, its relations, and its temporal unfolding — and whether that ground can ever be known, participated, or only negatively circumscribed.
to that order is opposed Essence [Real-Being]; this is in no degree susceptible of partition; it is unparted and impartible; interval is foreig
Plotinus defines Essence as Real-Being absolutely opposed to the divisible magnitudes of the sensible realm, establishing its impartible, unextended character as the hallmark of Intellectual existence.

all things instrumental, remedial, material, are given to us with a view to generation, and that each generation is relative to, or for the sake of, some being or essence, and that the whole of generation is relative to the whole of essence.
Plato establishes essence as the teleological end toward which all generation is ordered, making it ontologically prior to and more real than the processes that point toward it.
, Philebus, -360thesis
created things manifest wisdom, art and power, but not essence. Thus the divine energy made manifest by created things is both uncreated and yet not God’s essence
Palamas, via St Basil, argues that divine energies knowable through creation are genuinely uncreated yet categorically distinct from the divine essence, which remains wholly inaccessible.
, The Philokalia, Volume 4, 1995thesis
God is supra-essential essence, in which can be seen only relation and activity or creation, and these two things do not produce in His essence any composition or change.
Gregory Palamas characterises God as ‘supra-essential essence,’ insisting that divine relational and creative attributes introduce no composition or alteration into the divine essence itself.
, The Philokalia, Volume 4, 1995thesis
since there are many attributes, the one essence will be many essences; and that thing which is one in essence will be many in essence, and therefore will have many essences. But if it is one and also has many essences, it is necessarily composite.
Palamas exposes the contradiction latent in identifying divine attributes with the divine essence, showing that such identification would fracture simplicity into a composite of many essences.
, The Philokalia, Volume 4, 1995thesis
Essence, then, is common as being a form, while subsistence is particular. It is particular not as though it had part of the nature and had not the rest, but particular in a numerical sense, as being individual.
John of Damascus distinguishes essence as the universal form shared by all subsistences of the same kind, while subsistences differ only numerically and through their characteristic accidents, not in essence.
, Saint John of Damascus Collection, 2016thesis
its essence does not comprise all that makes it Soul; its individuality will determine it; a part of Soul will be essence, but not Soul entire.
Plotinus examines whether Soul’s essence is exhausted by a single characterisation, arguing that soul-essence must encompass all primary constituents and be identified with life itself, not merely contain it.
, The Six Enneads, 270thesis
in God there is no distinction between essence and existence. Therefore we can look for an efficient cause in connection with God… this formal cause bears a marked analogy to an efficient cause, and can therefore be termed a quasi-efficient cause.
Descartes argues that God’s identity of essence and existence means that the ground of divine being is formal rather than efficient, introducing what he calls a ‘quasi-efficient cause’ rooted in essence itself.
, Meditations on First Philosophy, 2008thesis
a person does not participate in God either according to His essence or according to His hypostases, for neither of these can be in any way divided, nor can they be communicated to any one at all.
Palamas insists that participation in the divine is participation in energy, not in essence or hypostasis, both of which are absolutely incommunicable and indivisible.

we have not apprehended the essence of the soul even when we have learnt that it is incorporeal and without magnitude and form: nor again, the essence of the body when we know that it is white or black, but only the attributes of the essence.
John of Damascus argues that knowledge of attributes never yields knowledge of essence itself, establishing a strict limit on both theological and psychological self-knowledge.

where all is unvaried self-identity we call it Repose… we know it as, at once, Difference and Identity when we recognize that all is unity with variety… we sum all into a collected unity once more, a sole Life in the Supreme
Plotinus identifies the Intellectual Essence as an eternal self-identical Life that contains difference and identity simultaneously, providing the model against which temporal, divided existence is measured.

self-existing reality, without distinction between the total thing and its essence— the being is a unit and is sovereign over itself; neither the being nor the essence is to be referred to any extern.
Plotinus describes the First Principle as a reality in which being and essence are strictly identical and self-grounding, requiring no external reference for either its existence or its character.

Either life is Essential Reality, and therefore self-li[ving]
Plotinus argues that soul’s life cannot be an adventitious property but must be identified with Essential Reality itself, providing the basis for the soul’s immortality.

just as one cannot say that God’s existence is created and at the same time affirm that His being is uncreated, so also one cannot say that God’s energy is created and at the same time affirm that His power to act and create is uncreated.
Palamas draws a structural parallel between the relation of existence to being and the relation of energy to essence, arguing that the uncreated status of divine power entails the uncreated status of divine energy distinct from essence.

God’s existence can no more be separated from his essence, than the existence of a triangle from its essence.
Descartes’s interlocutor accepts the mutual inseparability of essence and existence in God, comparing it to the necessary properties of mathematical figures and pressing toward a fully ontological argument.

generation in Him is without beginning and everlasting, being the work of nature and producing out of His own essence, that the Begetter may not undergo change
John of Damascus distinguishes eternal divine generation — which proceeds from essence and involves no change — from temporal creation, grounding the Son’s co-eternity in the impassible fecundity of the divine essence.

no one who enjoys the divine radiance can participate in the essence of the Creator. For there is absolutely no creature that possesses the capacity to perceive the Creator’s nature.
Palamas insists on the absolute transcendence of the divine essence, maintaining that even mystical participation in divine light does not constitute participation in essence.

the essence of all beings is earth, the essence of earth is water, the essence of water are the plants, the essence of the plants is man, the essence of man is speech
The Vedic cosmological chain cited by Govinda deploys ‘essence’ as the innermost generative principle linking each level of being to the next, culminating in speech as the human essence — a convergent but non-Western usage of the term.

This hexagram represents seeking feeling through essence; it follows on the previous hexagram of humility.
The Taoist commentary employs ‘essence’ as the interior principle through which genuine feeling is accessed, paralleling the depth-psychological notion of an underlying ground from which authentic experience arises.

true yin and yang, essence and feeling, join together, no longer blocked by false yin and yang.
In Taoist alchemical vocabulary, ‘essence’ is the yang principle whose union with feeling (yin) constitutes the completion of interior work, offering a cosmological parallel to individuation.
