The dyad ‘Essence and Life’ occupies one of the most contested and generative intersections in the depth-psychology corpus and its philosophical tributaries. At stake is whether life is a property that essence possesses or whether the two are so inextricably bound that their distinction is merely analytical. Plotinus, the dominant ancient voice on this question, argues with sustained force that Soul cannot merely ‘have’ life as an adventitious quality; life and substance must be a unity, or the soul’s essential being dissolves into contingency. This Neoplatonic axiom ramifies across Christian mystical theology: in the Philokalia, Palamas insists that divine life is neither identical to the divine essence nor separable from it, locating life in the uncreated energies — a resolution that deliberately holds the tension rather than collapsing it. Sri Aurobindo reformulates the same polarity in evolutionary terms, treating life as the Consciousness-Force operating between Matter and Mind, a transitional mode of a single underlying reality. The Taoist commentarial tradition (Liu I-ming) approaches the same problem through the alchemy of essence and feeling, where inner cultivation restores a primordial unity dissipated by habituated existence. Across traditions, the core tension is identical: essence risks sterile abstraction without life; life risks temporal dispersal without essence. The term thus marks a fundamental junction between ontology and psychology.
the being here must, that is, be life, and the life and the being must be one… if life is a thing possessed, the essence of the possessor is not inextricably bound up with life. If, on the contrary, this is not possession, the two, life and Substance, must be a unity.
Plotinus argues that for Soul, essence and life cannot stand in the relation of possessor to possession; they must constitute an absolute unity, or Soul’s very being is undermined.

Either life is Essential Reality, and therefore self-li[ving]… this is no case of a Matter underlying and a life brought into that Matter and making it into soul.
Plotinus distinguishes imported life from intrinsic life, arguing that soul’s immortality rests on life being identical with Essential Reality rather than adventitiously added to a substrate.

happiness can exist only in a being that lives fully… life in which the good is present as something essential not as something brought from without, a life needing no foreign substance called in from a foreign realm.
Plotinus identifies the supreme good with fullness of life that is constitutively essential rather than externally added, making essence and life co-extensive in the highest being.
, The Six Enneads, 270thesis
the supreme Intellect both is that good and surpasses goodness… Life, too, is to be found in It or, rather, the Intellect is life; for life is good a[nd transcends goodness].
Palamas, following Gregory of Nyssa, identifies the supreme Intellect with life itself, so that life is not an attribute but the very mode of being of the divine essence.
, The Philokalia, Volume 4, 1995thesis
The Being is the fundamental reality; the Becoming is an effectual reality: it is a dynamic power and result, a creative energy and working out of the Being, a constantly persistent yet mutable form, process, outcome of its immutable formless essence.
Aurobindo recasts essence and life as Being and Becoming, insisting that the Becoming is real but derivative — a creative energy proceeding from essence without exhausting it.
, The Life Divine, 1939thesis
Life is really a universal operation of Conscious-Force acting subconsciously on and in Matter… it is the same in all the stages and always a middle term between Mind and Matter.
Aurobindo positions life not as a distinct essence but as the mediating operation of Consciousness-Force, dissolving the sharp boundary between life and its metaphysical ground.
, The Life Divine, 1939thesis
we know Identity, a concept or, rather, a Life never varying, not becoming what previously it was not, the thing immutably itself… and knowing this, we know Eternity.
Plotinus equates Eternity with invariant Life in the Supreme, positioning essence as a life that is self-identical and motionless — the ontological ground of temporal life below.

in the Intellectual-Principle Itself, there is complete identity of Knower and Known… there must always be a yet higher, a principle above all such diversity. The Supreme must be an entity in which the two are one; it will, therefore, be a Seeing that lives.
Plotinus grounds the identity of essence and life in the Intellectual-Principle’s self-knowing, where being and living converge in a single act of self-presence.

All life belongs to it, life brilliant and perfect; thus all in it is at once life-principle and Intellectual-Principle, nothing in it aloof from either life or intellect: it is therefore self-sufficing and seeks nothing.
The Intellectual-Principle is presented as the sphere where life and intellectual essence are entirely co-present, demonstrating the principle’s self-sufficiency as evidence of their unity.

‘the life that the Father possesses in Himself is nothing other than the Son, and the life that is in t[he Father is the Son].’
The Philokalia marshals Cyril’s formula to show that divine life is not a property superadded to essence but is hypostatically identical with the Son — essence and life coincide in Trinitarian theology.

the Intellectual-Principle is the earliest form of Life: it is the Activity presiding over the outflowing of the universal Order… it must of necessity derive from some other Being, from one that does not emanate but is the Principle of Emanation, of Life, of Intellect and of the Universe.
Plotinus traces life back through the Intellectual-Principle to a prior source that is the unmanifest principle of both life and essence, establishing the emanative hierarchy.
, The Six Enneads, 270supporting
Being is itself an activity: there is one activity, then, in both or, rather, both are one thing. Being, therefore, and the Intellectual-Principle are one Nature: the Beings, and the Act of that which is, and the Intellectual-Principle thus constituted, all are one.
Plotinus identifies Being with Activity, collapsing the distinction between static essence and dynamic life-process into a single ontological act.

Life is the fina[l individualising operation]… Mind and Life are the same Consciousness-Force, the same Knowledge-Will, but operating for the maintenance of distinctly individual forms in a sort of demarcation, opposition and interchange.
Aurobindo presents life as the individualising phase of a unitary Consciousness-Force, making essence and life distinguishable in function but not in ultimate substance.

determined Life is Intellectual-Principle. And the multiplicity? As the multiplicity of Intellectual-Principles: all its multiplicity resolves itself into Intellectual-Principles.
Plotinus specifies that when Life is delimited it becomes Intellectual-Principle, showing that the articulation of essence is itself a form of life’s self-determination.

the energy, although distinct from the divine nature, is also an essential, that is to say, a natural activity of that nature.
Palamas distinguishes divine energy from essence while insisting the energy is natural to the essence, providing a theological grammar for relating life-activity to essential being without collapsing or severing them.

a perduring Being, the statement also of perdurance and of Eternity: perdurance is the corresponding state arising from the [divine] substratum and inherent in it; Eternity… is that substratum carrying that state in manifestation.
Plotinus links essence as substratum with the living state of perdurance it carries, showing that eternity is essence made manifest as a mode of living presence.

it is an Essence which does not come into being by finding a seat in body; it exists before it becomes also the soul of [a body].
Plotinus establishes the soul’s essence as prior to and independent of its life-giving function in body, preserving the ontological primacy of essence over any particular vital manifestation.
, The Six Enneads, 270supporting
we must go back to the state we affirmed of Eternity, unwavering Life, undivided totality, limitless, knowing no divagation, at rest in unity and intent upon it.
Plotinus characterises the Eternal realm as unwavering Life that is simultaneously undivided totality, equating the essence of eternity with a mode of life immune to temporal dispersal.

the Holy Spirit is not participated in to the same degree by each person who receives Him; rather, He distributes His energy according to the faith of the participant; for though He is simple in essence, He is diverse in His powers.
Palamas notes that divine life-energy is distributed variably while the essence remains simple, illustrating how essence and life can be united yet produce differentiated effects in creatures.

materialistic thought has always instinctively felt from the wrong or lower end of things and as spiritual knowledge working from the summit had long ago discovered… Supermind or the Truth-consciousness is the real creative agency of the universal Existence.
Aurobindo frames the identity of material force and consciousness as the hidden ground from which both life and essence spring, aligning materialist and spiritual intuitions at a deeper level.

The nature of an Ideal-form is to be, of itself, an activity; it operates by its mere presence: it is as if Melody itself plucked the strings.
Plotinus illustrates how an ideal-form, analogous to essence, generates life-activity by its mere presence rather than by external causation, exemplifying the intrinsic relation of essence to living activity.
