The term 'Eternal' occupies a commanding position across the depth-psychology corpus, functioning simultaneously as an ontological category, a psychological aspiration, and a cosmological ground. Plotinus furnishes the most technically rigorous treatment: Eternity is not extended time but the changeless Life of the Intellectual Principle, identical with the divine substrate itself, and accessible through that which is 'Eternal within the self.' This Neoplatonic lineage flows into Aurobindo, for whom the eternal is the self-existent ground of Sachchidananda — the immovable support beneath temporal becoming. John of Damascus theologizes the term within Trinitarian and creaturely frameworks, arguing that the eternal generation of the Son entails co-eternity with the Father, while distinguishing eternity from time as the proper 'interval co-extensive' with divine being. Nietzsche's Zarathustra redirects the eternal into the doctrine of Eternal Recurrence, celebrating it as erotic and cosmological affirmation rather than static perfection. Eliade maps the term onto archaic religion's 'eternal return' — ritual re-entry into primordial sacred time. Jung, in the Red Book, inscribes the eternal within each present moment of being, dissolving the opposition between transience and permanence. The central tension across these positions concerns whether the Eternal is a transcendent substrate beyond time, an immanent depth within every moment, or a rhythmic pattern of cyclical recurrence structuring human existence.
Eternity [the Principle as distinguished from the property of everlastingness] is that substratum carrying that state in manifestation. Eternity, thus, is of the order of the supremely great; it proves on investigation to be identical with God.
Plotinus argues that Eternity is not mere everlastingness but the divine substratum itself in its self-manifesting perdurance, making it ontologically identical with God.

We know it as a Life changelessly motionless and ever holding the Universal content [time, space, and phenomena] in actual presence; not this now and now that other, but always all.
Plotinus defines Eternity as a perfectly complete, undivided Life that contains all temporal content simultaneously, distinguished categorically from sequential time.

Authentic-Existence is measurable not by time but by eternity; and eternity is not a more or a less or a thing of any magnitude but is the unchangeable, the indivisible, is timeless Being.
Plotinus distinguishes Eternity from all quantitative or temporal measure, identifying it as the indivisible mode of authentic existence.

Oh how should I not lust for eternity and for the wedding ring of rings — the Ring of Recurrence! … for I love you, O Eternity! For I love you, O Eternity!
Nietzsche's Zarathustra recasts Eternity not as static transcendence but as the ecstatic affirmation of Eternal Recurrence, figured as erotic and creative longing.

He is the moment of the world, the eternal moment… You, being, are eternal in each moment. What is length and brevity? What is the moment and eternal duration?
Jung's Red Book locates Eternity not in a transcendent realm but in the depth of each present moment of conscious being, dissolving temporal succession into ontological presence.
, The Red Book: Liber Novus, 2009thesis
The festal calendar everywhere constitutes a periodical return of the same primordial situations and hence a reactualization of the same sacred time… the eternal repetition of paradigmatic gestures.
Eliade argues that archaic religious practice institutes the Eternal as a cyclical pattern of ritual return to primordial sacred time, structuring human existence against profane temporality.

Where a father is the source of being, there also is birth; and further, where the Source of being is eternal, the birth also is eternal: for since birth comes from the source of being, birth which comes from an eternal Source of being must be eternal.
John of Damascus develops a logical argument for the co-eternity of Son and Father, making Eternity a necessary relational property that flows from the eternal generative ground.

Age is to things eternal just what time is to things temporal… God, Who alone is without beginning, is Himself the Creator of all things, whether age or any other existing thing.
John of Damascus systematizes the distinction between temporal and eternal orders, positing 'age' as the eternal analogue of time and God as the uncreated source of both.

Age is to things eternal just what time is to things temporal… God is spoken of as aiōnios and proaionios, for the age or aeon itself is His creation.
John of Damascus differentiates the eternal divine nature from creaturely temporal existence, with even 'aeon' itself positioned as a divine creation rather than co-equal with God.

Form in itself, World in itself are eternal. From the non-manifestation they return inevitably into manifestation; they have an eternal recurrence if not an eternal persistence.
Aurobindo argues that cosmic forms possess eternal status through recurrence even where not continuously manifest, grounding Maya within the eternal truth of Self-being.

The eternal persistence or, if you will, the eternal recurrence of the manifestation in Time is a proof that the divine multiplicity is an eternal fact of the Supreme beyond Time.
Aurobindo uses the necessary recurrence of multiplicity in time as evidence that the Many are as eternal as the One, resisting exclusive monism.

Once they have reached it they are granted rest from all movement whatsoever, as there is no longer any time or age through which they need to pass. For after passing through all things they will come to rest in God, who exists before all ages.
The Philokalia presents the Eternal as the eschatological goal of contemplative ascent — the cessation of temporal movement in God who precedes all ages.

The Father eternal, the Son eternal, the Holy Ghost eternal. And yet not three Eternals, but one Eternal.
Jung cites the Athanasian Creed's formulation of Trinitarian co-eternity as a theological datum within his psychological examination of the Western God-image.

It is Sachchidananda for whose delight universal Nature displays the eternal procession of her works… an unwounded Delight, a pure and perfect Presence, an infinite and self-contained Power.
Aurobindo presents the Eternal as the Sachchidananda ground whose infinite delight occasions the perpetual cosmic procession, unaffected by temporal struggle.

Such men are in a state of freedom, because they have lost the fear of pain or hell, and the hope of reward or heaven, and are living in pure submission to the eternal Goodness, in the perfect freedom of fervent love.
James documents the mystical surrender to the Eternal as a lived psychological state of freedom, transcending calculative religion through pure self-abandonment to the Good.

If 'the backbone of fractals' is 'feedback and the iterator,' this may be at the heart of what Mircea Eliade called 'the myth of the eternal return.' Could iteration and the eternal return be referring to the same thing?
Ulanov draws a structural parallel between mathematical iteration in chaos theory and Eliade's eternal return, proposing that the mythic eternal and the dynamical are cognate patterns.

Those who have abandoned the delights of this age in the hope of enjoying the blessings of eternity, the intellect, because of its freedom from worldly cares, is able to act with its full vigor and becomes capable of perceiving the ineffable goodness of God.
Gregory Palamas argues that renunciation of temporal delights liberates the intellect to perceive eternal goodness, linking the Eternal to apophatic contemplative purification.

He is from the Eternal, and yet has always been; He is not ingenerate, yet never was non-existent; since to have always been transcends time, and to have been born is birth.
John of Damascus holds that the Son's eternal generation transcends temporal categories entirely, such that 'always having been' surpasses the very framework of time.

Grace dwells in the eternal realm of the luminary Harmozel, who is the first angel. There are three other realms with this eternal realm: grace truth form.
The Gnostic Apocryphon of John deploys 'eternal realm' as a technical cosmological term for the luminous aeons within the pleroma, structuring divine emanation spatially and temporally.

Time is right at the core of our being: not an incidental, perhaps lamentable, aspect of the human condition, that in a better-ordered world would not — does not, according to Plato — exist.
McGilchrist, drawing on Heidegger and Merleau-Ponty, counterposes the constitutive role of temporality in human consciousness against the Platonic-eternal framework, implicitly challenging transcendentalist accounts of the Eternal.

The integral perfection can come only by a mounting ascent of the lowest into the highest and an incessant descent of the highest into the lowest till all becomes one at once solid block and plastic sea-stuff of the Truth infinite and eternal.
Aurobindo uses 'eternal' adjectivally to characterize the ultimate Truth-ground toward which integral yoga ascends, without here elaborating its ontological structure.
