Impermanence occupies a foundational position across the depth-psychology corpus, appearing not as a peripheral observation about change but as a primary ontological datum that orients practice, ethics, and psychological transformation. The richest sustained treatment comes from Dōgen Eihei, for whom impermanence (anitya) is neither pessimistic doctrine nor abstract principle but the living reality immediately before the eyes — the ground from which aspiration toward awakening spontaneously arises. Dōgen insists that realizing impermanence is not intellectual but visceral: its urgency scales with proximity to death, as his parable of the four horses makes precise. The Stoic tradition, represented through Marcus Aurelius and Hadot's commentary, reaches cognate conclusions by a different route: constant meditative attention to flux and dissolution serves not despair but rational equanimity, dissolving the ego's attachments to permanence without requiring any metaphysical framework. Trungpa and Cooper, writing from Tibetan and Zen perspectives respectively, situate impermanence within the deconstruction of a fixed self, linking it directly to śūnyatā and the collapse of subject-object duality. McGilchrist approaches the theme phenomenologically, diagnosing modernity's flight from mortality as a pathological denial of impermanence that paradoxically accelerates its effects. The central tension in the corpus is whether impermanence is primarily a cause of suffering to be accepted or a generative aperture through which eternity — or awakening — is encountered.
All conditioned things are impermanent (Skt. anitya) ... Impermanence and no-self are th[e unified message from the Buddha].
Dōgen presents impermanence as the first of the four Dharma seals and insists it is inseparable from no-self, duḥkha, and nirvāṇa — a unified soteriological teaching rather than an isolated doctrine.

Impermanence is truly the reality right in front of our eyes. We need not wait for some teaching from others, some proof from some passage of scripture, or some principle.
Dōgen argues that impermanence is not a doctrinal conclusion requiring scriptural proof but an immediate, perceptible fact that should motivate sustained practice.

The Buddha explained the first horse is like people who realize impermanence after someone in another village dies ... the fourth, those who do not accept impermanence until they are facing their own death.
Through the parable of the four horses, Dōgen calibrates degrees of readiness to realize impermanence, linking the speed of recognition to the proximity of death and the depth of practice.

Dōgen’s insight into impermanence is very different from these pessimistic views of the fleeting world ... realizing impermanence is sad and painful, it is also how we arouse the mind of awakening and come to perceive eternity within impermanence.
The commentary distinguishes Dōgen's reading from mournful mappō pessimism, positioning impermanence as the very threshold through which eternal awakening is encountered.

Sawaki Rōshi emphasized the quality of our eyes — whether they are open to seeing impermanence and feeling grief about the plants’ and our own lives.
Sawaki Rōshi frames the perception of impermanence as an existential capacity of vision forged through personal loss, not merely a Buddhist concept to be learned.

Both the substance themselves, we see as a flood, are in a continual flux; and all actions in a perpetual change; and the causes themselves, subject to a thousand alterations, neither is there anything almost, that may ever be said to be now settled and constant.
Marcus Aurelius presents universal flux as the cosmological ground for Stoic equanimity, arguing that attachment to permanence is the root of foolish pride and existential distress.

Whatsoever is once changed, shall never be again as long as the world endureth. And thou then, how long shalt thou endure? And why doth it not suffice thee, if virtuously ... thou mayest pass that portion of time, how little soever it be.
Marcus Aurelius uses the irreversibility of change as a Stoic memento mori, transforming the recognition of impermanence into an argument for virtuous sufficiency in the present moment.

All things in the world from all eternity, by a perpetual revolution of the same times and things ever continued and renewed, are of one kind and nature ... that life which any the longest liver, or the shortest liver parts with, is for length and duration the very same.
Marcus Aurelius argues that the sameness of impermanence across all lifespans dissolves the fear of a short life, since only the present moment can ever truly be lost.

To consider, what manner of men both for soul and body we ought to be, whensoever death shall surprise us: the shortness of this our mortal life: the immense vastness of the time that hath been before.
Marcus Aurelius prescribes regular meditation on mortality and the brevity of life as a disciplinary exercise that corrects misplaced valuation of worldly objects.

Running away from mortality, we speed its arrival. Time, however, expands, slows, and feels rich and companionable when we stop and simply attend to where we are.
McGilchrist diagnoses the modern cultural flight from mortality as a self-defeating denial of impermanence, arguing that full presence to the moment paradoxically arrests time's felt acceleration.

All parts of the world ... must of necessity at some time or other come to corruption. Alteration I should say, to speak truly and properly.
Marcus Aurelius corrects the common language of 'corruption,' insisting that impermanence is better understood as perpetual alteration — a neutral feature of universal nature rather than a defect.
, Meditations, 180supporting
Life is wearing off, and a smaller part of it is left daily ... death is continually advancing; and besides that, our understanding sometimes dies before us.
Hadot's presentation of Marcus Aurelius frames impermanence as a double urgency — the erosion of time and the prior death of reason — demanding that philosophical practice begin without delay.

We cannot infer Theon’s impermanence from the substance’s impermanence ... What does endure ... is the ‘peculiarly qualified’ individual, Theon, whose uniquely identifying characteristics must for this purpose be lifelong.
The Stoic distinction between material substrate and the 'peculiarly qualified' individual complicates simple impermanence arguments, suggesting that personal identity may persist through material flux in ways Buddhist anātman theory does not allow.

Dogen teaches that realization emerges as a penetrating experiential awareness that self is not a personal, fixed, or permanent possession.
Cooper synthesizes Dōgen and psychoanalytic thought, treating the impermanence of the self not as a cognitive belief but as a transformative experiential realization that dissolves fixed ego-structures.

Consider in my mind, for example's sake, the times of Vespasian ... and is not that their age quite over, and ended? ... how many men, after they had with all their might and main intended and prosecuted some one worldly thing or other did soon after drop away.
Marcus Aurelius employs historical panorama as a contemplative exercise in impermanence, dissolving identification with any particular era or achievement by showing each age equally annihilated by time.

The common sense approach to gain and loss is topsy turvy. Insight and enlightenment do not come from accumulation, but from simplification; not from getting but from giving up.
Brazier frames the therapeutic application of Buddhist teaching on impermanence as an inversion of Western accumulation logic, where release rather than acquisition produces genuine well-being.

How vain all things will appear unto thee when, from on high as it were, looking down thou shalt contemplate all things upon earth, and the wonderful mutability, that they are subject unto.
The 'view from above' exercise in Marcus Aurelius uses contemplation of universal mutability to induce detachment from worldly concerns, operationalizing impermanence as a specific meditative technique.
