The term 'Life Force' occupies a contested and layered position in the depth-psychology and perennial-philosophy corpus, ranging from Aurobindo's expansive metaphysical treatment to the philological precision of Claus's pre-Platonic Greek soul-words. Aurobindo treats the Life Force as a dynamic expression of one universal Conscious-Force—a middle term between Mind and Matter, neither reducible to brute mechanism nor separable from Spirit. Across 'The Life Divine' and 'The Synthesis of Yoga,' he maps the Life Force as an evolving cosmic principle that builds, maintains, and destroys material forms while containing, in latent or active register, the very consciousness it appears to suppress. Claus, by contrast, reconstructs the semantic archaeology of the Greek 'aion,' 'ker,' and 'psyche,' demonstrating that 'life-force' as a category predates its conceptual articulation and constitutes the primary, not derived, identity of these Homeric soul-words. The tensions in the corpus are thus multiple: between Life Force as universal Energy and as individual vitality, between its subconscious operation and its potential spiritual revelation, and between its role as creative affirmation and as the source of ego-driven suffering. The supramental transformation in Aurobindo's system promises a resolution in which the life-force is 'supravitalised' and made transparent to the spirit behind it—a promise that gives the term its particular eschatological weight in integral philosophy.
Mind-Energy, Life-Energy, material Energy are different dynamisms of one World-Force. Even when a form appears to us to be dead, this force still exists in it in potentiality although its familiar operations of vitality are suspended
Aurobindo asserts that the Life Force is not a discrete entity but one mode of a single universal Conscious-Force, persisting even in apparently dead matter as latent potential.

Life is nothing else than the Force that builds and maintains and destroys forms in the world; it is Life that manifests itself in the form of the earth as much as in the plant that grows upon the earth
Aurobindo defines the Life Force as the universal creative-destructive principle underlying all material forms, not limited to biological organisms.

it is by opening this other level or depth of experience within and by admission to the vital consciousness and vital sense that the mind can get the true and direct experience… the supramental transformation supravitalises the vital, reveals it as a dynamics of the spirit
Aurobindo argues that the Life Force can only be truly known through supramental transformation, which reveals it as a spiritual dynamic rather than a merely vital phenomenon.
, The Synthesis of Yoga, 1948thesis
Life is really a universal operation of Conscious-Force acting subconsciously on and in Matter; it is the operation that creates, maintains, destroys and re-creates forms or bodies
Aurobindo identifies the Life Force as a subconscious operation of Conscious-Force within Matter, passing through three evolutionary stages toward conscious mentality.

'Life-force' is wholly satisfactory in (1) and (2), even obligatory in the latter… the concrete manifestation of aiwv as 'marrow' appears to be secondary to the intangible sense of 'life-force' both chronologically and in importance
Claus demonstrates philologically that 'life-force' is the primary, not derived, meaning of the Greek aion, grounding the concept in archaic semantic usage predating its abstraction.

psyche has a relatively consistent 'life-force' identity from Homer on in popular usage and that this identity cannot readily be explained by post-Homeric analogy to any one of the related words
Claus argues that psyche carries a stable 'life-force' identity across Homeric and post-Homeric usage, constituting an independent semantic strand irreducible to later philosophical elaborations.

Life-Force also in the material world seems to be more dynamic and effective than Mind; our Mind is free and fully powerful in idea and cognition only: its force of action, its power of effectuation outside this mental field is obliged to work with life and matter as instruments
Aurobindo positions the Life Force as dynamically superior to mental power in the material domain, operating as the primary instrument of world-effectuation.

what it is pushed by Nature to aim at is not self-preservation alone, but life-affirmation and life-satisfaction, formulation of life-force and life-being
Aurobindo identifies the Life Force as the drive behind ego-assertion and vital self-affirmation, distinguishing it from mere survival instinct and linking it to the pathological expressions of vital nature.

its ability to be felt as the familiar archaic 'life-force' in death contexts, devoid of religious overtones, can account surprisingly well for the relative movement of all the 'soul' words between Homer and Euripides
Claus shows that the archaic 'life-force' meaning of psyche and related soul-words explains the historical semantic drift of these terms from Homer through Euripides.

Drawing on Upanishadic imagery, Aurobindo presents the Life Force and body as mutually consuming and sustaining one another, enacting the cosmic law of interchange.

Life as it emerges in our material universe, an energy of the dividing Mind subconscious, submerged, imprisoned in Matter, Life as the parent of death, hunger and incapacity, is only a dark figure of the divine superconscient Force whose highest terms are immortality, satisfied delight and omnipotence
Aurobindo frames the Life Force in its material manifestation as a fallen, obscured version of a divine superconscient Force, whose evolution aims at recovering its original transcendence.

so 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 locates Life as the individualising operation of universal Consciousness-Force, parallel to Mind, differentiating forms while remaining grounded in unity.

Desire is the lever by which the divine Life-principle effects its end of self-affirmation in the universe and the attempt to extinguish it in the interests of inertia is a denial of the divine Life-principle
Aurobindo rehabilitates desire as the operative instrument of the divine Life Force, arguing that its suppression constitutes a denial of creative existence rather than a spiritual achievement.

the proper function of the life, the vital force, is enjoyment and possession, both of them perfectly legitimate, because the Spirit created the world for Ananda
Aurobindo grounds the vital or life force in the spiritual purpose of Ananda, affirming its proper function as enjoyment and possession rather than treating it as inherently corrupt.

it attaches immense importance to the satisfaction and fulfilment of the life-being, the life-force, the vital nature: it looks on physical existence as a field for the life-impulses' self-fulfilment
Aurobindo describes the life-soul as the locus of vital identity that values the life-force and its impulses as the primary measure of earthly existence.

so great is the vim, the clutch of that more agitated Life-Will, so immense the peril of its passions and errors, so subtly insistent or persistently invasive… that even the saint and the Yogin cannot be sure of their liberated purity
Aurobindo describes the Life-Will as a tenacious force whose passions and errors resist even advanced spiritual discipline, underscoring the Life Force's power to subvert higher attainment.

of itself it will act with greater force, but still according to our imperfect nature and mainly by the drive and direction of the life-power in us and not according to the law of the highest spiritual existence
Aurobindo cautions that the Shakti operating through the life-power, without higher guidance, follows the drive of imperfect vital nature rather than spiritual law.

The second is vital, — an emerging consciousness is half-apparent as power of life and process of the growth, activity and decay of form, it is half-delivered out of its original imprisonment
Aurobindo situates the Life Force as the second of three evolutionary stages, representing a partially emergent consciousness still bound by its original material imprisonment.

Life is an action of Conscious-Force of which material forms are the result; Life involved in those [material forms]
Aurobindo briefly reiterates his core formula that Life is Conscious-Force in action, whose results are material forms, as a transitional argument toward the nature of Matter.
