Purity occupies a remarkably diverse terrain in the depth-psychology corpus, functioning simultaneously as a metaphysical aspiration, a psychological discipline, and a contested theological ideal. The term is not deployed uniformly but is calibrated to the framework within which each thinker operates. In the Philokalic and hesychast traditions, purity is primarily a condition of the intellect (nous): the eradication of impassioned thoughts that obstruct the soul’s illumination by divine light, with Makarios insisting that ‘purity of heart can be brought about only by Jesus.’ Epictetus repositions purity as an epistemological matter — the soul’s freedom from ‘bad judgments’ — anticipating cognitive-psychological readings. Sri Aurobindo bifurcates the term, distinguishing the eternally pure spirit from the instruments of mind and heart that require purification as a precondition for concentrated divine action. Hillman, reading through alchemical psychology, treats purity as the telos of refinement: the removal of extraneous admixtures to reveal a metal’s essential nature — a depth-psychological metaphor for soul-making through discipline rather than moralistic cleansing. Zimmer locates purity in the Samkhya-Yoga concept of sattva, the transparent guṇa that, when isolated, becomes the condition for enlightenment itself. Across these traditions a persistent tension emerges: whether purity is achieved through ascetic subtraction, contemplative concentration, ethical rectification, or alchemical transformation — and whether the self that achieves purity is the same self that required cleansing.
The whole Old and New Testaments speaks of purity, and everyone, whether Jew or Greek, should long for purity even though not all can attain it. Purity of heart can be brought about only by Jesus
St. Makarios establishes purity of heart as the universal soteriological goal of Scripture, attainable not by human effort alone but only through Christ’s transforming presence.

the purity of the soul is the planting in it of proper opinions; and the soul is pure which has proper opinions, for the soul alone in her own acts is free from perturbation and pollution.
Epictetus redefines purity as an epistemological and volitional condition — the presence of correct judgments — rather than a ritual or bodily state, making it entirely within the soul’s own domain.
, Discourses, 108thesis
Purity: the least possible extraneous admixtures. Purity: entirely self-same. The refined metal is unadulterated; the sophisticated metal has been reduced to its essential qualities.
Hillman defines purity alchemically as the reduction of a substance to its essential nature through disciplined refinement, transposing the concept from moral theology into the language of soul-making through process.
, Alchemical Psychology, 2010thesis
the spirit, the divine Reality in man stands in no need of purification; it is for ever pure, not affected by the faults of its instrumentation or the stumblings of mind and heart and body
Aurobindo distinguishes the eternally pure spirit from the psycho-physical instruments that require purification, framing purification as instrumental preparation rather than the transformation of the ground of being.
, The Synthesis of Yoga, 1948thesis
Purity and concentration are indeed two aspects, feminine and masculine, passive and active, of the same status of being;
Aurobindo presents purity and concentration as complementary, gender-inflected polarities constituting a single integral state of being, essential to spiritual perfection.

sattva, accordingly, ‘the ideal state of being; goodness, perfection, crystal purity, immaculate clarity, and utter quiet.’ The quality of sattva predominates in gods and heavenly beings, unselfish people, and men bent on purely spiritual pursuits.
Zimmer identifies sattva as the Sanskrit philosophical equivalent of purity — a constitutive quality of prakṛti whose dominance enables enlightenment by making consciousness transparent to the self.

‘Blessed are the pure in heart, for they shall see God’ (Matt. 5:8) for He is hidden in the hearts of those who believe in Him. They shall see Him and the riches that are in Him when they have purified themselves through love and self-control; and the greater their purity, the more they will see.
Maximos the Confessor grounds purity in the Beatitudes, presenting it as a graduated condition of vision: the degree of purity directly determines the degree of divine perception available to the intellect.

We must not therefore expend all our effort in bodily fasting; we must also give attention to our thoughts and to spiritual meditation, since otherwise we will not be able to advance to the heights of true purity and chastity.
Cassian subordinates bodily asceticism to the purification of thought, insisting that interior attention to the intellect is the indispensable route to genuine purity and chastity.

The greater your purification, the more you will be granted His illumination.
The Philokalia presents purification as causally proportionate to divine illumination, establishing a direct soteriological economy between the soul’s cleansing and its capacity to receive God.

Cleansed of the whirling dust of passion that normally bedims the inner atmosphere… the material of nature and its innate vital force becomes entirely sattva: calm, transparent, a mirror unobscured by film, a lake without a ripple, luminous in its crystalline repose.
Zimmer renders yogic purification as the progressive elimination of rajas and tamas until prakṛti becomes wholly sattvic — a luminous, mirror-like transparency that allows the puruṣa to be recognized.

By the practice of cleanliness, śauca, say the commentators, attraction to the opposite sex evaporates, as it does by the contemplation of the realities of the body.
Bryant’s commentary on Patañjali shows how bodily cleansing (śauca) functions as a psychological discipline that dissolves erotic projection by replacing idealization with direct perception of the body’s material reality.

each soul in prayer is stirred and shaped in accordance with the measure of its purity. It loses sight of earthly and material things
Cassian articulates a psychodynamic principle: the quality of contemplative prayer is directly calibrated to the soul’s degree of purity, making purity the formal condition of authentic mystical ascent.

disciplined purity; courage of the majestic face; gravity; modesty that goes fearless and tranquil and passionless
Plotinus enumerates disciplined purity among the hueless, non-sensory virtues that constitute the soul’s inner beauty, placing it within the Neoplatonic hierarchy of values transcending material form.

crimes they have committed, they are condemned to a series of earthly existences until such time as they have purified themselves.
Edinger documents the Empedoclean-Orphic model in which purity is the telos of metempsychosis: successive incarnations constitute a progressive cathartic process culminating in the soul’s liberation.

‘The purity of the harmonious consciousness of the Brāhman who has directly experienced the second or so-called ‘Honeyed Stage’ is observed by those in high places, and they seek to tempt him’
Zimmer’s Yoga Sūtra commentary notes that the yogī’s achieved purity of sattvic consciousness itself becomes a target of celestial temptation, marking purity as a threshold stage rather than a final arrival.

the purity of the gospel revelation from contamination by false belief and practice. Against the ‘human and demonic doctrines’ of his opponents, Tertullian held up the rule of faith
King shows how Tertullian deploys purity as a polemical-ecclesiological category, using the language of contamination and integrity to establish apostolic truth against heretical deviation.

Edinger’s Orphic passage frames the soul’s liberation — implied but truncated — as the culmination of a purificatory cycle of reincarnations, freedom being the reward of completed catharsis.

the intellect, while still passion-dominated, cannot be united to God. Thus so long as the intellect when praying remains in a passion-charged state, it will not obtain mercy
This Philokalic text implies the necessity of purity by its negative: passion-domination in the intellect constitutes the precise obstacle to divine union, making purity the formal precondition for theosis.
