Purification stands at one of the most generative crossroads in depth-psychological and comparative religious thought, where ritual, cosmology, and psychic transformation converge. The corpus reveals at least four distinct registers in which the term operates. In classical Greek religion, as Burkert and Rohde document exhaustively, purification — katharmos — is a techno-ritual affair: water, blood, fire, and torch serve to remove miasma from the polluted individual or community, restoring access to the sacred and mediating initiation. Rohde pushes further, showing how the kathartic priest and the philosophical tradition share a common grammar: the soul itself must be purified across cycles of rebirth, a theme traceable through Orphism, Pythagoreanism, and Empedocles into Platonic philosophy. Edinger then reads this gradient — from ritual impurity through moral failing to metaphysical stain — as anticipating the psychological concept of individuation. The alchemical literature, interpreted by von Franz, Abraham, and Moore after Ficino, translates purification into the opus: calcination, ablution, and dealbatio are the laboratory equivalents of psychic cleansing, separating the subtle from the gross. Pargament anchors the term sociologically, demonstrating its universality across faith traditions as a coping mechanism for transgression. The central tension throughout is whether purification removes an external contagion, transforms an inner moral condition, or effectuates an ontological reorientation of the soul toward its divine source.
Purification rituals are therefore involved in all intercourse with the sacred and in all forms of initiation; but they are also employed in crisis situations of madness, illness, and guilt.
Burkert establishes purification rituals as structurally fundamental to Greek sacred life, linking them to initiation, communal boundary-maintenance, and therapeutic response to crisis.

The Orphics thought that life on earth was an expiation for crimes or impurities of previous lives. They were dedicated to the idea of katharsis, 'purification' of their souls.
Edinger identifies katharsis as the central Orphic-Pythagorean soteriological imperative, linking ritual purification to philosophical asceticism and the eschatology of reincarnation.

It is a matter of keeping the daimon within us free from the pollutions that bind it fast to the earthly life. To this end the methods of religious purification are most efficacious.
Rohde presents Empedoclean purification as an internalized daimonic practice aimed at freeing the soul-substance from earthly pollution through asceticism and religious rite.

Through rituals of purification, the sin, evil, or uncleanliness associated with religious violations are removed, and the individual is reconciled to God.
Pargament frames purification cross-culturally as a universal coping mechanism that restores the individual's relationship with the sacred following transgression.

Firstly, purification can refer simply to the purification of non-virtuous habits or dissonant mental states, etc., in which the objects of purification are, without qualification, totally eradicated from one's mental continuum.
Coleman distinguishes two Buddhist meanings of purification — total eradication of non-virtue and the transformation of impure perception — demonstrating the term's semantic range in Tibetan contemplative psychology.

Ficino typically relates purification to the psychological process of becoming celestial: 'A person becomes celestial when he is purged of impurities, completely cleansed of those things which are in him but are different from the heavens.'
Moore via Ficino positions purification as an alchemical-psychological ascent, the removal of sublunary debris enabling the soul's alignment with celestial archetypal motion.

Solutio, again like baptism, also involves a cleansing, a purification, a washing away of debris, allowing a clearer perception of essentials.
Moore links the alchemical solutio to baptismal purification, reading both as processes that dissolve encrusted psychological debris and restore clarity of essential perception.

This is the purification through madness, the purification through music, which was later to play such a prominent role in the discussions about the cathartic effect of tragedy.
Burkert traces the idea of purification-through-affect from Korybantic ritual possession to the cathartic theory of tragedy, establishing the continuity between religious and aesthetic purification.

Where human blood has been shed and requires 'purification' the Kathartic priest accomplishes this 'by driving out murder with murder', i.e. he lets the blood of a sacrificed animal fall over the hands of the polluted person.
Rohde details the mechanics of blood-purification in Greek kathartic practice, where sacrificial substitution neutralizes homicidal pollution through a logic of ritual counter-contamination.

Von Franz reads the Aurora Consurgens' purification imagery as the gathering of scattered soul-particles into the unitary, unstained self, simultaneously chemical, moral, and theological in register.

This change ideally is from impure to pure, if psyche moves upward through creatures. If, during some incarnation, psyche becomes worse, it may face reincarnation in a lower form.

The famous claim that the function of tragedy is 'through pity and fear to accomplish the katharsis of experiences of that kind' does not appear to pick up on anything that has gone before... if we interpret katharsis in either of the two most common ways, as either moral purification or medical purgation.
Nussbaum problematizes the dual interpretation of Aristotelian katharsis — moral purification versus medical purgation — arguing that both standard readings fail to satisfy the definitional requirements of the Poetics.

It would be a valuable experiment to take the highly elaborated kathartic ritual of the Avesta and compare it with the history and technique of purification and expiation in Greek religion.
Rohde advocates a comparative cross-cultural study of purification ritual, noting the continuity from Greek kathartic practice through Zoroastrian and Christian traditions.

A bath followed by dressing in new robes forms part of individual initiations, of initiations into mysteries, and of the wedding ceremony which, of course, is celebrated as a sacrificial feast.
Burkert shows how bathing-as-purification structures key threshold rites — mystery initiations, weddings, priestly preparations — demonstrating purification's role as a liminal technology.

If, according to this conception, contact and pollution are more than merely material, their operation affects the whole man and not only imperils his physical nature but may also burden and corrupt his mental state.
Otto argues that ancient purification logic is neither crudely materialist nor purely spiritual, but operates on a psychosomatic continuum in which corporeal and mental corruption are inseparable.
