Ablution occupies a precise and consequential position in the depth-psychological reading of alchemical transformation. Across the corpus, the term designates the washing or purification of the blackened, impure matter following the nigredo—the phase in which contamination, shadow, and corruption must be dissolved and removed before the whitening albedo can emerge. Jung treats ablution in Mysterium Coniunctionis as functionally analogous to baptismal cleansing: the aqua pontica performs for the alchemical lato what sacred water performs for the sinner, a ritual removal of impurity that is simultaneously a psychological event. Abraham's Dictionary of Alchemical Imagery situates ablution squarely between the nigredo and the peacock's tail, emphasizing its role as the operative mechanism by which the blackened body of the Stone is purified through mercurial water. Edinger translates this into clinical idiom: washing imagery in dreams maps onto the psychotherapeutic process of cleansing projection and shadow. Hillman introduces a subtle distinction between ablution as dissolution—the ego-threatening regression into the oceanic—and ablution as nutrition, where transformation proceeds from within rather than by dissolution. The I Ching tradition, via the Kuan hexagram commentary, frames the pre-sacrificial ablution as the moment of maximal sacred presence, the threshold of numinous attention. The term thus gathers around itself the tension between purification as annihilation and purification as preparation for a higher state.

Its chief function is ablution, the cleansing of the sinner, and in alchemy this is the 'lato,' the impure body; hence the oft-repeated saying attributed to Elbo Interfector: 'Whiten the lato and rend the books, lest your hearts be rent asunder.'
Jung identifies ablution as the alchemical equivalent of baptismal cleansing, mapping the purification of the impure body (lato) onto the psychological necessity of confronting and dissolving moral and psychic impurity.

The motto of emblem 3 in the same treatise says of the ablution or washing process: 'Go to the woman who washes the sheets and do as she does'
Abraham defines ablution as one of the two principal operations of purification in the early stages of the opus, linked to domestic washing imagery and positioned alongside cooking as a feminized, transformative labor.
Abraham, Lyndy, A Dictionary of Alchemical Imagery, 1998thesis
After the nigredo, the blackened body of the Stone is washed and purified by the 'mercurial water' during the process of 'ablution. When the blackness of the nigredo is washed away, it is succeeded by the appearance of all the colours of the 'rainbow'
Abraham precisely locates ablution as the operative transition between nigredo and the cauda pavonis, establishing it as the cleansing mechanism that enables the emergence of iridescent coloration and the approach of albedo.
Abraham, Lyndy, A Dictionary of Alchemical Imagery, 1998thesis
as far as the ancestral temple sacrifice is concerned, there is nothing more worth Viewing than the ablution... when the Viewing reaches the ablution, it 'fills one with trust and makes for a solemn attitude.'
The Wang Bi commentary on the I Ching positions the pre-sacrificial ablution as the moment of supreme numinous presence, before which reverential attention is highest and after which ceremony becomes merely procedural.
Wang Bi, Richard John Lynn, The Classic of Changes: A New Translation of the I Ching as Interpreted by Wang Bi, 1994thesis
When ablution is achieved through nutrition (or imbibition) it has another meaning than dissolution. I take the milk into my body rather than its taking my body into itself and dissolving me in the oceanic bliss of the mother.
Hillman distinguishes two modes of ablution—regressive dissolution into the maternal matrix versus active nutritive incorporation—arguing that the latter preserves ego integrity while still enabling interior transformation.
a certain purification of things precedeth the work of perfect preparation, which by some is called cleansing, by some administration, by some rectification, by some ablutio
Von Franz, citing Pseudo-Aristotle, documents the range of alchemical synonyms for ablution, establishing it as a recognized technical operation preceding the magisterium proper.

'What is ablution? It is not merely cleansing the body with holy water, but following the Right and Moral Way' (Tomobe-no-Yasutaka, Shinto-Shoden-Kuju).
Campbell draws on the Shinto doctrinal tradition to demonstrate that ablution's deepest meaning transcends ritual bodily cleansing, pointing toward an ethical and spiritual purification aligned with the numinous Way.

Therefore they shall cleanse me... cleansed from the greatest sin... for from the sole of my foot unto the crown [of my head] there is no soundness (found) in me.
The Aurora Consurgens text, as interpreted by von Franz, situates ablution within a penitential theology of total impurity, wherein complete somatic and spiritual cleansing is the precondition for alchemical and psychic renewal.

If one is psychologically clean, one will not contaminate one's environment with shadow projections... Christ and the sun as partners in baptism... he comes forth strengthened out of the depths, a new sun, and shines his light upon men, having been cleansed in the water.
Edinger maps the alchemical ablution onto the psychological imperative to cleanse shadow projections, linking baptismal water, solar renewal, and the purification of consciousness in a unified symbolic register.

The Mysterium Coniunctionis index records ablution at two distinct loci, confirming the term's recurrence as a significant operative concept within Jung's most comprehensive alchemical study.

The index to Jung's early collected works registers both the Latin ablutio and its English equivalent at distinct page references, indicating early engagement with the term across alchemical and psychological contexts.
