Self expression in the depth-psychology corpus is not treated as a simple psychological act of disclosure but as a problem touching the deepest strata of being, creativity, and ontology. Aurobindo frames it cosmologically: the manifold self-expression of the Spirit is the ‘high sense’ of terrestrial existence, so that a perfect self-expression of the spirit is nothing less than the object of human life on earth. This theological register stands at one extreme. At another, Fogel and the embodied self-awareness tradition locate self expression in the body’s voice — the capacity to put embodied feeling into language consonant with one’s True Self — and identify its suppression with neuromotor containment of urges. McNiff, working from art therapy, treats self expression developmentally: even imitation carries a personal style from the outset, revealing intelligences that formal institutions have failed to recognize. Arroyo’s astrological framework renders self expression as the combinatory output of planetary signs and houses, a structured ‘urge toward self-expression’ that is cosmically prescribed for each individual. Greene, from a Jungian-astrological angle, ties spontaneous self expression to the solar principle — the fusion of life and art. Tensions emerge between self expression as cosmic mandate, as embodied authenticity, as creative individuation, and as a drive that must be balanced against self-transcendence (Yalom). The term thus sits at the crossroads of cosmology, depth psychology, somatic theory, and creative arts practice.
