Across the depth-psychology corpus, ‘sky’ functions as one of the most semantically saturated cosmological symbols, operating simultaneously as hierophany, psychological metaphor, and cosmogonic principle. Eliade anchors the dominant tradition: the sky ‘directly, naturally, reveals the infinite distance, the transcendence of the deity,’ making it the privileged epiphany of supreme beings and the axis of vertical sacred experience. This celestial transcendence is not merely theological but structurally psychological — the sky discloses the modality of being itself. A second major current, running from Corbin through Iranian Sufi sources, internalizes the sky: the ‘Skies of the heart’ (asman-e del) become the subtle astral body of the soul, transforming cosmological space into visionary interiority. Von Franz and the Jungian mythographic tradition read sky-earth separation as the primordial cosmogonic act, the differentiation of lighter from heavier, spirit from matter. Bly interrogates the gendering of this axis — sky-father/earth-mother — uncovering suppressed countertypes such as sky-mother (Nut) and earth-father (Geb). In contemporary clinical application, ACT therapy appropriates the sky-and-weather metaphor, derived explicitly from Hinduism, Buddhism, and Taoism, to render the observing self as the unchanging expanse behind transient affective weather. The tension between sky as transcendent otherness and sky as internalized depth — outer cosmos versus inner heaven — constitutes the field’s central dialectic around this term.
