The World Mountain stands among the most richly attested symbols in the depth-psychology and comparative-religion corpus, functioning simultaneously as cosmological axis, sacred center, and psychological image of the self’s vertical aspiration. Eliade provides the foundational phenomenological account: the cosmic mountain marks the center of the world, serves as axis mundi connecting heaven and earth, and is reproduced architecturally in temple, ziggurat, and stupa — each becoming, by symbolic extension, a Sacred Mountain. Campbell elaborates this across multiple civilizations, tracing the World Mountain from Akkadian cylinder seals (the sun-god ascending the primordial peak) to Olmec earthworks in Mesoamerica, treating it as a cross-cultural expression of the desire to situate human existence at the meeting point of cosmic planes. Zimmer grounds the symbol in Indian metaphysics, where Meru — ‘the central peak of the world, the main pin of the universe, the vertical axis’ — organizes the entire Hindu-Buddhist cosmography. Corbin’s Ishraqī reading adds a microcosmic dimension: the vertical axis is simultaneously the inner architecture of the human being, whose subtle centers ascend toward a celestial pole. What distinguishes this symbol in depth-psychological treatment is the convergence between outer cosmic geography and inner psychic structure — the mountain is not merely a place but an orientation, an image of centration.
