Heaviness in the depth-psychology corpus occupies a surprisingly rich semantic field, ranging across physical, cosmological, psychological, and somatic registers. Plato’s Timaeus supplies the foundational cosmological account, where heaviness is not a function of spatial orientation (above/below) but of the difficulty of separating an element from its like — a principle later echoed in Stoic and Epicurean physics. Within depth psychology proper, however, heaviness migrates inward: James Hollis reads it as the phenomenological signature of endogenous depression, a constitutional burden that sufferers carry as if perpetually ascending a gradient others traverse on level ground. The I Ching commentary of Ritsema and Karcher identifies heaviness (NAN) as the necessary accompaniment of turning-away, the limping ardor required when forward movement is obstructed. Hillman’s Saturnine meditations connect heaviness to melancholy, the chthonic pull toward the imum coeli and a hidden interior earth. In somatic and body-oriented traditions — Price’s MABT work, Ogden’s sensorimotor approach — heaviness appears as an interoceptive datum, a felt sense located in specific body regions that, when attended to with sustained mindfulness, becomes a threshold to deeper psychic material. Hillman also deploys elephantine heaviness as an archetypal image of psychic blockage that paradoxically serves as a supporting base. The corpus thus charts heaviness across four axes: cosmological weight, depressive burden, limping resistance to change, and somatic signal.
