Ascension: In the fire of the work, or on fire with their work, alchemists are subject to fire’s defiance of gravity, and they imagine their work pointing upward in accord with the flames and the heat they are attempting to control. From lower to higher; from inert to active; heavy to light
Hillman argues that ascension is the primary phenomenological signature of fire in alchemical psychology, grounding the spiritual concept empirically in laboratory observation and linking it to the imagination of upward transformation.
