Excerpt from "The Hero With a Thousand Faces" by Joseph Campbell

"Willed introversion, in fact, is one of the classic implements of creative genius and can be employed as a deliberate device. It drives the psychic energies into depth and activates the lost continent of unconscious infantile and archetypal images. The result, of course, may be a disintegration of consciousness more or less complete (neurosis, psychosis: the plight of spellbound Daphne); but on the other hand, if the personality is able to absorb and integrate the new forces, there will be experienced an almost super-human degree of self-consciousness and masterful control. [...] It cannot be described, quite, as an answer to any specific call. Rather, it is a deliberate, terrific refusal to respond to anything but the deepest, highest, richest answer to the as-yet-unknown demand of some waiting void within: a kind of total strike, or rejection of the offered terms of life, as a result of which some power of transformation carries the problem to a plane of new magnitudes, where it is suddenly and finally resolved."
