The faint echo of the Fire Music—the Loki motif—is not out of key, for what does ‘fulness of life’ mean? What does ‘wholeness’ mean? I feel that there is every reason here for some anxiety, since man as a whole being casts a shadow.
Jung invokes the Loki motif as the disquieting fire-shadow that necessarily accompanies any genuine claim to psychic wholeness, warning that integration cannot be achieved without confronting this dark, incendiary counterpart.
