The Triple-Headed Eagle vs The Traveler
“Psychologically, the three-headed bird could represent a situation where the intellect feels ungrounded, dissociated, and thrown into an immobilizing state of confusion. Things that used to make sense just don't.”
"At this point, a person may fall into utter despair, regress back to intellectualization or frantic activity, decide to join in the spoils ('Living well is the best revenge'), or trying to renounce the world and lead an ascetic life."
"The analyst, as well as the patient, must bear this new darkness and not try to move out of it with suggestions or impatient withdrawal of interest."
The Traveler expresses a conflict of will in the face of change.The house or conscious ego, wants to keep moving ahead while the dog is literally "driven" by compulsion. There is a strong conflict between the instinctive and spiritual, conscious and unconscious, pushing in different directions similarly to the armored knights (conscious) and the peasants (Nature, or the unconscious) in the alchemical plate.
