” The anima is a factor of the utmost importance in the psychology of a man wherever emotions and affects are at work. She intensifies, exaggerates, falsifies, and mythologizes all emotional relations with his work and with other people of both sexes. The resultant fantasies and entanglements are all her doing. When the anima is strongly constellated, she softens the man’s character and makes him touchy, irritable, moody, jealous, vain, and unadjusted. He is then in a state of “discontent” and spreads discontent all around him. Sometimes the man’s relationship to the woman who has caught his anima accounts for the existence of this syndrome.”
