The Anima is the personification of all feminine psychological tendencies within a man, the archetypal feminine symbolism within a man's unconscious. The Animus is the personification of all masculine psychological tendencies within a woman, the archetypal masculine symbolism within a woman's unconscious. In dreams Jung said that the animus is more likely to be personified by multiple male figures, while the anima is frequently a single female. One might look on the concept of anima-animus as a kind of yin/yang solution to the duality of human sexuality. They are products of the long human experience of man with woman and woman with man: as man has opened to his feminine nature, so has woman a corresponding male side. They also act as collective images which motivate each sex to respond to and understand members of the other gender. That is, a man apprehends the nature of woman by virtue of his hidden anima, – and reciprocating, the woman is able to grasp the nature of maleness via her animus.
