Many myths and fairy tales tell of a prince, who has been turned into an animal or a monster by sorcery, being saved by a woman. This is a symbolic representation of the development of the animus toward consciousness. Often the heroine may ask no questions of her mysterious lover, or she is only allowed to meet him in darkness. She is to save him through her blind faith and love, but this never works. She always breaks her promise and is only able to find her beloved again after a long quest.

As the anima does with men, the animus also creates states of possession in women. In myths and fairy tales this condition is often represented by the devil or an "old man of the mountain," that is, a troll or ogre, holding the heroine prisoner and forcing her to kill all men who approach her or to deliver them into the hands of the demon; or else the father shuts up the heroine in a tower or a grave or sets her on a glass mountain, so that no one can get near her. In such cases, the heroine can often do nothing but wait patiently for a savior to deliver her from her plight. Through her suffering, the animus (for both the demon and the savior are two aspects of the same inner power) can be gradually transformed into a positive inner force.
