The anima, a Jungian concept, is a personification of all feminine psychological tendencies in a man’s psyche and may manifest as vague feelings or moods, prophetic hunches, capacity for personal love, feeling for nature and is directly connected to his relationship to the unconscious.
The character of a man’s anima is shaped by his mother. If he feels his relationship with his mother was primarily negative, or that his mother had a negative influence on him, this will manifest in the man’s temperament as irritable, depressed moods, uncertainty, insecurity and touchiness.
If, however, he has been able to overcome the negative assaults on himself and the negative-mother anima figure has been resolved, this can even serve to reinforce a man’s masculinity, drawing on his masculine traits to perpetuate his existential quandary. For such a man, issues central to his existence revolve on an endless loop of internal dialogue following this theme:
“I am nothing. Nothing makes any sense. In others, it’s different but, for me, I enjoy nothing.”
For such a man, the whole of life takes on a sad and depressive mood.
In such cases where a man feels his mother has been a positive influence, he either becomes effeminate or is preyed upon by women or he may become overly sentimental or as touchy as an “old maid”.
As a very basic primer to the Jungian concepts of anima and animus, I have summarized a few key points from the linked video. However, if you want to know more, you ought to watch the video, as it explains the concept better than I am able.
