In a public situation, we present a different version of ourselves than from the one at home. Every profession has unspoken agreements about which manners are acceptable, and which are not.

It is then the purpose of the persona to suppress the impulses and emotions that are not considered socially acceptable. The difficulty is when one becomes so identified with his persona that he loses all sense of self. The result is an inflated persona with excessive concern for what people think and a lack of courage to endure conflict and refuse others' wishes.

The 'shadow self' is everything a person has denied in themselves, such as spontaneity, aggression, cowardice, carelessness, passion, enthusiasm. It embraces all the thoughts and moods for which we feel guilt and shame.

The shadow is emotional, for it must oppose the rigidness of the ego. It is prone to psychological projection, where we attribute to others the inferior qualities we do not want to admit are in ourselves. When we perceive a moral deficiency in others, we can be sure there is similar inferiority within ourselves.
