Individuals often do not know their own mind. Most thinking is automatic and frequently unchecked. During waking hours, the separation between mind and consciousness is not often discernible. The character of consciousness makes the mind both simple and complex at the same time. Simple in that if a person has awareness, they are in charge of what they are thinking, feeling, and doing. Complex in that seeming awareness is often compromised, clouded by an unconscious (subconscious) mind.
