According to Osho, unawareness is identification with the mind—mistaking thoughts, emotions, and moods for who you are. When anger, greed, or hate arises and you become it, you are unconscious. Awareness begins by recognizing the mind as a temporary mechanism and remaining a detached witness, remembering, 'This too will pass.'
Unawareness is when you think you are your thoughts and feelings instead of just watching them come and go.
