What is the meaning of the word 'conscious'?

The Word conscious is used in different contexts. We say we are conscious, we say we have become unconscious, and we say the mind works with its subconscious when we sleep. Some people even talk of the Word super conscious which leads to telepathy, intuition, sixth sense and hunches. But the Word conscious comes from the Word consciousness. Consciousness is becoming aware, becoming the witness of the body, the mind and the ego. Consciousness is not believing that we are the one who is alive in the body, the body is just a habitat, we are actually that state of awareness, awakening, that state of consciousness, that is our real existence but unfortunately we are so busy in this world that talks of being conscious and unconscious and subconscious that we have lost the true meaning of consciousness.
