What does it mean to be "conscious" in the physical plane? Does it simply mean to be alive or does it mean to also be aware? And, what are we aware of? Of the myriad perceptions, to which do we choose to consciously attend?
Our physical life is not just what we hold in our daily conscious mind, it is also the ability to be "conscious" of what we try to hide deep inside ourselves. Often, we hide memories in our unconscious mind, and some of our hidden life is stored in our superconscious mind. To be truly "conscious" in our mundane life we must also be aware of these other, hidden, portions of our total consciousness. Otherwise, we will not have access to all of our choices of perception.
