When you are alive , you are conscious .It is consciousness that defines your aliveness. The other way,it is aliveness that causes consciousness. When I experience something my consciousness is temporarily suspended in order to register sensations and record experiences .I have been thinking of why ,when I am typing this ,I am not simultaneously conscious of my typing. I have often found that I may have been subconsciously aware of the experiences I am going through but not all the time. For example I do a hundred things during the day but find it difficult to remember all the experiences when I try to recall them later. I have found over the years it is expedient to let another part of mind to offer a running commentary on what is taking place. There is a continuous drone in the back of my mind which is a kind of a background commentary offered by another part of my mind which makes me conscious. The sound inside is a persistent commentary which tries to synthesize my experiences and make some sense out of them before they are filed away.
