We live most of our life through three states of consciousness: waking, dreaming and sleeping.
In the waking state of consciousness, we experience the world through the five senses. We seek elevation and joy from these senses. If any one of the senses is missing, the entire dimension of that sense is lost. One who cannot hear is bereft of the whole arena of sound. Similarly, he who cannot see is deprived of all the beautiful sights and colors. So, the sense is more important and much bigger than the object of the sense.
