Explanation:

The awareness is the work and the entity is the inert energy produced by the oxidation of food. The nervous system is the instrument. From the above analysis, the awareness exists, but being un-noticed, it is of secondary importance and does not have the primary importance of an entity. Awareness as work is quite different from the inert energy as well as the nervous system. It is an invisible form of inert energy due to proportionate conversion and it certainly has existence.
