Possesion

The body exists in a world that seems to contain two voices fighting for its possession. 

In this perceived constellation the body is seen as capable of shifting its allegiance from one to the other, making the concepts of both
health and sickness meaningful. 

The ego makes a fundamental confusion between means and end as it always does.

Regarding the body as an end, the ego has no real use for it because it is not an end.

You must have noticed an outstanding characteristic of every end that the ego has accepted as its own. 
When you have achieved it, it has not satisfied you.

This is why the ego is forced to shift ceaselessly from one goal to another, so that you will continue to hope it can yet offer you something.
