The 'I am' is the essence of the five elements and three
qualities that make up the body and mind and all these are unreal.
Why are they unreal? Because they are interdependent, constantly
changing and the real is not dependent and never changes. This
essential knowledge 'I am' has become a root habit with you and
misled you into believing that you are a person with a body born in
this world who will die one day. This root habit has got so deeply
ingrained into you that it is very difficult to disbelieve it.
