Dua NTR for this information from the Book Metu Neter by Ra Un Nefer Amen
Today I will feed you Amen
Amen means "concealed". It corresponds to the essential nature of the Supreme Being, which is the same as the essence of Man's being. It is our unmanifested,unmanifestable unconditioned Self-That which is the ultimate source of life and consciousness. It is the unseen and seeable that looks out into the Objective Realm of spirits,thoughts,feelings,and physical phenomena. We must return our focus of conciousness back to it by the cessation of all thought activity. Once we have established this innermost point as our place of being,i.e. living beyond emotional influences--we will attain the state of Hetep. This is a state in which we are able to fully ignore all emotions that rise into our awareness,and thus attain to a peace that cannot be disturbed by any challenge in life. This state of inner peace is the prime foundation for the functioning of the healing functions of life force (Ra),and all of its spiritual power.
