​You are what you believe.  If you believe that you are body and mind, you will always feel incomplete, because at any one time you can only ever be one half of a duality.  This creates a lack, a need, and makes you look for fulfillment in the external world of objects rather than in the subject, in "I AM", in your inner world, which alone is real.  

When you live with the conviction that “I AM” is real, the external world ceases to impress you and you are no longer defined by it. What then arises is the “I” whose nature is absolute Bliss.

That "I" is pure Consciousness. It is given the name Awareness, the Self or God.  That is the real "I". That "I" is the same in all. 

You are not finite and mortal, you are Infinite and Eternal. ​You are not here to believe in a God that is separate from you, but to believe in your nobility of being one with Him.​
