Non-physical, immortal, creator.
I have discovered this empirically, but also find it implied by Gen.1:26.
That is the true self within who I am striving to awaken. But then there is the mortal, physical body self housing my consciousness.
And then there is the vulnerable, pervasive and sinister ego standing in the way of my quest.
All of these are "me." And I'm at war, trying to kill one of me so that another of me may awaken. So far, I'm not worthy of that awakening.
