When I first realized I was not a body
It wasn't a complete awakening as such, I didn't suddenly relinquish every single way in which I think of others and myself as bodies, but just the idea of it was given birth, perhaps marking the beginning of a spiritual adventure in self exploration. It was like a first step through a doorway into a whole new way of relating to myself.
Jesus knew fully that he was not a body. He was capable of manifesting and dematerializing his body, and in fact was capable of re-manifesting different bodies depending on who he was with. That's what becomes possible when you are completely free of all confusion about what you are - that you or others are not a body at all. That's what it means to have mastery over it and freedom from it. It no longer limits you or defines your identity.
