Are you the same person you were seven years ago? How about last year? Yesterday?
I don’t know about you, but I’m not even the same person I was seven minutes ago! One way to view classical thought on reincarnation is archetypical – instead of your physical body passing away and you being reborn with the body of a fox or a celestial being, look at the process as your mind/attitude transforming into that of a different entity. Sometimes we’re the archetype of the celestial being, sometimes we’re the avenging demon, sometimes wily as the fox, sometimes peaceful as the lamb.
Watch as you transform moment by moment. How do your actions affect your next “incarnation”? What are you incarnated as right now?
