Jumping the gun here. I'll start my night-shifts tomorrow evening and hope to have time to watch the video then.
First of I consider ego to be a non-existent entity. It's a (very rapidly) repeated constructed idea of self which doesn't exist anywhere but in the attachment to the idea itself.
Which is exactly why I have to create a space to incorporate a narcissist.
Karma in my view does span lifetimes, but those or not linked to an idea of self. So it will not be my karma, but just karma. Life spanning Karmic patterns in my view are unresolved intentions. All we do as humans is pick up these intentions and either resolve them (i.e. clear the Karma) or don't which means the intention needs another being to become resolved. The fact that we can connect to the personality that originally intended the karmic pattern/desire has to do with the way intentions are stored in the universe. I have come to believe that an intentional construct holds the space to incorporate all information that went along with the intention, thus holding information about the person that intended the bloody thing in the first place. The way we access that information is from within making it appear as if it's our idea of (non existent)self that intended it in another lifetime.
With Love
