To repeat what I've said before, this "deep level" I refer to is easily understood in the following way. You are in a plane plunging towards earth and feel you're going to die. Do you concentrate on your rebirth at that time...what type, where, etc. or...do you react purely in an existential manner...clinging to this very life, because you don't feel there's any life or consciousness or continuity for you other than right here, right now. There are many people who may speak of rebirth as if it exists who will quickly reject it (due to grave doubt) when plunging to earth in that plane. I know, I'm one of them (just some bad turbulence, in my case, was all it took!).
