spirits origin is outside of space-time.
spirit enters space-time in specific pattern.
first as math and physics, then as chemistry and matter, then biology, then mind then spirit then god.
when it completes this cycle it goes back and starts again enriching the whole cycle.
we as humans in our ordinary self embody only a small part of creation, but in our higher self we embody the whole.
when our ordinary self dies, and our spirit goes back to where it came and we see our true self, which has lived as every self.
the end of time is when you die,
the last judgement is your last judgement.
like Shakespeare said, the world is a theatre and there is only one actor, playing every role in the great story. we are born and put on the costume (body) of a certain character, and we can choose the role we play to a degree; but we are so caught up in our ideas of who we should be we forget that this is all a big game for spirits entertainment and education
