If we knew we were living all of our lifetimes at once, every step could feel like hiking up a sand dune wearing a car.
I practice the multi-verse game on a daily basis. In any moment there are Infinite moments. Some look almost identical to each other with only slight variations. Hard to detect unless you're really paying attention. Other parallels are obvious.
How does it feel to hop onto a parallel timeline and perhaps back again? We all know because we do it constantly, refining our experience through a deeply embedded internal satnav (GPS) programmed with our preference parameters.
The weirdest thing about this life, and weird isn't bad you understand, is that we can be aware that we're living many lifetimes at once. It's like multi-dimensional wizard's chess.
My mystery school Teacher once joked that "God put on a video...and it's you." Now, he didn't believe in an all-powerful external authority with whiskers and the ultimate veto-vote, and maybe you do... that's not the point.
The point is that this is a lifetme where we have infinite choices in every moment. And life gets more interesting the more we exercise those choices.
If the stars are the runway lights of reality, there must be infinite places to land. Why not visit a few?
