The only thing that can be known to be real is Consciousness. They call it the substance out of which EVERYTHING is made.
The universe is infinite.
The entire universe is consciousness, you are consciousness.
So, consciousness is infinite, no limits whatsoever. There are now laws, consciousness can do anything.
(These are things you can become directly conscious/aware of)
Now I’m gonna explain it the way I read it in a book (and I hope I’m remembering correctly)
Let’s say consciousness is the screen on which the movie (your life) is being played or “lived”
So, consciousness (the screen) can play anything it wants (just like any movie) and the movie/your life is whatever you believe is true
That’s precisely what’s happening with those people, they believe hell and heaven, or karma are real so consciousness takes on the form of heaven, hell, and karma and then it’s real to them. They are not Truth because those are distinctions, which the human mind makes, such as Good vs Bad. The human mind can only come up with relatives truth, good is relative, bad is relative, heaven and hell is relative, karma is relative. It’s all relative for whomever imagines it to be true.
Absolute Truth operates in a non-dual domain. Absolute Truth is that Everything is One, you cannot compare it with/to something else.
Absolute Truth is Consciousness :D
