Is there a Heaven or Hell?

[Infinity]

.To my understanding when we die, we first go to the astral realm, the lower realms are supposed to be "hell-like", while the higher are supposed to be "heaven-like", and so on in to the 5th. There is an idea around that heaven and hell are side by side so that fits with this.

I'm just curious, where did you receive the information you know about Heaven and Hell? And under what circumstances does one go to either Heaven or Hell?

Infinity, these things are mentioned in William Buhlmans or Robert Monroes books about Out of body travel... it works with "like attracts like" - depending on how your vibration is, you either go to the lower astral places, that can seem like hell, as the Eternal said, or to the higher places.
Since astral projection is similar to physical death (you leave your physical vehicle for a while) for me this presents tangible evidence.
I recommend these two authors for anyone who is interested in OBEs.
there is also a good book by C.W. Leadbeater, called "the astral plane".

Then when is the time that we re-incarnate after we die?
