If one goes deepe enough into their own consciousness they will see or experience the astral heaven or hell. It's all within ourselves. Some can experience through meditations and some through NDE's. The other solution is through physical death but there is no one to tell or authenticate your experience then because the very souls residing in those regions with you.

One thing though that both astral hell and heaven realms are temporary and once a soul finishes there time there they are then reincarted into a life form here on earth and a human form if they are LUCKY. Evil doers (Hitlers, Escobars, etc) usually start at lower forms before getting the human form again.

But again it's a matter of seeing, experiencing, or remembering, not from religious ideologies that say heaven and hell is eternal, not the slighest eternal. However, 1-4 thousand astral years in astral hell will seem like forever and vis versa.
