Nirvana is what people experience when chemicals in their brains are released when they are near to death. This is simulated with DMT. The real experience to the other side is VERY different but can be accessed through knowing Jesus/The Christian God. It is an extremely bright place, made of consciousness (I think, I was only there for a short time) and is beautiful and peaceful most of all. Everything there is hyper-real compared to this existence we are living in now, and this world will look dark and blurry in comparison when you come back. Talk to Jesus, man. Time is short.
