I believe there is a fundamental underlying unity to the universe. I also believe that death of the human body does not equal death of consciousness. I believe there is an "afterlife" of some sort. I further believe that our "adjustment" from human consciousness to the universal consciousness which comes after death is colored by the manner in which we have lived our human lives. A human consciousness which is in reasonable accord with universal consciousness will be easily absorbed into the universal. That's Heaven. A human consciousness which is far out of accord with universal consciousness will both reject and be rejected by the universal. That's Hell. It's the difference between diving into a cool lake and driving into a brick wall.
