To be honest, the nature of the afterlife is a complete mystery to me. It seems to be part of our human nature that we can only speculate on the afterlife during this life.
I do, however, have a faint vision of what the afterlife might be like. I believe that angels and other spiritual beings do exist. I also believe there is a place we might call heaven, where there is peace and happiness in abundance.
Could it perhaps be the case that the afterlife is a kind of mirror image of our Earthly lives, in many respects, and yet without much (or maybe even any) suffering?
It is also possible that a kind of hell exists. Heaven and hell have been spoken about in philosophy for thousands of years. So we should never be so arrogant as to assume we are definitely going to heaven. I can honestly say that the idea of hell terrifies me; we can hardly imagine the horrors that are possible.
This whole discussion serves to underline the spiritual aspect of our existence, and how our human lives are just a fleeting moment in eternity.
