I'd estimate that I have gotten something between 5 - 30% of this right, and the rest wrong. Which parts exactly, I can't really tell. I don't also think that I'm particularly more out there with my beliefs than humans usually are.
Just for the background info, I'm a theistic mystic influenced by various religions and philosophies. I believe that my 'religion' is unlikely to be the ultimate truth. But I also believe that there is some truth to it.
For me my beliefs are a user interface to experiential spirituality, not so much a consistent religious world view. I might pray to God, because that happens to be the religious language my soul is used to speak, but as for is God, as I understand him, anymore of a god than something else is in the great scheme of things, I'm not so sure about that. Chances are he might not be.
If I am wrong totally, I would expect that I never find it out since I would simply cease to exist after my death. So, if I rejected what I believe now, the next most likely thing would be materialism where there is no afterlife. I'm not particularly scared of having gotten this wrong in a sense that I end up finding out that Islam is the truth for example. Religions don't impress me because they have so visible touch of a man to them. But behind the something that inspired man to invent all the religions, there might be something great.
