Book excerpt: Do you have a soul? If you do, is it mortal, immortal, or eternal? If you don't know the difference, how can you expect to go to heaven? Are there people without souls? That would explain a lot, wouldn't it? Believe it or not, but the whole of reality can be understood through a proper understanding of eternity, immortality and temporality (mortality). These three terms are inextricably entwined with the concept of soul/mind. There are three possibilities: 1) One eternal mind (God) creates everything else, including immortal souls. This is the Abrahamic position. 2) Everything in the universe is made of individual eternal minds, or of one eternal Mind. This is the position of much of Eastern religion, and also of the Western esoteric tradition. 3) There are no minds at all, whether eternal or immortal, and all that exists is temporal matter, from which temporal minds are inexplicably made, and which perish when their bodies perish. This is the position of atheism and scientism. What kind of soul do you have?
