You are not an individual. We are all one and what you consider as your soul is really your ego. There is no death. When you die you go back into oneness. Heaven and hell are a state of mind. Re-incarnation is just the universe imitating itself. There is no meaning to existence that a human mind can comprehend. The only way for man to answer the guestion to everything is to evolve. Next step of evolution is spiritual, not physical. That's where man becomes god. If man does not evolve according to universe, man will be cut off like a spreading tumor.
