Many humans, especially in technological countries are atheists. They believe that there is no spirit world, no souls, no god, but only the physical world, physical body and physical mind. They believe that there is no higher intelligence and all random events just happen at random. They usually believe that humans are the only intelligent life form in the universe and that we and all life evolved as a result of random events and unintelligent laws of nature.
Although this atheistic and materialistic system of beliefs may sound crazy to you, it is a popular system in a technological society and it provides souls with a unique and energizing experience. This experience is focused on survival. Imagine feeling isolated and unaware of anything nonmaterial. Everything that happens to you is a result of your physical actions. Somehow this isolation makes human individuals feel each like a God. Each feels alone in a hostile world. Their life becomes a fight for control, resources and pleasures.
Sometimes even those humans develop into kind, compassionate and spiritual humans although they still would consider themselves atheists. How is it possible? Mostly this is due to a fragmentation of the mind and lack of coherence within.
