Logic and reason reject the possibility of the existence of a "spiritual" world.As any educated person (especially in the matters of the brain functions) knows,that the conciousness mainly the self-awareness part of it, is produced by the brain. Self-awareness being described as the exact awareness of the existence of ones self; being aware of ones self at any chosen time of the subject, and being able to produce the awareness in an instant.Or by the decomposion of the brain after the demise of the physical body,any function of the brain dies along with it.Knowing this it would not be possible to be aware of ones self in a so called dimension that does not include any material aspect,(the brain in this particular case)because "The spiritual" as defined by the believers is some sort of dimension that is opossed to the physical world,and does not include the laws of physics nor the most basic natural laws such as space,time,matter,gravity.Even if it would be possible to achieve such futile nonsense, once on the otherside, the first human impulse is the self-positioning of ones self.The first question that rises inside ones head after wakeing up from a deep state of unconciousness is "Where Am I".Ofcourse such question would be nonsense in a world that contains no space; not to mention that an individual needs at least one milisecond to become aware and to ask himself that first positioning question.This would ofcourse require time.But According to the believers this feature is also missing from the "spiritual" world.So as you can see all this is logical and rational scientific thinking that no believer bothers to do for himself.One more proof that reason destroys blind and foolish faith.
