I don't believe that consciousness is generated by the brain. I believe that the brain is more of a reciever of consciousness. - Graham Hancock

We might feel very sure that there is no more to reality that the material world in which we live, but we cannot prove that this is the case. Theoretically there could be other realms, other dimensions, as all religious traditions and quantum physics alike maintain. Theoretically, the brain could be as much a receiver as a generator of consciousness and thus might be fine-tuned in altered states to pick up wavelengths that are normally not accessible to us.
