Bottom line, if this is an accurate and balanced view of the coma experience, we must avoid comas. There is here too much attention paid to brain function, and not enough to psychological meanings. This is best seen in the perfunctory treatment of the OBE experience during the coma. This is the doorway to positive occurrences that is completely ignored by the authors, as if they must not allow any positive aspect to the coma experience, most especially one that skates well outside the primitive neurological, materialistic approach toward profound human experience. Numerous OBE and NDE accounts leave no doubt that mind is not a function of brain, but only uses the brain for expression.
