Enlightenment means direct knowledge of the Seer as Seer. In NDE (Near Death Experience), since there is an experience without body and this experience appears much more real than the experience that a normal mind has, there is a clear realisation that one is not the body and not the mind. One is inclined to call oneself as the individual soul after NDE. There is a feeling of unconditional love, of timelessness etc. in NDE but it is a feeling after all. Seer merely sees without feeling. Seer does not have any individuality also. Negating body and mind is fine but if individual soul is not negated it is not enlightenment. Seer is pure Consciousness which is beyond body, mind and individual soul. NDE does not necessarily mean enlightenment. If Self Inquiry continues during NDE, it can give rise to enlightenment.
