Dr. Eben Alexander was hooked up to clusters of tubes and medical instruments that monitored every bodily function and and non-function during his NDE. His body was diligently mapping the story while the mind and consciousness were engaged elsewhere. 

Shortly after I interviewed him on 'Proof of Heaven' (Conscious Living/Empower Radio 2012), he appeared on Oprah and took some major heat from a writer who tried, unsuccessfully, to discredit him. 

Still enthusiastic and driven to share the details and encourage any who have doubt about an afterlife to be open to exploring their own knowing and, if possible, expand that knowing through meditation.
