Dr. Eben Alexander on consciousness and the afterlife

Neurosurgeon Dr. Eben Alexander – who suffered a near-death experience that sent him on a journey to find the source of consciousness – says science shows that the brain does not create consciousness, explains why he believes reincarnation and the afterlife exist, and weighs in on whether science and faith are truly at odds with each other. Plus, his co-author Karen Newell joins to discuss the power of sound and meditation over our consciousness.
