Let me start this review by saying: I went into this book while already believing in life after death and the one consciousness. That being said, this book was not it.
(side note: English is not my first language)

It is meant to convince us that our consciousness is eternal and will never die. I.m.o it failed. More than half of the book is research on ways they can prove our consciousness is eternal. They are: Near death experiences, mediums channeling souls, radio contact with the dead and people knowing things about their past lives i.e. via hypnoses or kids remembering certain facts. All these examples (which were dry i.m.o. the 19732 names mentioned in research papers make them highly unclear) ended with: though we can't really, with any real certainty, prove that these experiences were real, we do find the evidence to be sufficient enough to prove it.. Not to mention the fact that religions over centuries and centuries all believe our consciousness does not die when our bodies do is a very big piece of evidence that is only mentioned for maybe 1 pharagraph.

All in all, I still believe, but this book could have done a way beter job at convincing us.
