In case after case, One Soul, Many Lives engages the reader with the remarkable story of someone who believes he has lived before. In addition to testimony by reputable and trustworthy individuals, One Soul, Many Lives draws heavily on the work of eminent scientists to authenticate its compelling stories.

The evidence supporting the stories includes a young boy with scars on his head that precisely match the autopsy of the murdered man he believes he was in a former life; individuals whose illnesses and phobias can be traced back to a past life and healed; and people who can speak a foreign language fluently during regression.
