It is not necessary to prove our present life on the anvil of logic and proof for it is obvious and something we are able to experience and therefore proven. Past life is not visible, not available for easy experience and therefore one requires it to be proven with convincing evidence.
Rebirth has been explained in Jain, Buddhist and the Upanishadic texts since centuries now. In the past couple of centuries, scientific evidence has assumed great importance. Some psychologists have worked on the subject of rebirth with scientific tools.
In this book, Muni Kishanlal has brought together the wisdom of ancient texts, the discoveries of psychologists and the results of meditation camps which explored the possibility or recollecting past lives. I am sure this book will help to understand better, the idea of rebirth.
