If you are looking for scientifically explained phenomenon about spontaneous past life glimpses from leading authors in this field then this is a good one for you. The author brings us 20 first hand case studies with contributions made by Stanislov Graf and Edgar Mitchell to name but a few, which adds validity to the experiences felt by these people.
The book starts by explaining what exactly is an Akashic experience in the authors own words i shall proceed with the answer;
To give a basic definition of an AE unlike giving a scientific explanation of it is not difficult. An AE is a real, lived experience they conveys a thought, an image, or an intuition that was not, and very likely could not have been, transmitted by our senses either at the time it happened, or at anytime beforehand..At least not in our lifetime. In popular, though overused and misused formulation, the AE, is a lived experience in the extra- or non- sensory mode.
It can come in many guises as this book will undoubtedly show, and the fact it has happened to scientists and other such academics adds weight to the argument..
