Time and time again i have travelled down this path.
It is a book about past life recalls. I ask to be shown about a past life before I go to sleep and, if it is appropriate, I am shown one. It's an interesting experience Sometimes I am shown a world I have no fore knowledge of and at other times i am shown a world where I seem to have deep memory of. The Court of King Henry V111 of England is a time of viviid recall.The memory surrounding the Dauphin of France is one I recoil from as I did not have fond memories of the time and place.
Usually I am reminded of a lesson I had to learn and on occasions I have to repeat the lesson if I have not learned the lesson, although that is only my recall.
I consider myself fortunate to have learned these lessons. It's something not everyone is shown.
