If you could lay your past lifetime out in a long timeline, then select any spot using your memory, or sticking a pin into any random part of the life-line, you would come to a period in your life and a certain place where you were living or visiting. This could be worked out mathematically and precisely to enable a return visit to the most beautiful place you have ever been to in your life. A place where you reached the highest level of happy peaceful contentment where a return visit would recapture the feelings of exquisite intellectual pleasure regained.
