"The Occult of Today Is the Science of Tomorrow." I have chosen this motto for my book relating to the occult, for it is an attempt to describe the (at first) very small experiences and knowledge which led me to see the reality of the true occult world lying like an almost uncharted country behind the thick jungle of fraud and charlatanry, and which have led me also to state in comparative detail what I found on my journey and the conclusions it compelled. I use the illustration of "going through the Looking Glass" for two excellent reasons. Firstly, everyone knows that remarkable story of Alice, dear to two or three generations, and how she passed through the Looking Glass to the queer upside-down sort of country behind it. Secondly, few people realize that the book is a wonderful parable of how you can get through the mere reflections of things into the reality behind them if only you know the way. Carroll, who was a great mathematician, knew of the undiscovered country from that point of view. I found a very different road and as a matter of fact there are almost as many roads as there are people. The country behind the Looking Glass, generally called the Occult world, is reality, and the daily world we live in is Shadow-land though the reflections look so hard and bright and real that they take most of us in.
