This manual contains twelve lessons, one for each number, beginning with number one, (lesson twelve discusses numbers twelve and thirteen). These lessons are not intended for casual reading, but for careful study and meditation, wherein it is hoped that by a lifting and acceleration of consciousness, the student may be able to contact more fully the inner man - that source of wisdom and light eternal which makes life complete both within and without.
This is a good insight into the science of numbers, their connection to spirituality and your higher self. You will be looking at numbers differently after you have read this book. I think you might benefit from having an understanding of one of the main religuous teachings, which I don't have, but nevertheless I found it fascinating
