This book is a great introduction to the techniques of creative visualization. It is set out in a workbook format, though the majority of the practical exercises are given in the last chapters. The author does repeat himself, though he does give a valid reason for so doing.
I would recommend starting the exercises in the earlier chapter as soon as you read it. If you have an aversion to ceremonial magic, you may find the exercises a little annoying, but, for the purposes of progressing, work through the practice visualizations as given. This is only a starting point and the author gives symbols which are quite easy to start with, regardless of their purpose.
I can highly recommend this book to anyone wishing to undertake basic work in the occult arts. The author helps to de-mystify what is an awkward, esoteric subject to teach.
