The purpose of this book is therefore to help towards the understanding of these processes which are essential to life if that life is not to remain static. The theories involved are both old and new. Those that are not new have been found in the general literature of mysticism, religion and philosophy and no attempt has been made to identify the sources. The attempt has been rather to integrate them into some unified structure and to re-express them in another form. Not only will there be an attempt to map out the geography of the psyche and consciousness in general but also to describe the principles which are necessary for a journey and the best way to understand the ‘Gods’ and ‘Devils’ that we may meet on the way.
