Esoteric Truths
This book provides a wonderful overview of the aim, essence, and application of the ancient Egyptian Mystery teachings.
I have studied in a Gurdjieff school for ten years and another ten years in a school with a direct lineage to the ancient Egyptian Mystery schools. In my opinion, this book is completely "on the money" as far as accuracy and Truth, which could not be possible unless the author had personally partaken in such an esoteric school herself.
One needs, however, to acquaint oneself with the terminologies, which differ from many other terminologies that are out there in the New Age marketplace, not taking any terminology for granted or in the way they might automatically take them.
On the whole, the book provides in a clear and concise way both Knowledge and the practical steps toward digesting this Knowledge, the latter of which being absolutely necessary to the former.
