This book publishes the initiation rituals for the Aurum Solis and discusses briefly their context as magical tools. For students of Western mystery traditions, it worth study. These rituals are far more Greek-oriented than most other Western occult material.
While the work shows some similarity to some Freemasonic material, the similarity is more mild than what one sees in direct offshoots such as the Golden Dawn etc.
All in all, I think this is a useful contribution to the field of study in this topic and would recommend the work
