For modern astrologers, a complete step by step guide to learning and using traditional western astrology techniques. It covers the history and wordview of traditional astrology, outlines the main geometry and number symbolism, and covers the main techniques and concepts. There is also a step by step natal interpretation outline, and there are several fully worked examples.
There is not enough in here to warrant its price and the double spacing and wide margins do not help. But the problem is the material. Obert wants to find a way to harmonize traditional and modern so much that in the process you learn nothing about the real topic: Traditional natal astrology as he throws lots of terms, faces and dignities at you but no charts (examples) from which you can see their application and learn. OTOH you do learn a lot about him, his studies and such but I can't say that is very interesting. A bad choice in this field.
As someone who went into this with only mostly the basic knowledge of a modern astrologer, I think Obert did a great job into making the information in this digestible. It was extremely helpful for me to get an understanding of some of the traditional techniques described in this book, like the symbolism in the numbers and geometry. This made me have a better grasp on how the planets communicate with each other. Astrology is a lot about reading in between the lines, so the fact that this was mostly really straight forward is a huge bonus point in itself.
Let me preface this by saying that geometry was one of my least favorite subjects in school. This book has made numbers more divine, and the author's overall holistic approach to the natal chart is inspiring. Obert finds a way to integrate traditional astrology in a way that doesn't demean modern astrologers, and his tone is more practical and less dismissive than others on the subject. I like that Obert admits to going back to adding in outer planets and psychological astrology after just focusing on traditional methods for three years.
This was required reading for Kepler 103 class, and a great bridge for modern astrologers interested in traditional techniques.
Amazing starting off point if you already have some basic knowledge of birth charts and astrology. Maybe not the best choice for absolute beginners (I think you can find more easy to digest info in other places to begin with) but if you have "dipped your feet" a little before, this book is a strong start for learning how to "swim" properly, as it has nicely structured info and it gives a lot of useful further book recommendations to continue studying traditional astrology
