First, welcome to our EA community. I remember Wolf saying many times that his easiest students were the ones who had not read much in astrology BECAUSE THERE WAS THEN LESS TO UNLEARN. You will find that if you read his two book on Pluto, his daughter Deva's book, and as yo go but the various DVD's, transcripts, and audio tapes on this website of Wolf's various lectures that you will learn all you need to learn not only about EA, but astrology itself.
And, of course, by coming to this message board and reading through everything that has already been posted, keeping current with ongoing posts, and posting your own questions as they emerge, as you go along, that the totality of this will give you a total basis for EA, and astrology. Then, as some point, to purchase the actual EA school that Wolf taught many years ago which, of course, it utterly comprehensive in Evolutionary Astrology.
Again, welcome and God Bless, Rad
