New Avatar Power is a great book with a growing userbase. I had never heard of it until I came here.
The book appears cheesy, with a 70's infomercial vibe, but it is actually very good, and a good bit of the information in it is simplified examples of Biblically dervied work from Paracelsus, Agrippa, and other classical sources.
It is a gateway book into occult study, and a very good one if you can get past the 70's vibe. But if you get into this, and it receives praises of success from many people who attempt to use it.
I form the light, and create darkness: I make peace, and create evil: I YHVH do all these things.
