I'm sorry about the confusion (english is not my primary language), I wasn't being sarcastic... What I wanted to say was that I couldn't get a guide to study astrology (it's also my weekness), like there are to meditations or even yoga ... and I know there are a lot of jew corrupted info on the internet, so I don't know what else to reccomand other than JoS...I personally find astrology very hard to learn, since every detail is very important, but a very good skill if mastered... I think it really takes some good 1-3 years before one can become good in this domain, since it's by no means easy.
Also I was reading that the original astrology was with 13 signs, instead of 12... the 13th was ophiucus "the serpent bearer"... so it's very confusing were to start and how to progress in the most efficent way, but with strong desire everything is possible.
Good luck with studying!
