Not taking it too seriously, I still feel like atrology still is a fun thing to learn. Can anybody suggest a good reading which won't take too much time but would still give all the essential knowledge and understanding an astrologer is supposed to have? I mean the model, the formulae to calculate the deterministic part, basic clues on interpreting it etc. Isn't it fun to study magical arts which have deterministic models as important parts of them? I'm also curious about how does the rectification thing work. Astrologers say they can figure out your exact birth time given information about some events in your life.
