There are many BOOKS about astrology that prove that astrology works. So far, I have not seen a single one that explains w h y it works. After all, the distances between an earthling and the cosmic bodies, which are the determining factors of a horoscope, are immense. It makes sense that the sun and the moon influence life on earth because of their relative proximity and the radiation coming from them. It dos not make sense that, for instance, the planet Pluto, which is a small object at the outer limits of the solar system, should affect life on earth. And yet it can have profound effects on someone's life because this planet moves so slowly that its influence through a specific aspect.
2 Depending on the attacking planet, until the final result is reached this can be an "on again off again" situation, Pluto; a sudden totally unexpected and severe definite blow, Uranus; deceit, delusions and treachery, Neptune; misfortune, losses, and health problems, Saturn; miscalculations, bad judgement, wishful thinking gone wrong, loss of money, investments gone bad, infidelity etc. Jupiter. - Please note that this is just an example. To interpret a horoscope thoroughly the nature of the participating planets has to be considered according to their locations in signs and houses of the natal chart and their aspects.
