My dearest Amzolt,
You have (possibly inadvertently!) raised an interesting question. Are the aspects that *make*a person good at astrology ALSO the aspects that generate psychic ability?
It's true that there are some astrologers who ARE also psychic. (I guess that's just their good luck to be gifted in that way) BUT,there are also excellent (predictive) astrologers who are NOT psychic.
I don't think astrology has anything to do with *guessing*.If you scrutinise a chart in enough detail, taking into account signs, aspects to planets, aspects to house cusps, midpoints, transits, solar return, lunar return, age harmonic etc etc etc and have a mind sufficiently developed to integrate and interpret that information, theoretically you would have a very proficient predictive astrologer.
If you watch what happened *last time* you had a certain transit, its not that hard over time and with practice to *predict* what might happen *next time* you have that transit. In that way one can predict for oneself.The more often one practises something, the more proficient one becomes.
I take your point about an aspect having more than one possible application/manifestation.A mars sun square will not be the same for everyone, but if you analyse that transit in relation to its integral involvement in the chart the following things for example could well be *predictable*:-
birth of a child, meeting of a partner, purchase of property,overseas travel, gain of inheritance, new job, separation/death of parents, ill health, surgery,arrest,marriage, etc etc etc.
This kind of predictive astrology is practised successfully every day even by relatively inexperienced astrologers and has been for at least hundreds of years.
If I recall correctly it was Astrologers who predicted the birth of Christ.They might have been channelling I guess.
