Since there are about 1500 variable to deal with in astrology, its no use picking up on one planetary principle alone, say Saturn square with Sun, and hoping to understand someone as a result of homing in on that. Other astrological aspects may totaly contradict that interpretation; and the final interpretation depends on a blend of factors which most of the time boils down to pure guesswork.
One school of astrologers may give a totally different interpretation on the same planetary aspect alone compared to that taught in another school. I've seen more astrologers arguing over interpretations than psychotherapists. Wonder why? Well you just can't take a degree in astrology - but you can in the medical fields which deal with the mind.
