Astrology needs “immersion” and verification, through many comparisons, to understand how the planets work.
Some functions you only understand with time and practice, and by looking at the results on people. One example is about Saturn and Neptune, I have noticed that many people, are completely or lack of knowledge, or go “random,” or have information, knowledge, completely wrong, which causes Neptune and Saturn to weaken, bring problems in the areas they are in.
I have known people with Saturn in 2nd for example, not understanding at all the function of money and its real management, with disastrous results in their own lives. Some of them, were doing the exact opposite, of how one should manage one's economic resources.
All planets can be “positive” or “negative.” This depends on many factors. Jupiter itself identified as “benefic” and “Saturn” as “malefic,” actually both have octaves contrary to their “labels.”
With Jupiter one can experience “negativity” just as with Saturn one can experience “positivity.”
