How To Astrology - Human Ethics

Given that astrology is neither exact science, nor a religious doctrine, it is not obvious what it has to say about good or evil, or the nature of human experience, meaning of life, these sorts of things. Since I do maintain that astrology is not a collection of random nonsense either, there must be some value judgments involved, or insight into who we are and how we should live. After all, astrology does focus specifically on the composition of human soul and the meaning of events made manifest.
