If someone is concerned with their relationship with their husband or their children, then I look at the horoscopes of both and see how they interact with each other on a psychological level. The psychological forces in the personality are represented by the symbols which represent the planets. Well, I never make recommendations, because that would be directive counselling which is a bad sociological or psychological technique. And no- one chooses to feel annoyed, or chooses to feel hatred, or chooses to feel angry. These are emotions that are biophysical in their origin and which we can't control.
Some astrologers do, particularly eastern astrologers, who are fatalistic.
My own personal opinion is that there's no such thing as destiny in that it would exceed a person's innate potential for self-development. That is their potential destiny. What an astrologer tries to do is to give them sufficient insight into their potential to enable them to fulfil their destiny. But as far as each particular, specific event in their life is measurable, that's nonsense. I'm sure you've got a good point there, because most people are prone to believe in something, whether it's believing that walking under ladders will bring you bad luck or believing in the weather- forecasters or believing in the economic projections of our government statisticians and so on.
