Astrology can help you to maximize your potential for optimum health by making certain dietary recommendations and by suggesting physical activities that will be appealing. Astrology can help you to choose a good spot to live. Astrology suggest not only compatible countries, states and cities, but also compatible surroundings and even street addresses. Astrology can help you to create the future. An astrologer can help an auspicious time to open a business, start a corporation, issue an important mailing, have a wedding ceremony, have a caesarean birth and countless other activities.
Astrologers can do a bit of everything, because they can offer insight into anything.
No, astrologers aren't know it alls, and they aren't dilettantes. Astrology is the most potent form of unified field theory. Astrology is a language, not a belief system. People no more have to believe in astrology than they do in, say, cordless telephones. You can get the call through without believing.
