  • Astrology has had a revered place in most ancient cultures. While modern science, and Western religions throughout the ages, have been adversarial to astrology, and created a disparaging view of astrology, with the advent of personal computer astrology software and accurate birth times (the Achilles Heel of natal astrology is the dependency upon accurate birth times), astrology is experiencing a renascence.

    There are now many different and active schools of astrology including Vedic, Modern Western, Medieval, Cosmobiology, Hellenistic, Huber, Chinese, Tibetan, Mayan, and more.
