Renaissance philosophers and sages explained astrology through a number of principles all based on the harmony and sympathy of the Cosmos. First, “As Above, So Below”, in other words the cycles of the heavens reflect the cycles taking place here on Earth. Second, the beginning of anything shows how it will grow, develop and end. Acorns don’t grow into anything other than oaks. This explains how our birth horoscopes can foretell our character and the events of our lives. By examining the position, state and interactions of the planets at the exact time, date and place of our birth we see the seed elements which will develop in our lives.

A horary chart is an accurate chart of the position, state and interactions of the planets at the birth, not of a person or thing, but of a question. The order and sympathy of the Cosmos is so perfect that the Mind and Will of the querent asking a serious question and the alignment of the planets coincide, allowing the question to be judged from a horary chart.
