There is a side of the Moon which we never see, but that hidden half is as potent a factor in causing the ebb and flow of the earth's tide, as the part of the Moon which is visible. Similarly, there is an invisible part of man which exerts a powerful influence in life, and as the tides are measured by the motion of the Sun and Moon, so also the eventualities of existence are measured by the circling stars, which may therefore be called the "Clock of Destiny," and knowledge of their import is an immense power, for to the competent astrologer the horoscope reveals every secret of life. This book and the simplified method it contains of casting a horoscope in a thoroughly scientific manner is published in order to enable anyone who can add and subtract to do the work himself, instead of relying on others. Thus he will obtain a deeper knowledge of the causes which are operative in life than any professional astrologer who is a stranger can give.
