Astrology was born not as a form of entertainment or as a scheme for fortune telling, but as a vital tool for survival. With the advent of agriculture, humans adapted their planting and harvesting routines to the dictates of the seasons. The measuring of time-the fluctuations in darkness and daylight, the arrivals of the winter and summer solstices, the great rivers' tides and flooding-became essential to a successful harvest. In our day and age, it is important to attune our lives to the repetitive rhythm of the seasons and the orbits of the planets.
