The ancient Chinese developed one of the earliest binary number systems, derived from the I ching, or the book of changes, which is used in India Astrological
sometimes. This system uses two basic lines – a yin (broken line) and a yang (unbroken line) – to draw up sixty-four symbols.
The lines are first translated into numbers and then into symbolic answers to spiritual questions. According to traditional Chinese numerology, odd numbers are “yang” and masculine, and relate to heat, fire, the sun, daytime, and the color white; they also forecast good fortune.
Even numbers are “yin” and feminine, and are ascribed to cold, water, the moon, darkness, and to the color black; they relate to the earth, and symbolize openness.
In Indian Astrological, numerology is used widely in vaastu, or sacred architecture. Before a house is built, its measurements are checked carefully, as the numbers derived from each calculation are symbolic representations of gods or goddesses who can bestow good or bad fortune upon the occupant.
