The western form of Numerology, the Pythagorian system, is among the most enduring and popular of all self-help methods ever created. The Chinese, Japanese, Greek, Hebrews, Egyptians, Phoenicians, early Christians, Mayans and Incas all employed number systems to gain a deeper understanding of themselves and the universe. Pythagorian Numerology was organized by Greek philosopher and mathematician Pythagoras, who combined the mathematical disciplines of the Arabic, Druid, Phoenician, Egyptian and Essene sciences. Since then, it has continued to evolve. It formed the spiritual basis for many secret societies, such as the Rosicrusians, Masons, Anthroposophists and others. Today, its popularity continues to grow. Numerology columns now appear regularly in newspapers and magazines. Numerologists are consulted with increasing regularity for everything from personal romance to business decisions. As the industrialized world becomes more computerized and dependent on numerical systems, the fascination with this ancient spiritual science only grows.
