Your I Ching Personalized Profile & Report is based on your birthday, location and time (if you have it). It combines various teachings, knowledge, personal experience and intuition. The profile is compatible with Astrology, any I Ching website or book, the Human Design system, the Gene Keys, personality spectrum, and Numerology. The I Ching is Chinese and the oldest of all the classical divination systems, from around 800 BCE. It is also one of the oldest books in the world and based on simple binary (what our computers are built on) with 64 themes. It provides wise and insightful answers to questions, or as a guide for contemplation.
