Your I Ching Personalized Profile is based on your birthday, location and time (if you have it). The profile is compatible with Astrology, any I Ching website or book, the Human Design system, the Gene Keys. 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. Read more about the I Ching, and the Profiles and Reports here.
