Yi Jing, Oracle of the Moon

Luoshu oracle (a trigram oracle)

  The oracle itself is not old, but the layout is an ancient map of the earth. In China it is the layout of the Luoshu magic square, nowadays worldwide known as the basic stucture of Feng Shui, the art of creating a harmonious environment.
  Both in the East and the West magic squares intrigued people since old times.
The most well-known one is the magic square of Saturn, planet of law and order and solid structures. Nowadays it is worldwide known as the basic structure of Feng Shui.

  The green lines in the square of Saturn (at left) are an old symbol for the planet Saturn. But when you follow the numbers in the Magic Square of 9 at right (or the Luoshu magic square in the center), the same symbol will emerge.
  In astrology, Saturn is a planet associated with discipline, responsibility, structure, limitations and boundaries.
  In Fengshui, living according to your reality is the way to find prosperity and happiness. It is the art of creating a harmonious environment.
  It is a great way to consult an oracle - laying trigrams out on (or imbedding them in) the pattern of your life and character.
