I CHING PRIMAL ARRANGEMENT

Each of these modules symbolizes a unit measurement from one to nine. Since the number five represents the earth in the middle of all the numbers, and man, it is left out. Each unit extends in only one direction as a line. Even numbers represent heaven, odd numbers represent earth...
"Water in the north has sprung from one of heaven, which is complemented by the six of earth. Fire in the south has sprung from the two of earth, which is complemented by the seven of heaven. Wood in the east has sprung from the three of heaven, which is complemented by the eight of earth. Metal in the west has sprung from the four of earth, which is complemented by nine of heaven. Earth in the middle... has sprung from the five of heaven, which is complemented by the ten of earth."
