River Horse Diagram, Pre-Heavenly Pa-Kua

Diagram on Horse Back River Diagram Probably before 3083 B.C., before the Yellow King reigned in 2697 B.C., there was a wise person named Fu Xi who saw a wild horse with a weird diagram on its back that jumped out from the River. The diagram implied 5 and 10 in the center, 3 and 8 on the left, 4 and 9 on the right; 2 and 7 on the top, and 1 and 6 on the bottom.

The wild horse was called Dragon Horse. The diagram on the horseback was called River Diagram.

	South Fire
East Wood	Center Earth	West Metal
	North Water

The legendary Fu Xi found the numbers in the diagram have a connection with the stars in the evening. Every year,

Mercury appeared in the northern sky in 11th and 6th months
Mar appeared in the southern sky in 2nd and 7th months
Venus appeared in the western sky in 4th and 9th months
Jupiter appeared in the eastern sky in 3rd and 8th months
Saturn appeared in the center sky in 5th and 10th months

Because the Four directions have a relationship with the Five Elements, Chinese named Venus, Mercury, Jupiter, Mar and Saturn as Metal, Water, Wood, Fire and Earth stars.

	2 7
3 8	5 10	4 9
	1 6

1 and 6 are in the north; this stands for Water
2 and 7 are in the south; this stands for Fire
3 and 8 are in the east; this stands for Wood
4 and 9 are in the west; this stands for Metal
5 and 10 are in the center; this stands for Earth

1, 3, 5, 7 and 9 are Yang (odd) numbers. 2, 4, 6, 8 and 10 are called Yin (even) numbers. 5 is the center number.

1, 2, 3 and 4 are in the inner circle. 6, 7, 8 and 9 are the outer numbers.

The inner numbers plus center number 5 are equal to the outer numbers.

Therefore 1, 2, 3 and 4 are called Heavenly Original Numbers; 6, 7, 8 and 9 are called Earthly Developed Numbers.

The sum from 1 to 10 is 55, which is called Heavenly Number. 5 is the center number of 1, 3, 5, 7 and 9 yang numbers. Also, 5 connects with many arithmetic calculations, 5 becomes the secret index of Heaven from the hint of the River Diagram. That's why the day system in the Chinese calendar used a cycle of 5 before.

After applying the Five Elements on the River Diagram, we find the Five Elements Producing Relationship shows in a clockwise direction.

That's why the Number Relationships are applied on the Chinese Five Elements astrology by Five Element scholars later.

I Ching Pa Kua (Eight Trigrams)

The River Diagram derived the Pre-Heaven Pa Kua.

Fu Xi thought that

is one, stands for the sky;

is two, stands for the earth. One pluses two is

three, which can be the symbol of sky and earth.

We call this symbol Trigram. is three Yang, stands for Heaven on the top of the sky. is three Yin, six bars, stands for earth on the ground bottom.
