## THE GREAT MONAD.

(

Various Dissection Puzzles)

Here is a symbol of tremendous antiquity which is worthy of notice. It

is borne on the Korean ensign and merchant flag, and has been adopted as

a trade sign by the Northern Pacific Railroad Company, though probably

few are aware that it is the Great Monad, as shown in the sketch below.

This sign is to the Chinaman what the cross is to the Christian. It is

the sign of Deity and eternity, while the two parts into which the

circle is divided are called the Yin and the Yan--the male and female

forces of nature. A writer on the subject more than three thousand years

ago is reported to have said in reference to it: "The illimitable

produces the great extreme. The great extreme produces the two

principles. The two principles produce the four quarters, and from the

four quarters we develop the quadrature of the eight diagrams of

Feuh-hi." I hope readers will not ask me to explain this, for I have not

the slightest idea what it means. Yet I am persuaded that for ages the

symbol has had occult and probably mathematical meanings for the

esoteric student.

I will introduce the Monad in its elementary form. Here are three easy

questions respecting this great symbol:--

(I.) Which has the greater area, the inner circle containing the Yin and

the Yan, or the outer ring?

(II.) Divide the Yin and the Yan into four pieces of the same size and

shape by one cut.

(III.) Divide the Yin and the Yan into four pieces of the same size, but

different shape, by one straight cut.
