"The Twoness of It All" (a poem)
by Moonlore,

Han-headed Cathay saw it first,
Bright as brightest solar burst;
Whipped it into boy and girl,
The blinding spiral-sliced swirl:
Yang
and Yin.

Hegel saw it, saw it clear;
Jackal Marx drew near, drew near:
O'er his shoulder saw it plain,
Turned it upside-down again:
Yang
and Yin.

Justice, tip thy scales at the Call!
One pan shall Rise, the other will Fall.
Add to A and B grows less;
A's B's partner, nontheless.
Next, the twoness that there be
In even electricity.
Chart the current as it's found:
Sine the hot lead, line the ground.
The wild sine dances, soars and falls,
But only to figures the zero calls.
Sine wave, scales, all things that be
share a reciprocity.
Male and FeMale, Light and Dark:
Name the numbers of Noah's Ark!
Yang
and Yin!

A twoness on the scene much later
Rests in your refrigerator.
Heat your house and insulate it.
Next your food: Refrigerate it.
Frost will damp your Freon coils,
So flux in Nichrome till it boils.
See the picture? Heat in cold.
In heat in cold, the story's told!
Giant-writ the sacred scrawl:
"Oh, The Twoness of It All!"
Yang
and Yin!
