Yin Yang.

Light verse dark,

In everything that is light,
There is darkness,
In everything that is dark,
There is light,

Without the dark,
There can not be the light,
Without the light,
There can not be the dark,

Good verse evil,

In everything that is evil,
There is good,
In everything that is good,
There is evil,

Without evilness,
There can not be goodness,
Without goodness,
There can not be evilness,

Black verse white,

In everything that is black,
There is white,
In everything that is white,
There is black,

Without black,
There can not be white,
Without white,
There can not be black

Without one,
The other can not exist,

Dark and light,
Good and evil,
Black and white,

All live together,
None are separated.
