The ten thousand things carry yin and embrace yang.
They achieve harmony by combining these forces.
Men hate to be “orphaned,” “widowed,” or “worthless,”
But this is how kings and lords describe themselves.
For one gains by losing
And loses by gaining.
What others teach, I also teach; that is:
“A violent man will die a violent death!”
This will be the essence of my teaching.
Lao Tsu, Tao Te Ching
