From Lieh-tzu: A Taoist Guide to Practical Living:
Po-lo sighed and said, "His skill has risen beyond my imagination. His ability is now at least ten thousand times better than mine. For while I still judge a horse by nuances in appearance, he can see beyond appearance. When he sees a horse, he does not see male or female, black or yellow. He sees the essence of the horse directly. When one can see that way, external features are unimportant. The important thing about the horse is its potential, not whether it is a mare or stallion, or has a yellow or black coat."
When the horse was trained, the king found that he possessed the best horse in the country.
