A beam or pillar can be used to batter down a city wall, but it is no good for stopping up a little hole - this refers to a difference in function. Thoroughbreds like Qiji and Hualiu could gallop a thousand li in one day, but when it came to catching rats they were no match for the wildcat or the weasel - this refers to a difference in skill. The horned owl catches fleas at night and can spot the tip of a hair, but when daylight comes, no matter how wide it opens its eyes, it cannot see a mound or a hill - this refers to a difference in nature. Now do you say, that you are going to make Right your master and do away with Wrong, or make Order your master and do away with Disorder? If you do, then you have not understood the principle of heaven and earth or the nature of the ten thousand things. This is like saying that you are going to make Heaven your master and do away with Earth, or make Yin your master and do away with Yang. Obviously it is impossible.

On the blank leaf glued to the inner back cover I drew the double curve within the circle, and blacked the yin half of the symbol, then pushed it back to my companion. 'Do you know that sign?'

He looked at it a long time with a strange look, but he said, 'No.'

'It's found on Earth, and on Hain-Davenant, and on Chiffewar. It is yin and yang. Light is the left hand of darkness... how did it go? Light, dark. Fear, courage. Cold, warmth. Female, male. It is yourself, Therem. Both and one. A shadow on snow.'

So it is said, for him who understands Heavenly joy, life is the working of Heaven; death is the transformation of things. In stillness, he and the yin share a single Virtue; in motion, he and the yang share a single flow.

À l’époque primordiale, l’homme était, en lui-même, parfaitement équilibré quant au complémentarisme du yin et du yang ; d’autre part, il était yin ou passif par rapport au Principe seul, et yang ou actif par rapport au Cosmos ou à l’ensemble des choses manifestées ; il se tournait donc naturellement vers le Nord, qui est yin, comme vers son propre complémentaire. Au contraire, l’homme des époques ultérieures, par suite de la dégénérescence spirituelle qui correspond à la marche descendante du cycle, est devenu yin par rapport au Cosmos ; il doit donc se tourner vers le Sud, qui est yang, pour en recevoir les influences du principe complémentaire de celui qui est devenu prédominant en lui, et pour rétablir, dans la mesure du possible, l’équilibre entre le yin et le yang. La première de ces deux orientations peut être dite « polaire », tandis que la seconde est proprement « solaire » : dans le premier cas, l’homme, regardant l’Étoile polaire ou le « faîte du Ciel », a l’Est à sa droite et l’Ouest à sa gauche ; dans le second cas, regardant le Soleil au méridien, il a au contraire l’Est à sa gauche et l’Ouest à sa droite ; et ceci donne l’explication d’une particularité qui, dans la tradition extrême-orientale, peut paraître assez étrange à ceux qui n’en connaissent pas la raison

All being, it seemed, was built on opposites, on division. Man or woman, vagabond or citizen, lover or thinker — no breath could both be in and out, none could be man and wife, free and yet orderly, knowing the urge of life and the joy of intellect. Always the one paid for the other, though each was equally precious and essential.

Your greatest attribute, that which allows you to accomplish most in life and the most treasured aspect of your being will often be the source of your greatest suffering.
