Coming from the book I Ching (the book of changes), the Yin and the Yang are two pillars around which Chinese thought have organized for more than 3000 years, says Cyrille J.-D Javary. Showing the two slopes of the same mountain, they express the permanent change on which man has to adjust his acts. The Chinese ideogram of the Yin describes the moment when the sun passes to rain, the Yang one, the moment when we move out from the rain to go towards the sun.
Considered as "vectors" before states, Yin and Yang, which mark everything since the creation, Yin and Yang gather. Strangers to the western thought which splits and opposes, at the origin of dilemmas which found our personal tragedies, they can lead us to a unitive and harmonizing thought, to a more pacified vision of life.
