THE SIGN:

Trigram Ch'ien, the Creativeabove Ch'ien the Creative, Heaven
Trigram Chên, the Arousingbelow Chên the Arousing, Thunder

Ch'ien, heaven is above; Chên, movement, is below. The lower trigram Chên is under the influence of the strong line it has received form above, from heaven. When, in accord with this, movement follows the law of heaven, man is innocent and without guile. His mind is natural and true, unshadowed by reflection or ulterior designs. For wherever conscious purpose is to be seen, there the truth and innocence of nature have been lost. Nature that is not directed by the spirit is not true but degenerate nature. Starting out with the idea of the natural, the train of thought in part goes somewhat further and thus the hexagram includes also the idea of the fundamental or unexpected.
