What is I-ching (Book of Changes)?

I-ching or the Book of Changes is an ancient divination book aiming at the use of Chinese emperors and princes.
It consists of 64 short essays on the lineal figures named hexagrams.
Each hexagram is made of six yin and/or yang lines as shown below:

__  __
__  __
_____  Hexagram 54 - Kuei Mei / The Marrying Maiden
__  __
_____
_____

The yin is represented by a broken  line__  __ and the yang as a continuous _____ one.
Each hexagram has a name (tag).
Each name points to a specific life situation, human attitude or object.
Each hexagram is assigned a so-called Judgment in the form of a short statement sometime followed by an advice.
The statement refers to the future and is related to the consulter question. The advice instruct the consulter on how to act in order to avoid a danger or attain his/her goal.
