What is I-ching (Book of Changes)?

I-ching or the Book of Changes is an ancient divination book used by the 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 in the example 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 regarding the issue of a future intended action. For example one wishes to marry or move to another place, start something new or cure a disease and so forth.
The statement refers to the outcome of the question and may instruct one on how to act in order to avoid a danger or attain his goal.

Methods of divination
One may consult the I-ching oracle by casting coins or yarrows or even online through this device (see the instruction on the left).
