Before you can detect a { CHANGE } , you must first recognize a [ difference ] .
In the 'I-CHING', the [ difference ] is expressed via the a pair of 'opposite' symbols --- the { 'YIN Line' } vs. the { 'YANG Line' } :
In general,
or { 'YIN' } , represents 'Darkness', 'Coldness', the 'Negative', the 'Passive', etc.,
or { 'YANG' } , represents 'Brightness', 'Warmth' , the 'Positive', the 'Active', etc..
A Trigram is simply a set of three (3) { 'YIN' or 'YANG' Lines } , arranged in a vertical order.
The eight (8) Trigrams, are as follows :
| Tri- gram | Name of Trigram | Assigned Meaning | the 'ICG' designation | |
|---|---|---|---|---|
| 1 | ![]() | - qian | - heaven | T1 |
| 2 | ![]() | - dui | - lake | T2 |
| 3 | ![]() | - li | - fire | T3 |
| 4 | ![]() | - zhen | - thunder | T4 |
| 5 | ![]() | - xun | - wind | T5 |
| 6 | ![]() | - kan | - water | T6 |
| 7 | ![]() | - gen | - mountain | T7 |
| 8 | ![]() | - kun | - earth | T8 |
And a Trigram is always read from the bottom-line upwards, as per this example below :
A Hexagram is simply a set of six (6) { 'YIN' or 'YANG' Lines } , arranged in a vertical order.
And a Hexagram is often viewed as [ one Trigram stacked on-top-of another Trigram ] :

We have marked in this table, ( in darker-colors and in pairs ) , the Hexagrams whose pronunciations are very similar in Chinese ( Putonghua / Mandarin ) .
Thus, identifying the 64 Hexagrams via [ citing their names only ] may often lack the precisions required.
In the [ ICG Approach ] , we shall identify each Hexagram :
EITHER :
OR :
e.g. : the Hexagram { HEAVEN } ,
, will be designated as [ T1-T1 ] .
We note here that a Hexagram is also always read from the bottom upwards, as per this example below :

The 'I-CHING' was created early in Chinese history and the three (3) relevent periods are :
| 1. | XIA Dynasty | ![]() | - circa [ 21th Century B.C. ] to [ 16th Century B.C. ] |
| 2. | SHANG Dynasty | ![]() | - circa [ 16th Century B.C. ] to [ 1066 B.C. ] |
| 3. | ZHOU Dynasty | ![]() | - circa 1066 B.C. to 256 B.C. |
, or FU XI , the legendary author of the 8 Trigrams, lived in the times before the [ XIA Dynasty ] .
And there are three (3) versions of the 'I-CHING' :
: The 1st version was the { Connedcted-Hill-I } in the [ XIA Dynasty ] .
: The 2nd version was the { Return-Hidden/Treasure-I } in the [ SHANG Dynasty ] .
: The 3rd version was the { ZHOU-I } in the [ ZHOU Dynasty ] .
, or WEN WANG ( King Wan ) , the author of the { ZHOU-I } , is the father of the founding king of the [ ZHOU Dynasty ] ,
Several things to note here :
to Chinese Characters
.
Authenticity & interpretation may always be problems here.
- MOUNTAIN was the first-listed Trigram in the [ Connected-Hill-I ] ,
- EARTH was the first-listed Trigram in the [ Return-Hidden/Treasure-I ] ,
- HEAVEN is the first-listed Trigram in the [ ZHOU-I ] .
Each version of the 'I-CHING' therefore took on a slightly different emphasis.
) and the readings therefrom are interpreted thru the 'I-CHING' .
The 'I-CHING' is therefore an integral part of early Chinese Life, Culture & History.
, or Confucius ( circa 511 B.C. - 479 B.C. ) have added his thoughts on the 'I-CHING' in his writings, the [ Ten Wings ] (
) .
And these are usually included as part of the 'I-CHING' .
