What is Dunjia?Qi Men Dun Jia (or Qimendunjia) is one of the three most powerful oracles--Tai Yee, Liu Ren and Qi Men---to know both good luck and bad luck in aspects of time and space(direction). Tai Yee is used to divine the big events that happen with contries, such as earthquake, big hurricanes, massacre, natural disasters, etc. Qi Men is generally used for military action and take what strategic methods in ever-changing battle field. Liu Ren is mostly used for divining the general daily events which means it is close to our daily life.
Qi means mysterious or strange in usual, but here, it means valuable or holy. Men means a gate, and Dun means hidden or escaped (to make hidden), and Jia is the first one of ten stems, which is considered as the most sacred in this method.
All the three oracles use very special chart to divine and give conclusion. Yes, all of them cannot do without Heavenly stems, earthly branches, Ho drawing, Luo Drawing, Eight Trigrams, Emblematic elements and divine number, etc.
Dunjia can be divided into Year School Dunjia, Month School Dunjia, Day School Dunjia and Time School Dunjia in terms of the time. In terms of reasoning methods it should be divided into Line-Up Palace Dunjia and Jump-in-Palace Dunjia.
Here we introduce Time School Dunjia, Line-Up Palace Dunjia.
People may ask when the Dunjia came into presence and why it existed. Nowadays many people believe Dunjia originated from milatary force arrangements in the battle field and such statements gained wide approval in the scholar circle.
In the very old book The Song from Old Fishing Man carried the following story:
XuanYuan Emperor fought a fierce battle with Shi You without results for many years. In a dream he dreamed Heaven gave him an oracle and XuanYuan paid respect in a sacrifice platform and practiced such arts latter and got a final success soon after. He ordered maliatary man Feng Hou to write down the arts in words and that was the beginning of Dunjia.
Also, it was Spring and Warring Times when the so many states fought endless battles to occupy territory and there was enough demand for application of such arts.
Also the book Arts of War carried similar words concerning the theory of Dunjia. Yet, most people don't understand the meaning exactly till now.
In Three-Dynasty Times the famous military counsellor Zhu Ge Liang applied Eight Trigram Arrangement in the battle field and won many times of success.
In Dun Jia(or Dunjia) theory, we use a kind of direction chart called Pan, which is drawed as a square divided into nine blocks( 3 x 3. eight directions and centre ). In each directional block, one of the eight gates is positioned. We put away Jia(because of its holiness) and use other nine stems to put them into Dun Jia Pan chart at first, and after several process of making, Jia comes into the Pan chart from one of the eight gates. And that's why this method is called Qi Men Dun Jia.
Later due to the wide application of Dunjia this divination approach gradually broke its own boundary and gained application in disease diagnosis, business desicion, agricultural divination, etc.
Why Dunjia be Used for Divination? Any divination approaches, whatever forms they assume, are models set up to imitate the social society, the nature and the universe, etc. Dunjia is a mathematic and physical model set up by incorporating heaven aspect, earth aspect, human aspect and unexpected aspect, the time elements and space elements. There are basic nine Yang Dun Ju and nine Yin Dun Ju which provide us a dynamic unified model to imitate all transformations and changes for universal things. Therefore it can be used to divine the society, nature, individual life time or all which stays out of human's reasoning ability. By calculation we know there are altogether 216,000 Jus and ancient Chinese people hope that 216,000 Jus can imitate most part of situation in this practical world.
This is one of the most typical characteristics of Dunjia. In ancient age, those who won using Dunjia tried to keep it as top-secret, and suppressed Dunjia-masters to prevent from Dunjia-secret leaking to the enemies of the governors.
Many Dunjia-masters were arrested, but they'd never made the secret of Dunjia clear.
