# Ziwei doushu

Ziwei doushu, sometimes translated into English as purple star astrology, is a form of fortune-telling in Chinese culture. The study of destiny (Chinese: 命學; pinyin: mìngxué) is one of the five arts of Chinese metaphysics. Along with the Four Pillars of Destiny, ziwei doushu is one of the most renowned fortune-telling methods used in this study. Much like western astrology, ziwei doushu claims to use the position of the cosmos at the time of one's birth to make determinations about personality, career and marriage prospects, and more.

## History

Traditionally, ziwei doushu is considered to have been created by a Taoist named Lu Chun Yang (呂純陽) during the Tang dynasty. It was further developed by Chen Xi Yi (陳希夷) during the Song dynasty and later on by Luo Hong Xian (羅洪先) during the Ming dynasty to its present-day form. Its exact origin, however, is still debated among different schools.
Unlike the more commonly known Four Pillars of Destiny system of birth-chart divination, ziwei doushu is based on a purely lunar calendar and the position of the night sky. By contrast, Bazi is tied to the sexagenary cycle system of timekeeping, which is often mapped to traditional Chinese solar terms. Some believe that this difference makes the two systems complementary rather than competitors.
The study of destiny (Chinese: 命學; pinyin: mìngxué), of which ziwei doushu is a part, has traditionally been closely intertwined with astronomy. Historically, gifted astronomers and astrologers were recruited as officials to work in Imperial Courts during the dynastic eras, producing astrological charts for the emperor, as his personal fate had a direct bearing on his kingdom. The court astrologers also played an important role in determining the successor to the throne.
Astrologers observed the stars and noticed that among so many stars, only one was seemingly stationary while the rest revolved around it. This star was named the 'Emperor star' (紫微星)—the celestial equivalent of the Emperor and known in the West as Polaris. While this star in ziwei doushu has a physical basis, the rest of the system's "stars" are expressions of the cyclical passage of time and do not necessarily represent physical stars in the sky.
As with many other forms of fortune-telling, practitioners do not generally see the natal chart as an infallible guide as to what will happen, but more as a form of forecasting in detail. Destiny and fortune are considered structurally complex and are unlikely to be changed by a single element. An overly simplistic application of – for example – changing one's lucky colors and numbers is not expected to affect or change one's destiny in any significant way. However, practitioners believe that knowledge about future possibilities may allow one to gauge the situation in advance and make decisions from a position of strength. Ziwei doushu approaches the world and events from the idea that to view things in their proper context, it is important to recognise the "spiritual dynamic of the universe" to find the pattern of change that leads to "fundamental truth".

## Chart structure

The 12 Palaces (十二宫) are arranged and plotted in an anti-clockwise rotation. The presence of certain stars in each palace can be considered either an auspicious or inauspicious omen regarding that part of one's life. In some lineages, these palaces are also assigned phases based on the sexagenary cycle which is also used in Four Pillars of Destiny reading.
* Self Palace (命宮)
* Siblings Palace (兄弟宮)
* Spouse Palace (夫妻宮)
* Children Palace (子女宮)
* Wealth Palace (財帛宮)
* Health Palace (疾厄宮)
* Travel Palace (遷移宮)
* Friends Palace, or Subordinate Palace (交友宮)
* Career Palace (官祿宮)
* Property Palace (田宅宮)
* Mental Palace, or Karma Palace, Ancestor Palace (福德宮)
* Parents Palace (父母宮)
