Zi Wei Dou Shu (Purple Star Astrology) · Major star 6 of 14

Lian Zhen 廉貞, the double-edged fire star

Lian Zhen 廉貞 is the fifth star of the Northern Dipper in the 紫微斗數全書 and the last of the Zi Wei series, eight palaces behind Zi Wei. The text calls it the star that governs rank in the Dipper and authority in the chart, and is harsher with it than with almost any other.

The twelve palaces of the board, 巳 午 未 申 along the top, 辰 and 卯 down the left, 酉 and 戌 down the right and 寅 丑 子 亥 along the bottom, each marked with Lian Zhen's brightness there by the 全書's seven-level table: brilliant (廟) in 寅, 申; weak or fallen in 巳, 亥. The brilliant palaces are outlined, and 廉貞 is written in the centre. 子 平 neutral 丑 利 beneficial 寅 廟 brilliant 卯 平 neutral 辰 利 beneficial 巳 陷 fallen 午 平 neutral 未 利 beneficial 申 廟 brilliant 酉 平 neutral 戌 利 beneficial 亥 陷 fallen 廉貞
Lian Zhen's brightness in each of the twelve palaces, by the 全書's seven-level table: the brilliant palaces outlined, the weak and fallen ones dashed. 寅 sits at the bottom left, as charts draw the board.

Meaning

The 全書's dialogue begins:

廉貞屬火,北斗第五星也。在斗司品秩,在數司權令。

In our translation: Lian Zhen belongs to fire, the fifth star of the Northern Dipper. In the Dipper it governs rank and grade; in the numbers, authority and command.

No star gets a sharper portrait. Its epithet is 囚, confinement, and when it stands in a weak palace the text says it 「化囚為殺」, turns from confinement into killing: a blessing that cannot be measured, a harm that cannot be undone. Its company changes it more than its place. 「逢帝座執威權,[…]遇文昌好禮樂」: beside the emperor it wields authority, and with Wen Chang it loves rites and music (with its line on 富貴 left out). In the Life or Body palace it is the "second peach blossom", after Tan Lang.

The 形性賦 gives it broad brows, a wide mouth and 「為人性暴,好忿好爭」, a hot temper, quick to anger and to quarrel: a type, never a reading of anyone's body or character.

Our chart calls it Integrity, after the first character, 廉, incorruptible; the second, 貞, steadfast or chaste, is why English Wikipedia says Chastity, a name we avoid because it misleads. Our gloss reads: intense and principled yet passionate; ambition needing self-control.

The name

廉貞 is the Sui 五行大義's name for the fifth star of the Northern Dipper, 玉衡 (Alioth), and the Daoist Northern Dipper scripture repeats it. On the board it is placed by counting; nothing is observed. Chinese feng shui gives the name to the number five of the nine stars, the star Nine Star Ki calls Five Yellow Earth.

On the board

Lian Zhen is eight palaces behind Zi Wei, which is four ahead of it. It shares a palace with Tian Xiang in 子 or 午, Qi Sha in 丑 or 未, Po Jun in 卯 or 酉, Tian Fu in 辰 or 戌 and Tan Lang in 巳 or 亥, and stands alone in 寅 and 申, where it is brilliant (廟). It is fallen (陷) in 巳 and 亥. In the common table it takes 化祿 in a 甲 year and 化忌 in a 丙 year. It is the Life Master (命主) when the Life Palace is in 辰 or 申.

What this page leaves out

The 全書's dialogue on Lian Zhen runs through gambling, lawsuits, injuries and worse. We note that the text speaks so, more of this star than of any other, and repeat none of it.

How the schools read it

紫微斗數全書, 諸星問答論
Governs rank in the Dipper and authority in the chart; "beside the emperor it wields authority ... with Wen Chang it loves rites and music". Not bright, it "turns from confinement into killing".
紫微斗數全書, 形性賦
Broad brows and a wide mouth; "a hot-tempered person, quick to anger and to quarrel". A sketch of a type, never a reading of anyone's body.
紫微斗數全書, the dialogue on the Life palace
In the Life or Body palace it is the "second peach blossom" (次桃花), after Tan Lang: a star of attraction, in the text's idiom.
Three-harmony practice (三合派)
Reads it above all by its company: with Zi Wei, with Tian Fu or Tian Xiang, with Tan Lang, Qi Sha or Po Jun, the star takes a different colour.
English teaching
Chastity, Integrity, Pride, Reformer, Judge: the names pull in different directions, as the two characters do.
EsoTerrier
Short name Integrity; our gloss keeps the double edge, ambition that needs self-control. No reading of outcome.

Claims about it

  • Lian Zhen is the fifth Dipper star, and the chart reads where it stands.

    disputed

    What the record shows: The name is the fifth Dipper star's in the Sui 五行大義; the chart places Lian Zhen by counting from Zi Wei and observes nothing.

  • The text's lines on Lian Zhen foretell disputes, punishment and bloodshed.

    unverified

    What the record shows: The 全書 speaks that way about this star more than any other. Those lines are its historical language, and none of them is ours.

  • Lian Zhen is a Northern Dipper star because it belongs to the Zi Wei series.

    false

    What the record shows: Its Dipper seat comes from its name; the series is a placement grouping.
