Sword Edge structure

Meaning

The Sword Edge structure, 羊刃格 yángrèn gé, is the frame of a chart whose month branch is a yang Day Master’s Sword Edge: the branch of its Peak, where its phase is at its fullest, read as a blade rather than a summit. Like the Prosperity structure, it is named after the self rather than after a god the month brings. Ulune’s reading puts it in a sentence: it frames a life around intensity, the Day Master at the peak of its phase, decisive and bold, at its best when that edge serves a cause.

The tradition reads strength to spare and the will to use it: someone who decides, acts, defends what they value and does not give up easily. Such a chart is often the one that carries a project through, takes the hard decision, or stands up for others; its energy is that of a champion looking for a cause worth the effort.

Its difficulty is the edge itself: a strength that, without a purpose, can turn to impatience or to competing for its own sake. The classics answer with structure rather than restraint, and Ulune reads the Sword Edge as intensity and courage, never as harm.

In practice

• When Ulune names it: after the stipend test, when the month branch is a yang Day Master’s Sword Edge: Jia in Mao, Bing in Wu, Wu in Wu, Geng in You, Ren in Zi. The yin Day Masters have no Sword Edge in Ulune, so their months are read by their hidden stems.
• With strength: in season and rooted in its month, such a Day Master is always strong by Ulune’s three tests, and the favourable phases by balance are those it produces, controls and is controlled by, unless the chart is also flagged as dominant.
• What the classics look for: an Officer or Seven Killings among the stems, the power that controls the Day Master, said to hold the blade by its hilt; with them, Wealth and the Resource are both welcome. Without a controller, they read the edge by what else the chart gives it to do.
• The same branch as a star: wherever it stands, the branch is the Sword Edge star; in the month it gives this structure.
• In time, a luck pillar or a year in the Sword Edge’s branch brings the star for its while; the structure itself belongs to the birth chart.

Across traditions

• In Japan and Korea the structure is the yōjin-kaku of Shichū Suimei and the yangin-gyeok of saju.
• In Western astrology the closest picture is a planet in its exaltation, at the height of its powers, and Mars, whose classical tradition also asks that its force be given a purpose: intensity read from a planet’s place rather than from the month.

Origin and history

The Sword Edge is among the oldest signs of the Zi Ping school; the Yuanhai Ziping and the San Ming Tong Hui give its table for the five yang stems and read it, in the month, as a frame of its own. Shen Xiaozhan’s Ziping Zhenquan, in the 18th century, writes it 陽刃, the yang blade, gives it a chapter, and counts it with Seven Killings, the Hurting Officer and the partial Resource among the four forceful gods to be tempered: the blade, he teaches, wants to be held in check, and the Officer and Seven Killings both serve, with Wealth and the Resource as good companions. Xu Lewu’s commentary of 1936 kept that reading, and modern books still call a well-held Sword Edge a frame of authority.

How Ulune calculates it

After comparing the month branch with the Day Master’s stipend, Ulune compares it with a yang Day Master’s Sword Edge, the branch of its Peak stage: Mao for Jia, Wu for Bing and for Wu, You for Geng and Zi for Ren. If they match, the structure is the Sword Edge structure, whatever the hidden stems. The yin Day Masters, whose Sword Edge the books dispute, have none in Ulune’s table.
