比肩
bǐ jiān · Companion
The Companion (比肩, bǐ jiān) is the Ten God identical to the Day Master in both element and yin-yang polarity — for a 甲 (yang wood) Day Master, another 甲. With 劫财, the opposite-polarity peer, it forms the peer pair. It is the only Ten God that neither produces the Day Master nor is produced by it, and its effect is therefore not a direction but a ratio: where the Day Master is short of what a chart asks it to carry, a Companion shares the load; where the Day Master already has enough, the same star divides one share of Wealth in two.

Why there is no 比肩格
Classical texts do not name a configuration after this star. Where a Companion holds the month branch, the Ziping Zhenquan calls the result 建禄 — the month establishing the Day Master's own 禄 — and states plainly that 禄 is the same thing as 劫, so 建禄 and 月劫 are one configuration taken by whichever stem is revealed. This site's engine follows that convention and labels the pattern 建禄格 rather than a Companion configuration, which is why a chart page names a configuration the star list does not.
The same chapter gives the condition that matters when a Wealth star is also present: using Wealth in a 禄劫 chart requires an output star, because a month-branch peer and a Wealth star control one another directly, and an Eating God or Hurting Officer is what turns the peer into a producer of Wealth instead of a competitor for it.
Worked example
Worked example (solar 1996-02-17 10:00, female, computed by this site's engine):
Pattern: 建禄格 · Strength: 中和 (engine verdicts)
A 甲 Day Master born in the 寅 month: 寅 carries 甲 as its main qi, so the Day Master's own 禄 holds the month and the engine labels the pattern 建禄格. The hour stem 己 is Direct Wealth and the year stem 丙 is an Eating God — Wealth with an output star present, which is the configuration the Ziping Zhenquan describes rather than the bare peer-against-Wealth case. The engine judges the Day Master balanced.
