The Friend is a Ten God in BaZi that represents the day master’s same-element, same-yin-yang counterpart, symbolizing peers, rivals, and self-reliance.
The Friend is derived when the day master encounters a heavenly stem or earthly branch of the same element and same yin-yang polarity, creating a mirror-like energy. This Ten God is the star of siblings, colleagues and competitors, and of independence and personal boundaries. In analysis, a balanced Friend can indicate strong teamwork, while an excess means several same-polarity peers appear with the day master.
In the Four Pillars of Destiny (BaZi), the Ten Gods classify the interactions between the day master (the self) and the other heavenly stems and earthly branches. The Friend, known as the Friend (bǐ jiān), is one of the most fundamental Ten Gods, representing the purest form of peer energy. It occurs when a stem or branch shares the same element and the same yin-yang polarity as the day master. For example, if the day master is Yang Wood (Jia), then another Yang Wood stem or a Yang Wood branch (Yin) in the chart is a Friend. This creates a relationship of equality, similarity, and potential rivalry.
The derivation is straightforward: compare the day master’s element and polarity to any other pillar’s heavenly stem or the hidden stems within earthly branches. If the element and polarity match exactly, that stem or hidden stem is a Friend. The table below illustrates common day master examples:
| day master | Friend Stem | Friend Branch (Hidden Stem) |
|---|---|---|
| Jia (Yang Wood) | Jia | Yin |
| Yi | Yi | Mao |
| Bing (Yang Fire) | Bing | Wu |
| Ding | Ding | Si |
| Wu (Yang Earth) | Wu | Chen/Xu |
| Ji | Ji | Chou/Wei |
| Geng (Yang Metal) | Geng | Shen |
| Xin (Yin Metal) | Xin | You |
| Ren (Yang Water) | Ren | Hai |
| Gui | Gui | Zi |
Note that earthly branches often contain multiple hidden stems; only the one matching the day master’s exact polarity counts as a Friend. For instance, the branch Chen contains Wu (Yang Earth), Yi (Yin Wood), and Gui (Yin Water). For a Yang Earth day master, only the Wu hidden stem is a Friend.
The Friend symbolizes the self in relation to others of equal standing. Its core meanings include:
In a chart, the Friend’s location matters. A Friend in the Year Pillar places a peer star in the ancestral palace. In the hour pillar, it sits in the palace of children and later life.
In these readings, the Friend interacts closely with the Wealth and Officer stars. Key observations:
Wealth analysis in BaZi focuses on the interaction between the day master and the Wealth star. The Friend’s role is critical:
In relationships, the Friend primarily influences dynamics with partners and peers:
When analyzing a Friend in a chart, consider the following:
The Friend is a mirror of the self in the BaZi chart, representing equality, competition, and peer relationships. It is the star of equals: peers, rivals and partners who share one pool. A balanced Friend fosters collaboration and self-reliance, while an excess calls for careful management of resources and relationships.
Both represent peers, but the Friend shares the same yin-yang polarity as the day master, while Rob Wealth has the opposite polarity. The Friend is more about equality and self-reliance, whereas Rob Wealth is the opposite-polarity peer, read as competition and cooperation over shared resources.
An excess of Friends means several peers of the same element and polarity appear with the day master. If the day master is weak, those peers support the day master; if the day master is strong, the same-polarity peer star is heavy in the chart.
For a woman, the Friend is likewise a peer star, not a spouse star. Classical texts read that as peers of the same element and polarity. The husband star remains the Direct Officer.
