取义

In the system of the Six Harms, the relation between 子 and 未 is characterized by the mutual impairment of two forceful agents. 未 is the earth branch at the height of its seasonal abundance, while 子 belongs to the strongest phase of water. In classical discussion, 亥 and 子 are grouped together as prosperous water, and when that vigorous water meets the flourishing earth of 未, neither element can subdue the other. The result is not a clean victory of one force over the other, but a state of mutual obstruction.

The traditional name for this pairing is 势家相害, meaning harm between powerful houses or harm between forces of comparable strength. This designation appears in the discussion of the Six Harms in the Sanming Tonghui. The term reflects the underlying view that 子未害 arises not from weakness, but from the collision of two branches each unwilling to yield.

由冲合而生

The Six Harms are not an independent system parallel to the Six Clashes and the Six Combinations. Rather, they are generated through the interplay of clash and combination. The 子未 pairing is explained through the relationship among 子,午, and 未.

子 stands in direct clash with 午. At the same time, 午 and 未 form a combination. In this configuration, 子 fears the clash brought by 午, while 未 draws 午 away through combination. The traditional formulation states that before the bond of kindness is formed, enmity has already arisen. In other words, 未 removes the branch that 子 regards as its opponent, but does so in a way that leaves 子 harmed rather than relieved. The harm is therefore indirect: it is produced by the prior logic of clash and combination, not by a direct attack between 子 and 未 themselves.

This derivation is essential to understanding why the Six Harms occupy a subordinate position in traditional practice. They are secondary formations emerging from the more fundamental operations of clash and combination. Where clash and combination are visible and direct, the harms operate beneath the surface.

位置与轻重

The Sanming Tonghui, in its chapter on the Six Harms, states that the most important placement for a harm is between the day pillar and the hour pillar. When the day branch and the hour branch form a harmful relation, the connection is considered especially significant because it binds the person to the later part of life and to outward activity. The next level of importance is assigned to the body and life palace positions, where the harm may indicate a less immediate but still relevant undercurrent.

In general, however, the Six Harms are held to be weaker in force than the clashes and combinations of the earthly branches. Their influence is typically described as hidden disharmony or covert friction. A harm does not produce the open rupture associated with a clash, nor the binding attraction associated with a combination. Instead, it suggests quiet interference, latent resentment, or a relationship in which each party inadvertently undermines the other.

Because of this subdued character, the Six Harms are treated in traditional practice as an auxiliary reference. They are not used independently as the primary basis for judging fortune or misfortune. A harmful relation may color a situation, but it does not by itself establish a decisive outcome. Its role is to refine or complicate a reading already shaped by stronger structural factors.

The activation of a harm also depends on the presence of both branches. If the natal chart contains only one of the two branches in the 子未 pair, the harm is not yet formed. The relation becomes operative only when a later annual or decennial cycle brings the missing branch. At that point, the two branches meet and the harm is said to be established. Until then, the potential for harm remains latent.

命例

Four pillars: 辛丑,庚子,庚子,癸未. Pattern: 伤官格. In this chart, the month branch is 子 and the hour branch is 未, so the 子未害 relation falls on the month and hour pillars.

The presence of 子 in the month and 未 in the hour places the harm across the middle and later portions of the chart. Since the day and hour connection is emphasized in traditional discussion, the hour 未 forms a potentially significant relation with the 子 branches in the chart. The harm here does not arise from a single meeting alone; the month 子 and the hour 未 stand at a distance, with the day branch also occupied by 子. This repetition of 子 strengthens the water element in the chart, while 未 stands as the sole representative of the earth branch in this pairing.

Under the logic of 势家相害, the two sides are both substantial. The repeated presence of 子 indicates that water is prominent, while 未, as the mature earth of late summer, is not easily overwhelmed. The relation therefore suggests a quiet tension between the strong water configuration and the isolated but resilient earth position. In practice, this would be read as an auxiliary factor alongside the chart's pattern of 伤官格, not as the primary determinant of the chart's character.

常见误区

A common misunderstanding is to treat the Six Harms as equivalent in force to the Six Clashes or the Six Combinations. This is not accurate. The harms are derivative formations, and their effect is generally more muted. They describe friction rather than rupture, and their presence should not be read as a direct sign of major disruption.

Another error is to interpret 子未害 as a simple elemental conflict between water and earth. While water and earth are involved, the traditional explanation is more specific. The harm is not merely the natural opposition of water and earth, but the particular indirect configuration arising from the clash between 子 and 午 and the combination between 午 and 未. Without that intermediary structure, the pairing of 子 and 未 would not carry the same meaning.

It is also mistaken to assume that a harm exists in a chart whenever one of the two branches appears. The relation requires both branches to be present, whether in the natal pillars or through the arrival of a later cycle. A single branch alone does not constitute the harm.

Finally, the Six Harms should not be used as the sole basis for a life reading. Their traditional function is to add nuance to a chart already interpreted through stronger frameworks such as the month pattern, the day master, and the major clashes and combinations. When a harm appears, it may indicate a hidden source of strain, but it does not by itself determine the overall direction of the chart.
