Wood (木)

Wood (木, Mù) is the first of the Five Elements, and the easiest to feel: it is the energy of spring, of the seedling forcing its way up through soil toward light. In Bazi it is the principle of growth, expansion, and forward motion — the will to rise and to keep rising. Its classical virtue is 仁 (benevolence), the outward, life-giving instinct of something that grows by helping other things grow.

A chart's Wood describes vision and direction: the capacity to plan, to begin, to push toward a future that isn't here yet. Where Metal cuts and Earth settles, Wood reaches. It carries kindness and idealism, but also the stubbornness of a tree that has decided which way is up and will not be talked out of it.

Wood comes in two Heavenly Stems: Yang Wood (甲), the standing timber — the tall tree and load-bearing beam, upright and slow-growing — and Yin Wood (乙), the climbing vine, pliant and persistent, growing around obstacles rather than through them. Same element, two strategies for the same upward drive.

In the generating cycle (相生), Wood is produced by Water — rain and groundwater feed the tree — and Wood in turn produces Fire, since wood is what fire burns. So a chart reads Water as Wood's source and Fire as its outlet: where the growth is nourished from, and where it expresses itself.

In the controlling cycle (相剋), Wood controls Earth — roots break and hold the soil — and Wood is controlled by Metal, the axe and blade that prunes or fells it. These four relationships (fed by Water, feeding Fire, controlling Earth, checked by Metal) are how any element is actually read in a chart: never alone, always as a node in a web of support and restraint.

A chart strong in Wood tends to read as growth-oriented and directional — planners, builders, idealists, people with a clear sense of where they are headed and the patience to get there. Weak or absent Wood can read as a lack of direction or initiative, a difficulty starting things or imagining a different future. Excess Wood, unchecked by Metal, can tip into rigidity and overreach — too many plans, too little pruning.

Like every element, Wood is read for balance, not quantity. The question a chart asks is never 'is there a lot of Wood?' but 'is the Wood supported and governed?' — fed enough by Water to grow, cut enough by Metal to keep its shape. That balance, not the raw amount, is what the reading is about.
