The Five Elements

Wood, Fire, Earth, Metal, Water. Not substances but phases, each producing the next and restraining the one beyond. Where the system came from and how old it is, the two cycles the tradition uses and the two it leaves to medicine, the vocabulary it gives shape, colour, material and direction, the hills it was first read in, how a room is diagnosed before anything is added, and what the colour research does and does not support.

Earth

Fig. 01 A room read for its phases. The wooden table is Wood, the plaster, the clay vase and the stone floor are Earth, the lamp is Fire; the phases are the materials a room is made of.

The Chinese term is wu xing, five goings or five phases, and the usual translation, “elements,” misleads. Wood, Fire, Earth, Metal and Water are not what things are made of. They are five ways that things change: growing, radiating, settling, contracting and flowing. A tree is Wood; so is a tall window, a spring morning and the impulse to begin something. This page says where the five came from, how the tradition sets them in motion, what they name in a room, and what a reader can and cannot do with them.

Phases, not substances

The system is older than feng shui and wider than it. The five are listed in the Great Plan chapter of the Book of Documents, one of the oldest Chinese texts, as water, fire, wood, metal and earth, each with what it does: water soaks and descends, fire blazes and ascends, wood bends and straightens, metal follows and changes, earth takes seed and gives crop. In the third century before the common era the philosopher Zou Yan made them a theory of history, each dynasty ruling under a phase and giving way to the phase that conquers it, and the Han scholars who followed built the correspondences that feng shui inherited: seasons, directions, colours, tastes, organs, planets, notes of the scale, and the animals of the compass. Needham’s history of Chinese scientific thought traces the growth; Feuchtwang shows the system as practitioners use it, a table of correspondences read in every direction at once.

Feng shui takes the subset that concerns space. Each phase has a direction, Wood east, Fire south, Earth centre, Metal west, Water north; a shape; a family of colours; a family of materials; and a season, and the practitioner reads a room for which phases are present, which dominate and which are absent. Chinese medicine takes another subset, the organs and the pulses, and cooking another, the tastes; the system is the same and the reading is different, which is why a feng shui manual and a medical text can use the same diagram for different ends.

What makes the system more than a list is that the five are in motion. Each produces the next and is produced by the one before; each restrains one and is restrained by another. The two cycles are the whole method.

The two cycles

Fig. Round the ring, each element produces the next: Wood feeds Fire, Fire makes Earth, Earth yields Metal, Metal condenses Water, Water nourishes Wood. Across the star, each restrains the one two steps on.

The generating cycle, sheng, runs clockwise round the ring. Water nourishes Wood; Wood feeds Fire; Fire leaves ash, which is Earth; Earth yields ore, which is Metal; Metal condenses moisture on its surface, which is Water. The images are agricultural and metallurgical and they are meant literally as much as symbolically: the cycle is a farmer’s year and a founder’s workshop.

The controlling cycle, ke, crosses the ring as a five-pointed star. Wood breaks Earth, roots through soil; Earth dams Water; Water quenches Fire; Fire melts Metal; Metal cuts Wood. Where the generating cycle is used to support a phase that is wanted, the controlling cycle is used to reduce one that is excessive. Medicine adds two more, the overacting and the insulting cycles, in which a phase controls too strongly or turns on its controller; feng shui does without them, and a reader who meets them in a manual has met a physician’s diagram.

Where the phases were first read

The five shapes were read in hills before they were read in furniture. The Form School classifies mountains by their outline, and the Han Long Jing, the Tang treatise on reading landform, gives the five their forms: a hill that rises tall to a narrow top is Wood, a pointed peak is Fire, a flat-topped hill with square shoulders is Earth, a rounded dome is Metal, and a low, many-crested ridge is Water. The reading matters for a site because the phases interact: a Fire peak behind a house threatens it, an Earth table in front of it steadies it, a Metal dome shelters it. Indoors the same eye reads a room’s furniture by outline, and the shapes in the table below are the hill shapes brought inside.

Fig. 01 The five phases as the Form School sees them in hills. A tall hill that rises to a narrow top is Wood; a pointed peak is Fire; a flat-topped, square-shouldered hill is Earth; a rounded dome is Metal; a low, irregular ridge with many crests is Water. The classification is the Han Long Jing’s and every later treatise repeats it, and it is the origin of the shapes the vocabulary gives to furniture and rooms: the tall bookcase that is Wood, the pointed roof that is Fire, the low square table that is Earth, the arch that is Metal, the wavy line that is Water. The shapes are read for what they do to a site: a Fire peak behind a house is a threat, a Metal dome is shelter, an Earth table is the ideal hill in front. Indoors the same eye reads a room’s furniture by outline, which is the practical content of the phases and the reason a designer can use them without the cosmology.

A vocabulary for rooms

Phase	Motion	Shape	Colours	Season	In a room
Wood	Rising, expanding	Tall, columnar, rectangular	Green, teal	Spring	Timber, plants, height, fibres
Fire	Radiating	Triangular, pointed	Red, orange, strong pink	Summer	Light, hearth, lamps, warmth
Earth	Settling, holding	Square, flat, low	Ochre, sand, terracotta	Late summer	Clay, plaster, stone, weight
Metal	Contracting	Round, spherical, arched	White, grey, metallic	Autumn	Steel, brass, white walls, edges
Water	Flowing, descending	Wavy, irregular	Black, deep blue	Winter	Glass, mirrors, darkness, curves

Read down the “in a room” column and you have most of what the vocabulary does in practice. A white, hard-surfaced, round-lit contemporary interior is heavily Metal, whether or not its designer intended it. A room of low timber furniture and green textiles is Wood and Earth. A room of glass, chrome and black leather is Metal and Water, and it is cold in the tradition’s reading and in the ordinary one. Neither is wrong; the system only says what is there, and then says what would balance it.

Fig. 02 The five phases on one sheet. Each column is a phase: the shape the tradition gives it, three steps of its colour, and the motion, the materials, the directions and the season assigned to it. The columns are the site’s five element colours, which are used everywhere a phase is named. A reference, not a rule. A room is rarely one phase; the sheet says what a room is made of when it leans one way, and what to add when the cycle on this page says it is short of another.

The same vocabulary, drawn. Each column is one phase: its shape, three steps of its colour, and the materials, directions and season the tradition assigns to it. Read across and the phases are five moods a room can have; read down and each is a shopping list. The drawing is a reference, not a rule: nothing in it says a room must be one phase, only what a room is made of when it is.

Two rooms, read

The method is easiest to see in use. A flat as the estate agent left it: white walls, a grey floor, a glass table, a white sofa, spotlights in the ceiling, a chrome lamp. Everything in it is Metal, with Water in the glass and the reflections; there is no Earth to stand on, no Wood to rise, no Fire to warm. The reading says what a visitor feels, that the room is clean and cold and nobody has sat in it, and the cycles say what to do: Fire melts Metal, so a warm lamp and one red or orange thing; Earth to give weight, so a heavy rug, a wooden table, a wall in a warm neutral; Wood to lift, so one tall plant. Three objects, chosen by the cycle, and the room is a room.

The opposite flat: an old parlour with a brown carpet, brown furniture, a low ceiling, heavy curtains and every surface at the same height. It is Earth and Wood with nothing else, and it feels stuck, which is the tradition’s word and the visitor’s. Wood controls Earth, so one tall thing, a column of shelves or a plant that reaches the ceiling; Metal to give edge and light, so a mirror, a white wall, a lamp with a hard shade; and the curtains opened, which is Fire. The system did not tell the reader anything a good decorator would not have said. It told them in an order, and gave them a reason to stop at three.

Fig. 03 The two rooms the essay reads, with the count under each. On the left the flat as the agent left it: a white sofa, a glass table, a grey floor, spotlights and a chrome lamp, which is Metal five times over with Water in the glass and the reflections, and nothing else at all — no Earth to stand on, no Wood to rise, no Fire to warm. The three additions are chosen by the cycles, not by taste: Fire melts Metal, so a warm lamp and one red thing; Earth gives weight, so a heavy rug and a wooden table; Wood lifts, so one tall plant. On the right the opposite flat, an old parlour of brown carpet, brown furniture and heavy curtains, which is Earth and Wood and feels stuck: Wood controls Earth, so one tall column of shelves; Metal gives edge and light, so a mirror, a white wall and a hard-shaded lamp; and the curtains opened, which is Fire. The strip is the whole method: five cells, filled where the room holds the phase and an open ring where it does not, and the absences are what the reading is for. Neither list of three says anything a good decorator would not have said. The system says it in an order, and gives a reason to stop at three. The low ceiling of the second room and the height of its surfaces cannot be drawn in plan and are in the essay instead.

Using it

The practical use of the phases is corrective and modest. A room that feels restless, too much Fire, strong light, strong colour, screens, is steadied with Earth, the controlling neighbour: a heavy rug, a low table, a wall in a warm neutral. A room that feels stuck, too much Earth, everything low, matte and the same height, is lifted with Wood, which controls it: one tall thing, a plant, a column of shelves. A room that feels clinical, too much Metal, is warmed with Fire, which melts it, one warm lamp, one red object, and weighted with Earth. A room that feels loud, too much Wood, is pruned with Metal, an edge, a white surface, a clear space. The correction is always one phase, in one or two objects, chosen by the cycle; the tradition does not want a room of five equal parts, which is a room with no character, but a room with a dominant phase and its balances.

Where the elements meet the compass

Each phase belongs to a direction, and so each sector of the bagua has a phase: Water in the north, Wood in the east and south-east, Fire in the south, Earth in the south-west and north-east, Metal in the west and north-west. The tradition reads this as a reason to furnish a north room with Water’s materials, or to support it with Metal, which generates Water, and the compass schools extend it to the stars of a Flying Star chart, each of which carries a phase to be fed or checked. The site’s own reading is more cautious and more useful: north rooms get cool, even light; furnish them so they do not feel cold, which by the cycle means Earth and Fire, and by the designer’s eye means a rug and a lamp. The element pages take each phase in turn, the colour guide gives the palettes in proportion, and the Explorer shows the five on the ring.
