An Introduction to the Five Elements — The Principle of Generation and Control
About 6 min read
The Five Elements (五行) are the backbone of Eastern thought. Saju, feng shui, traditional medicine — even the days of the week, directions, and colors — are all explained through the relationships of these five energies. Understand the Five Elements and you'll see that many kinds of fortune-telling are in fact connected by a single language.
What the five energies are
The Five Elements are Wood (木), Fire (火), Earth (土), Metal (金), and Water (水). These are not mere materials but symbols of nature's five 'qualities of movement.' Wood means the reaching that grows upward; Fire, the radiance that blazes upward; Earth, the stability that receives at the center; Metal, the convergence that gathers inward; and Water, the condensation that flows downward and stores. In seasons they correspond to Wood = spring, Fire = summer, Metal = autumn, Water = winter, and Earth = the turn between seasons.
Generation — the cycle that gives life
Generation (相生) is the relationship in which one energy gives birth to the next. Wood burns and feeds Fire (Wood generates Fire); Fire burns out into ash and makes Earth (Fire generates Earth); metal is born within the earth (Earth generates Metal); water beads on the surface of metal (Metal generates Water); and water again nourishes Wood (Water generates Wood). In this way the five energies form an endless circle. In Saju, the energy that gives birth to you is read as the seat of mother, learning, and benefactors.
Control — the check that governs
Control (相剋) is the relationship in which one energy restrains and governs another. Wood draws up and presses the earth's nutrients (Wood controls Earth); Earth dams water (Earth controls Water); Water puts out Fire (Water controls Fire); Fire melts Metal (Fire controls Metal); and Metal cuts Wood (Metal controls Wood). Control is not purely bad — it is the essential check that presses down excess and keeps balance. With only generation, energy flows without restraint; it takes control for order to arise.
The four relationships of each element
Put generation and control together and each of the five elements holds relationships in four directions. Wood (木) draws strength from Water (水), gives birth to Fire (火), restrains Earth (土) and is governed by Metal (金). Fire (火) draws strength from Wood (木), gives birth to Earth (土), restrains Metal (金) and is governed by Water (水). Earth (土) draws strength from Fire (火), gives birth to Metal (金), restrains Water (水) and is governed by Wood (木). Metal (金) draws strength from Earth (土), gives birth to Water (水), restrains Wood (木) and is governed by Fire (火). Water (水) draws strength from Metal (金), gives birth to Wood (木), restrains Fire (火) and is governed by Earth (土). The ten gods of Saju are these four relationships plus the element that matches your own, each split once more into yin and yang.
Balance is the key
The aim of reading the Five Elements is not 'what is good and what is bad' but 'what is excessive and what is lacking.' If a particular energy is far too strong, it needs a controlling element to restrain it or a generating one to drain it off; if it is too weak, the energy that gives birth to it becomes the remedy. Working out which element your Saju needs filled and choosing colors, directions, and habits in that direction is precisely this principle of balance carried into everyday life, though not every element you lack is one to fill, as the 1988 chart below shows.
Trying it on one chart — noon, August 10, 1988
The chart of someone born at 12 noon on August 10, 1988, is 戊辰·庚申·丁酉·丙午, and the Day Master is 丁, yin fire (陰火), often likened to a candle flame. Weighing the elements gives 火 33.8%·金 31.7%·土 26.7%·水 4.2%·木 3.8%, so Fire, the Day Master's own element, looks the largest, yet the verdict is weak (身弱). The element weights include the Day Master 丁 itself, but strong or weak is measured by how much everything other than the Day Master supports it, and that supporting share comes to only 24%. Being born in the autumn 申 month, the chart did not gain the season's support, and the Earth that Fire produces and the Metal that Fire restrains drew away much of its strength. The first thing to remember when looking at elemental balance is that the element with the biggest number is not necessarily on your side.
Not every missing element should be filled
In this chart the elements below 5% are two: Wood (木) and Water (水). People often say a missing element should be filled, but this site first asks whether that element would correct the chart's current tilt or make it steeper. Wood (木) revives the weak 丁, so it becomes the yongsin (用神), and the site recommends filling it. Water (水), on the other hand, is the officer (官星) that presses on 丁, so in a weak chart this site does not recommend filling it even though it is scarce, although schools of gwanin-sangsaeng (官印相生), which see the officer feeding the yongsin Wood and so helping the Day Master in the end, may judge it differently. From the same diagnosis of scarcity, the prescription can go in opposite directions depending on the role that element plays in the chart.
The Five Elements extend to color, direction, and season
The Five Elements also expand into sensory symbols. In color they correspond to Wood = blue-green, Fire = red, Earth = yellow, Metal = white, Water = black; in direction they are assigned Wood = east, Fire = south, Earth = center, Metal = west, Water = north (though for Earth's lucky direction this site points not to the center but to 艮 or 坤, as explained below). So once you know the element that benefits you, it naturally follows which colors of clothing and accessories suit you and which direction is favorable. The auspicious directions and lucky colors of feng shui also come, in the end, from these elemental assignments. Five-element face reading uses the same correspondences. A long, slender Wood face, a Fire face narrow at the forehead and broad below, an Earth face broad all the way from forehead to jaw — the shape itself is matched to an element to read innate temperament.
The Great Plan of the Shangshu and the numbers of the Hetu
The first text to set out the five elements as a system is the Great Plan (洪範) chapter of the Shangshu (尙書, the Book of Documents). It lists them in the order of first Water (水), second Fire (火), third Wood (木), fourth Metal (金) and fifth Earth (土), and describes their natures: water soaks and descends (潤下), fire flames upward (炎上), wood bends and straightens (曲直), metal yields and changes form (從革), and earth is sown and reaped (稼穡). That order meshes with the numbers of the Hetu (河圖, the River Chart) to give the pairs 水 1·6, 火 2·7, 木 3·8, 金 4·9 and 土 5·10. The lucky numbers this site gives in its zodiac-animal and daily readings use these Hetu pairs too, except that for Metal it avoids 4, which in Korean sounds like the word for death (死), and uses 9.
A common misunderstanding — must all five be present in balance?
It is often said that a good chart has all five elements in similar amounts, but what Myeongni looks at is not the shape of the distribution itself but whether the element the Day Master needs is in its place. An element with zero characters can still be hidden in the branches, so the Wood that had no character at all in the 1988 chart above still registers 3.8% in strength. Directions are also widely misunderstood: among the five directions (五方), Earth (土) sits at the center, so there is no actual way to face it. That is why this site gives Earth's lucky direction as 艮 (northeast) and 坤 (southwest), the two trigrams that belong to Earth in the Later Heaven arrangement.
The Five Elements are the key that threads Saju, feng shui, traditional medicine, and name analysis into one. Once you understand this cycle, you'll see that the readings of various fortune systems are not different stories but different faces of the same principle.
