What Are Form and Force in Feng Shui According to the Book of Burial? A Thousand Feet Is Force, a Hundred Feet Is Form

What Are Form and Force in Landscape Feng Shui?

In the language of landscape feng shui, form is the mass of earth, the hillock, the sand dune, the specific piece of terrain the eye can see at close range near a planned burial or house site. Force is the path of the mountain vein, the direction a range runs, the winding of rivers at a distance, something the eye must look up to or step far back to perceive. The Inner chapter of the Book of Burial sums up the two with a short line: "千尺為勢，百尺為形", meaning a thousand feet is force, a hundred feet is form. The commentary printed with the text explains: a thousand feet speaks of what is far, the incoming force of one branch of mountains; a hundred feet speaks of what is near, the form taken by one burial site; the forms of mountains and rivers are not really bound to a measure, and the figures are only approximate^[1].

One thing must be said at once about the standing of the source. The Book of Burial is an old feng shui text that tradition attributes to Guo Pu of the Jin dynasty. The Siku quanshu abstract printed at the head of the book says that the text is first seen in the Song dynasty and remarks "必以為出自璞手，則無可徵信": to insist that it came from Guo Pu's own hand is something for which there is no evidence. According to the same abstract, Wu Cheng divided the book into three parts: the Inner chapter for what he judged purest, the Outer chapter for what was half fine and half coarse, and the Miscellaneous chapter for coarse material that deserved to be cut but was kept for the time being; the transmitted edition also carries commentary by later hands^[1]. This article therefore states for each line which chapter it stands in and whether it is main text or commentary.

The Miscellaneous chapter itself opens with a notable line: "占山之法，以势为难，而形次之，方又次之", meaning in the method of reading land, judging force is hardest, judging form is second hardest, judging compass position is third^[1]. This sets an order of priority that today's readers often skip: landscape matters more than position. It is not enough to face the right direction; one must first see whether the land has a vein running to it, whether it has a mass that gathers.

Why Must Form and Force Be Distinguished?

Distinguishing form from force is distinguishing two scales of observation. The commentary under the opening line of the Miscellaneous chapter explains why force is hardest: "势有隐显", force is sometimes hidden and sometimes visible; the force of the mountains may run in from the east while the form gathers in the west, the force may come from the left while the burial site lies on the right, and there are also false sites that deceive the eye^[1]. That means the near view and the far view can give two different answers, and the reader of land must hold both at once. Seeing a fine mound up close is not enough; one must step back and see whether the range behind runs to it in a favorable way.

It should also be said clearly that this is where the schools disagree. The Siku quanshu abstract quotes Wang Yi, according to whom later practitioners split into two lineages: one, beginning in Min (Fujian), relies on stars and trigrams and uses the eight trigrams and five stars to fix relations of generation and control; the other, from Jiangxi, relies on landscape, tracing where the vein rises and where it stops, and concerns itself with how dragon, site, flanking hills, and water fit together^[1]. The second is what is now usually called the landscape school (hình thế or loan đầu), the first the lý khí school. The commentary in the Miscellaneous chapter of the Book of Burial sides with landscape when it writes "是以形势为上，而方位次之", taking landscape as superior and position as secondary^[1]. This article follows the Book of Burial, that is, the landscape school; readers who follow the lý khí school will have a different order of priority.

What Does "Force Arrives, Form Stops, Qi Gathers" Mean?

The line "force arrives, form stops, qi gathers" compresses a chain of reasoning in the Inner chapter. The text says "夫氣行乎地中，其行也因地之勢，其聚也因勢之止": qi moves within the earth; it moves by following the force of the land and gathers where that force stops. Then comes "勢來形止，是謂全氣，全氣之地，當葬其止": force arriving and form stopping is called complete qi, and in ground of complete qi one buries at the stopping point. At the end of the passage the book cites an older classic: "形止氣蓄，化生萬物，為上地也", where form stops and qi is stored, all things are brought forth, and that is ground of the highest grade^[1].

The same idea appears in the Thanh nang kinh (青囊經), another feng shui text, whose circulating edition is printed with the commentary of Jiang Dahong. Its middle scroll has the line "形止氣蓄，萬物化生", almost identical to the classic cited in the Book of Burial; its lower scroll writes "理寓於氣，氣囿於形": principle lodges in qi, and qi is confined within form^[2]. On that account form is the mould that holds qi: to examine qi one must read form, but form must not be confused with qi.

The Thanh nang kinh goes further, placing the whole matter of form and qi within a frame of heaven and earth: "thiên hữu ngũ tinh, địa hữu ngũ hành, thiên phân tinh tú, địa liệt sơn xuyên, khí hành vu địa, hình lệ vu thiên, nhân hình sát khí, dĩ lập nhân kỷ", heaven has five stars, earth has five phases, heaven divides the constellations, earth arrays rivers and mountains, qi moves within the earth, form clings to heaven, by form one examines qi to establish human order^[2]. This is the language of that discipline, not a conclusion of modern astronomy, and should be read as such.

The Eight Directions and Their Desired Landscape

The Miscellaneous chapter devotes a passage to the eight directions, each demanding a different kind of force and form. The table below reproduces that passage, with approximate meanings:

Source: Book of Burial, Miscellaneous chapter^[1].

What is notable is that the commentary printed right after that passage is itself cautious. The commentator writes: the rivers and mountains of the world have countless shapes, how could there be one fixed principle; why should only mountains facing Qian want to be rising and long, broad, thick, and square; this speaks only in general terms; to insist otherwise would be like carving a mark on a boat to find a dropped sword^[1]. This caution matters more than the table: it shows that the later commentator took the eight lines as a rough statement, not a rigid formula.

What Are Good Forms and Bad Forms According to the Book of Burial?

The Miscellaneous chapter lists a series of forms to distinguish good from bad. This listing is the discipline's own, based on associating shapes with animals and objects and on observational experience, not a tested standard table. Below are the forms stated clearly:

• Form like leaning on a screen, with a hill standing in the middle: the rule is to bury at the stopping point; lords and marquises arise^[1].
• Form like a swallow's nest: burial at the curve, foretelling enfeoffment and titles^[1].
• Form like a tilted rampart, rear mound coming from afar, front response curving back: foretelling the ranks of the three ducal and nine ministerial offices^[1].
• Form like an overturned cauldron (形如覆釜): the main text says the summit brings wealth; the commentary holds instead that this form calls for burial at the foot of the mound and criticizes the habit of burying on the summit^[1].
• Form like an upright cap: lasting prosperity and joy^[1].
• Form like scattered counting rods: a hundred affairs in disorder^[1].
• Form like clothing in disarray: women given to lewdness^[1].
• Form like a bag of ashes: houses and storehouses struck by fire^[1].
• Form like an overturned boat: women ill, men in distress^[1].
• Form like a crosswise chair: descendants cut off^[1].
• Form like a lying sword: execution and coercion^[1].
• Form like an upturned knife: inauspicious, one must flee^[1].

This list must be read with two relaxations supplied by the commentary printed with it. First, the form like a crosswise chair is classed as inauspicious by the main text, but the commentary records that some well-known lineages buried an ancestor in that form and still prospered through letters and examinations, so it cannot yet be discarded because of the word inauspicious^[1]. Second, the form like a lying sword is also classed as inauspicious, but the commentary cites a case of a sword form that still produced nobility^[1]. That is, even within the transmitted book, the conclusions of the main text are softened by the commentator. This is where landscape feng shui should be read as an interpretive tradition with internal debate, not a rigid lookup table.

When Are Force and Form in Harmony or Opposition, and What Makes Them Auspicious or Inauspicious?

One of the key lines of the Miscellaneous chapter is: "势与形顺者吉，势与形逆者凶", when force and form are in harmony it is auspicious, when opposed it is inauspicious; according to the commentary, good force with bad form still allows hope of one day's blessing, while bad force with good form brings disaster before the day is out^[1]. This phrasing shows force weighs more than form. A fine mass of earth whose rear mountain vein runs backward, breaks, or escapes cannot be saved by the beauty in front.

The commentary states the standard of harmony and opposition briefly: both force and form take stopping and resting as harmony, and flying and running, shaking and pushing as opposition^[1]. Under the main-text line "形类百动，葬者非宜" (a form that resembles something in motion is not fit for burial), the commentary writes: only a form resting like a corpse lying still, unmoving, can hold a burial; if it is still unsettled it cannot be used; not only the host mountain, but anything seen flying, perching, swaying, pushing, indifferent to oneself must be avoided^[1]. Put in today's terms: the criteria of stability and gathering are placed before the criterion of beauty.

Which Forces Does the Miscellaneous Chapter Call Auspicious or Inauspicious?

Before the list of forms, the Miscellaneous chapter names seven forces, four auspicious and then three inauspicious, notable because they describe movement rather than mass:

• Force like ten thousand horses descending from heaven: the burial place of a royal^[1].
• Force like great waves, mountains layered: the burial place of one with a thousand chariots^[1].
• Force like a descending dragon, water wrapping, clouds following: the rank of the three ducal offices^[1].
• Force like a storied house: opening a prefecture and founding a state^[1].
• Force like a startled snake, crooked and slanting: loss of house and state^[1].
• Force like spears and lances: death by weapons; the commentary says descendants mostly die violent, untimely deaths^[1].
• Force like water flowing downstream: the living too become ghosts^[1].

All three inauspicious forces are explained by the commentary through the way the mountain vein travels. The startled-snake force is a vein that darts sideways and straight ahead, shrinking back instead of running freely. The spear force is sharp as a spear blade and straight and stiff as a lance shaft. The flowing-water force is a vein that pours straight down with no sign of stopping; the commentary says burial there means early death and death far from home^[1]. What separates auspicious from inauspicious force is therefore not whether the mountains are high or low, but whether the vein moves supply and comes to a stop.

Water and the Force of Water

The Outer chapter of the Book of Burial gives many lines to water, and here the relation between force and form appears most clearly. According to the commentary, where water moves and bends there must be a place where it gathers, a place where it stops, though not necessarily right in front of the burial; a single stretch of water like that can be called good^[1]. Water that lingers and clings, as if unwilling to leave, as if turning back to look and wanting to stay, is beautiful water force^[1]. Water arriving with no visible source, water leaving with no visible course, is water force concealed and closed^[1].

A classic cited in the Book of Burial says: "山来水回，贵寿而财", mountains coming and water returning means nobility, longevity, and wealth; mountains coming means the mountains gather, water returning means the streams meet around^[1]. Conversely, "山囚水流，虏王灭候", mountains imprisoned and water flowing away: kings are taken captive and marquises destroyed^[1]. The commentary explains: mountains imprisoned means the bright hall is cramped and not broad, water flowing away means the origin spirit runs straight without bending^[1].

Three Good Conditions and Six Bad Conditions

The end of the Miscellaneous chapter gives three good and six bad conditions of burial, of which only the third good condition belongs to landscape proper:

• First good condition: burial at the right time, in accord with year, month, day, and hour, good spirits receiving, evil spirits avoiding^[1].
• Second good condition: yin and yang in harmony, with four of the five colours of earth present; the commentary in the Outer chapter explains that "four" is said because black is not wanted^[1].
• Third good condition: skill of eye and sufficiency of effort, following the whole and avoiding the flawed, raising and lowering correctly^[1].

The six bad conditions are: yin and yang misaligned; year and season at odds; small strength with great plans; relying on fortune and power; overreaching above and stinting below; and disturbances and strange signs arising^[1]. Notably, several of these are not about land but about people. According to the commentary, "small strength with great plans" is a person of thin fortune scheming for land fit for kings and marquises; "relying on fortune and power" is a wealthy house that assumes it will always be as it is today and so does not exert itself to find proper ground for its parents; the sixth is having good ground and yet delaying the burial until troubles multiply^[1]. Under the fourth, the commentary cites the Records of Wei: Guan Lu passed the tomb of Guanqiu Jian (written 毋丘俭 in the book), General Who Subdues the East, and sighed that though the pines and cypresses were lush and the stele fine, there would be no descendants to keep them, that the four dangers were all present, and that by the rules the clan should be exterminated; the book records that it later came to pass^[1]. This is a story the commentary cites to illustrate its argument, not evidence that the method works.
