The Bagua.

You are standing in the middle of your living room with a printed floor plan in one hand and your phone's compass app open in the other, unsure whether to trust the little blue arrow or the front door. The real first question is not which corner is which. It is which way to even hold the paper. Get that wrong and every sector you name after it is wrong too, all the way through the walk.

Two arrangements, one used for living homes

The word breaks into two pieces. Ba, "eight", is the count. Gua, "trigram", is the unit being counted. A trigram is a stack of three lines, each one either solid or broken, and together they picture one quality of motion in the world. Eight trigrams give eight stable combinations of those lines, and therefore eight directions of attention you can pay to a space. The Bagua divides any bounded space into eight sectors plus a centre on that basis, and there are two historical arrangements of the eight trigrams behind it.

Xian Tian Ba Gua, "Early Heaven", is the older arrangement. It pictures the world before things took shape, and historically it was used for protection work and funerary feng shui, not for designing the rooms you actually live in. Hou Tian Ba Gua, "Later Heaven", is the everyday arrangement. It pictures the world after things have taken shape: the world of houses, kitchens, beds, and front doors. This is the arrangement this guide uses throughout, and it is the one behind everything below.

Why a map layer, not a magic overlay

This part matters more than the etymology. The Bagua tells you where to look. It works as a map over the room, rather than charging a corner or activating a wall. You stand in your home with a floor plan in your hand. You decide how to orient the map, which is the whole question this page answers. Then you walk the home sector by sector. You ask what is there. You ask what is missing. You ask what the room is being used for. You ask whether the room's function sits comfortably with the life area the sector points at.

That is the work: noticing. The Bagua is a structured noticing device, a focusing tool. It gives the eye somewhere to land in a room that would otherwise feel like a blur of furniture and surfaces. The tradition associates each sector with a life area for a reason; the eight directions, the five elements, and the rhythms of a household have been mapped against each other for a long time, and the labels turn out to be useful. Useful, not magical. The Bagua is the map. The room is the territory.

Pick a method before anything else lines up

There are two ways to lay the Bagua over a home, and the choice is the single largest practical divide in feng shui. One method trusts the compass. The other trusts the front door. They produce different maps of the same house, and you have to pick one before anything else lines up.

The compass method

This is the Classical approach. It is what Form School, Compass School, and Flying Stars (a directional timing system) all use. It treats your home as a unique alignment with the real compass directions of the earth.

The procedure is short. Stand in the centre of the home. Face the front door. Take a compass bearing. Then rotate the Bagua so its directions match the real-world directions of the building: south sits where south is, north sits where north is, and the map and the world agree. The reading is the load-bearing step. Without a compass reading, nothing else lines up. The bearing is what ties the rest of the tradition to your specific home: the elements, the trigrams, your Kua number, all of it keys off the reading.

A phone compass will get you started, and a simple handheld one is enough for the bearing. It is worth pausing on how small that instrument has become. The compass sitting in your coat pocket is doing the same job, on the same principle, that a ship's navigator once did with a brass housing and a floating needle to find land with nothing else in view.

The front-door method

This is the BTB approach, Black Sect Tantric Buddhism, from Lin Yun's Black Sect tradition. It treats every home consistently and works without a compass.

The Bagua is anchored to the front door, not to the directions of the earth. Stand at the threshold facing in. The map drops over the room from where you are looking. Knowledge sits at the near-left. Career at the near-centre. Helpful People at the near-right. Wealth sits at the far-left. Fame at the far-centre. Relationships at the far-right. The same nine sectors, the same life areas, but anchored to your entry instead of to magnetic north.

The advantage is portability. Any home, any room, any rental, no bearing required. The trade-off is that the map no longer corresponds to the actual directional logic the Classical schools work with. You are choosing a different lineage, not a shortcut.

How to pick one

If you can take a compass bearing and want the tradition the rest of this guide teaches, use the compass method. It belongs to Compass School, and almost everything else in this cluster assumes it. If you are renting, traveling, or want a simpler first pass, the front-door method does real work. Many readers find it still trains the eye. It is a different tool, a real one, with its own job.

Pick one. Stick with it. Switching methods mid-walk is the most common beginner mistake, and the fastest way to end up with a map that contradicts itself. If you start with the front-door method and later want the compass method, run the whole reading again from scratch.

What both methods agree on

Both methods place a life area in every sector of the home. Both methods ask you to walk the home sector by sector. Both rest on the same nine life areas and the same trigram set. The two methods disagree on placement. They agree on intent. Compass or door. One Bagua. One walk.

Whichever you choose, the map only ever does half the job. It tells you where to stand and which question to ask while you are standing there. It does not tell you what you will find, and it does not do the noticing for you. That part is the walk itself, room by room, with the floor plan in one hand and a clear eye on what is actually in each corner.

Where to go next

Ten seconds: find your personal direction with the Kua calculator. For the full walk through what the map actually is and the nine sectors named one by one, south to fame, southwest to love, all the way round to the centre, the feng shui bagua map is the page to read next. If your floor plan is not a clean rectangle, an L-shape, a multi-storey home, or a single studio, missing corners and irregular homes covers the cases the tool was never drawn for.
