How to Read Your Bodygraph

Your bodygraph is the map at the heart of Human Design — the colourful body-shaped diagram you get when you enter your birth date, time, and place. At first glance it looks like a circuit board crossed with an anatomy chart, and that's not far off: it shows how energy flows (or doesn't) through you. The good news is you don't have to decode all of it at once. There's a natural order to follow, and the first few steps already give you most of what matters.

This page is your guided tour. We'll name every part of the bodygraph, then walk through the exact sequence to read it in — from the big picture down to the fine detail.

The three building blocks#

Everything in your chart is built from just three things. Learn these and the rest falls into place.

• Centers — the nine shapes (triangles and squares) on the bodygraph. Each governs a kind of energy: thinking, communicating, identity, willpower, life-force, emotions, intuition, and so on.
• Gates — the 64 numbered points sitting on the edges of the centers. Each gate is one of the 64 I Ching hexagrams and adds a specific, granular flavour to a center.
• Channels — the lines that connect two centers. A channel is made of two gates, one at each end. When both gates are activated in your chart, the whole line lights up and a permanent energy pathway forms between those two centers.

That's the whole machine. Your type, strategy, authority, and profile aren't extra parts — they're derived from how these centers, gates, and channels combine.

How a channel forms#

A channel only counts when both of its gates are switched on — one at each end. With just one gate active, only that gate's half of the line colours in (a hanging gate), and the centers it would join stay open. The moment the second gate joins it, the whole channel lights up and both centers at its ends become defined.

Only gate 17Half the channel colours in. It isn't complete, so no center is defined yet.

Only gate 62The other gate fills the other half — still half a channel, still no definition.

Both gatesThe full channel forms and both centers it joins (Ajna and Throat) become defined.

Defined vs. open — the most important distinction#

Look at the colours. Some centers are colored in (defined); others are white (open or undefined). This single distinction drives almost everything.

DefinedColoured in — a consistent, always-on energy you can rely on.

OpenWhite — variable and receptive; you take in and amplify others here.

	Defined center	Open (undefined) center
Colour	Filled in	White
Energy	Consistent and reliable — it's always "on" and works the same way	Variable — you take it in from others and the environment, amplifying it
Feels like	A fixed trait you can count on in yourself	A place of sensitivity, learning, and wisdom (but also conditioning)

A center becomes defined when at least one full channel running into it is colored. Defined centers are who you consistently are. Open centers are where you're impressionable — you feel other people's energy there strongly, which is a gift for wisdom but also where you're most likely to take on conditioning and try to be someone you're not.

Roughly speaking: defined = your steady broadcast; open = your antenna.

Personality and Design — the two colours#

Look again and you'll see the colours come in two inks: black and red. That's because every chart is calculated twice and the two layers are laid on top of each other:

• Personality (black) is your conscious self, calculated for your exact birth moment — the "you" you recognise and would describe.
• Design (red) is your unconscious, body-based self, calculated for a moment about three months earlier — gifts others often notice in you before you do.

A gate, channel, or center can be activated by either layer, or by both at once. So the very same channel can light up in three different ways:

All DesignBoth gates come from the unconscious Design layer — drawn in red.

All PersonalityBoth gates come from the conscious Personality layer — drawn in black.

A mixOne gate is Design, the other Personality. The channel still forms.

It doesn't change the outcome: once a channel is complete, it and its centers are defined just the same. The red/black split only tells you whether a trait is conscious or runs below your awareness. For the astronomy behind it, see how a chart is calculated.

The order to read your chart in#

Don't start with the 64 gates. Start at the top of the funnel and work down. Each layer below adds detail to the one above it.

1. Type — the big picture#

Your type is the first and most important thing to know. It's determined entirely by which centers and channels are defined — specifically by your aura (how your energy meets the world) and whether you carry consistent life-force energy. There are five: Manifestor, Generator, Manifesting Generator, Projector, and Reflector. Knowing your type tells you the kind of energy you're working with.

2. Strategy — how to engage#

Each type has a strategy: the simplest, most reliable way to move through life with less resistance. A Generator is here to respond; a Projector waits for the invitation; a Manifestor informs before acting. Strategy answers how should I approach opportunities?

3. Authority — how to decide#

Your authority is your built-in decision-making compass: the signal inside your body to trust when you're making a real choice. It comes straight from which centers are defined — emotional, splenic, sacral, and so on. Where strategy is the how, authority is the what to trust in the moment. Together, strategy + authority is the practical core of Human Design and where almost all the change happens.

4. Profile — the role you play#

Your profile (two numbers like 1/3 or 5/1) describes the character you move through life as — the costume your type wears. It comes from the lines of your Sun and Earth placements and colours how your strategy and authority show up day to day.

5. Centers — your fixed and open energies#

Now zoom into the nine centers. Note which are defined (consistent strengths) and which are open (sensitivity, wisdom, and where you get conditioned). This is the layer that tells you where you're reliable and where you're absorbing the world.

6. Channels and gates — the fine detail#

Finally, the channels and gates add texture: specific gifts, talents, and themes wired into you. These are a deep, rewarding study you can explore over months and years — but they make far more sense once the layers above are in place.

A worked example#

Say your chart looks like the sample above, with the Ajna, Throat, G, Heart, and Spleen defined and the Sacral open. Here's how the order pays off:

1. Type — an undefined Sacral with no motor wired to the Throat points to a Projector.
2. Strategy — wait for the invitation for the big things.
3. Authority — with the Spleen defined and the Solar Plexus open, this is likely splenic authority: trust the quiet, in-the-moment hit.
4. Profile — read the two profile numbers to see the character driving it all.
5. Centers — defined Ajna, Throat, G, Heart, Spleen are steady strengths; the open Sacral is where energy must be managed and not overspent.
6. Channels/gates — the specific colored channels (here, between those defined centers) name the exact gifts at play.

Notice how each step builds on the last. By the time you reach the gates, you already understand the person.

How to use this in practice#

• Don't try to memorise everything. Layer 1 — type, strategy, authority, and your defined vs. open centers — gives you the vast majority of the practical value.
• Experiment, don't believe. Human Design is meant to be lived and tested. Try running your strategy and authority for a few weeks and watch what changes.
• Come back for the detail. The gates and channels are a lifelong study. They reward patience, and they land best once the foundation is solid.

Start with your type, then pair it with your strategy and authority — that's the doorway into the whole system.
