Solar Plexus Center in Human Design: Emotion Waves
The Solar Plexus center in Human Design is a motor and awareness center on the lower right of the bodygraph, the source of the emotional wave. It holds seven gates (6, 22, 30, 36, 37, 49 and 55) and connects to the Heart, Root, Sacral and Throat.
What the Solar Plexus center is
In plain EnglishOn the lower right of the chart, a triangle holds the emotional wave: moods that build, crest and settle over time.
Treat the word “wave” as a metaphor from a 1987 belief system, with no science behind it. The Solar Plexus is a motor and also an awareness center, the only center with both jobs. It holds seven gates (6, 22, 30, 36, 37, 49 and 55) and touches seven channels, reaching the Heart, the Root, the Sacral and the Throat.
The system says feelings here move like weather: hopeful on Monday, flat on Wednesday, hopeful again by Friday. It does not call any phase wrong. It also says the wave is long, so a mood that lasts three days is normal for a defined center, and the slow rhythm is the reason behind the advice to wait before big decisions.
Defined Solar Plexus center
In plain EnglishA colored Solar Plexus means you run on your own emotional wave, and the wave is the reason you should never decide at the top of it.
On Sunday evening you feel certain about quitting your job. By Tuesday you are less sure, and by Friday you have a more rounded view. That swing is the point. Others may find you steady, then suddenly intense.
Picture a house hunt. The first viewing feels magical, the second feels dull, the third lands in between, and that third reading is the one to trust. The gift is depth and a feel for real clarity when it comes. The trap is two-sided: deciding at a high and regretting it, or sinking into a low and calling it truth. The system’s rule is to sleep on it and wait until the pull settles. Our page on emotional authority covers the decision method.
Undefined (open) Solar Plexus center
In plain EnglishA white Solar Plexus means other people’s moods come through you, and you may feel them as your own.
A coworker storms in and your stomach clenches. A partner is cheerful and you drift into cheer, then wonder why you are exhausted. At a family dinner you sense the tension at the table before anyone says a word.
Open does not mean weak. It means the sensor is wide. The gift is a kind of emotional radar and a talent for smoothing a room. The trap is avoiding conflict by saying yes, or amplifying a mood until it is bigger than it was. Ask: was I feeling this before I walked in? Take a short walk to find out.
Gates of the Solar Plexus center
In plain EnglishSeven gates share the Solar Plexus, and each is a different feeling: friction, openness, desire, crisis, friendship, principle or mood.
- gate 6: friction and boundaries at the start of closeness.
- gate 22: grace and a willingness to be moved by a feeling.
- gate 30: desire, the burning wish for an experience.
- gate 36: crisis that leads to a new experience.
- gate 37: friendship and the unspoken bargains of belonging.
- gate 49: principles, and the point at which you refuse to stay.
- gate 55: mood itself, with its highs and lows.
Each is cross-listed in all 64 gates.
Channels of the Solar Plexus center
In plain EnglishSeven channels run from the Solar Plexus, and the neighbor each reaches shapes how the feeling shows up.
- To the Sacral: channel 6-59 (Intimacy).
- To the Throat: 12-22 (Openness) and 35-36 (Transitoriness).
- To the Root: 19-49 (Synthesis), 30-41 (Recognition) and channel 39-55 (Emoting).
- To the Heart: 37-40 (Community).
A defined channel here is what makes the center colored. Teachers disagree on whether the channel to the Throat makes you voice your mood, with some saying yes and others saying the wave still needs time before speech.
Solar Plexus center in relationships
In plain EnglishIn a relationship the Solar Plexus decides whether feelings are shared in real time or only after the wave has passed.
A defined Solar Plexus partner may need a night before they can say what they felt in an argument. Their partner may read this as avoidance. An open Solar Plexus partner reflects the mood in the room and might leave a fight with no clear idea of what was theirs.
Heart-to-heart talks are where the two setups collide. The practice that works in love is a pause with a promise: “I need until tomorrow, and I will bring it up then.” The other person gets a time, and the wave gets its space.
Solar Plexus center at work
In plain EnglishAt work the Solar Plexus shows up as mood swings in your output, and a rule about when to commit.
With a defined Solar Plexus, you may sound brilliant on Monday and flat on Thursday, with no change in skill. Do not sign a contract or send a resignation at the peak or the dip. Ask for a day on big offers, and write down how you feel at 9 am, noon and 5 pm so you can see the curve.
With an open Solar Plexus, you may be the person who senses the team’s temperature and quietly adjusts it. The trap is being the sponge. Because this is a motor, a Solar Plexus connected to the Throat makes you a person who starts things by speaking. See the Human Design chart tool to check which of the seven channels you hold.

Questions people ask
- What does the Solar Plexus center do in Human Design?
- It carries feelings as a wave that rises and falls over hours, days or weeks. It is both a motor and an awareness center, so it supplies drive and also a way of sensing. The system says clarity comes after the wave, not at its peak.
- What does an undefined Solar Plexus mean?
- It means you have no fixed emotional wave of your own, so you take in other people's moods and may amplify them. You can be calm alone and tense in a tense room. The system suggests asking whose feeling it is before reacting.
- How many gates does the Solar Plexus have?
- Seven: gates 6, 22, 30, 36, 37, 49 and 55. Seven channels touch the center, running to the Sacral, Throat, Root and Heart, so it is a hub for feeling in the lower half of the chart.
- What is emotional authority?
- It is the system's authority for any chart with a defined Solar Plexus, and it ranks first among the seven. The rule is to wait through the wave before a big decision, and to let the feeling settle until you have clarity.
- Is the Solar Plexus a motor center?
- Yes. It is one of four motors, along with the Heart, Sacral and Root. It also acts as an awareness center, which makes it the only center in the chart that is both.
