The Solar Plexus in Human Design: emotions, waves and truth over time

What does the Solar Plexus Centre do?

A defined Solar Plexus produces its own wave: hope and pain, expectation and disappointment, passion and flatness. This movement is chemical and does not need an external trigger. There is no neutral point at which you feel something 'truly'; there is only the wave as a whole.

That is why the essence of Emotional (Solar Plexus) Authority is: wait. Not because you are uncertain, but because clarity only emerges over time. What seemed fantastic at a peak and impossible in a low becomes a calm yes or no after a few days.

As a motor, the Solar Plexus also provides energy. Emotional pressure can take people a very long way, but it is a fluctuating fuel: phases of doing a lot alternate with phases when you get very little done.

• Type of centre: Motor and awareness centre.
• Gates in this centre: 6, 37, 22, 36, 30, 55, 49.
• Around 50 per cent of people have a defined Solar Plexus.

Defined Solar Plexus Centre: what does it mean?

With a defined Solar Plexus, your feelings are deep and changeable. Your mood can shift for no apparent reason, and that is normal. The mistake many people make is trying to explain the wave: you look for a reason outside yourself and always manage to find one, which then creates unnecessary drama.

There are different kinds of waves. Some rise gradually and drop suddenly; others stay flat for a long time and then spike. Which type you have depends on the gates that define your Solar Plexus, but the principle remains the same: no truth in the moment.

Emotional people also bring depth to relationships, art and care. The wave is not a flaw you need to flatten out; it is an awareness that works more slowly than the rest of your system.

• Your mood moves in waves without an external cause.
• Important decisions take days to weeks, not minutes.
• At a peak, you promise too much; in a low, you reject things too quickly.
• Calm after the wave is your signal of clarity.

Open or undefined Solar Plexus Centre

With an open Solar Plexus, you absorb other people's emotions and amplify them. If you walk into a room where there is tension, you feel it more strongly than the people causing it. If you go for a walk with someone who is cheerful, you become exuberant.

The Not-Self pattern is conflict avoidance. Because other people's anger or disappointment hits you so hard, you start swallowing the truth, soothing things over, crossing your own boundaries and putting things right that were not yours to fix. In the long run, this builds up tension that eventually erupts anyway.

Unlike a defined Solar Plexus, an open Solar Plexus does have access to clarity in the moment: your Inner Authority lies elsewhere, for example in the Spleen or the Sacral. That makes it especially important to recognise emotional noise from others as not yours.

• You feel the atmosphere in a room within seconds.
• You avoid confrontation to remove the tension.
• You are exhausted after busy or emotional gatherings.
• Being alone quickly brings you back to your own feelings.

The Not-Self theme: Is this feeling mine, or am I picking it up from someone else?

The way to recognise it is simple: if the feeling disappears when you leave the room, it was not yours. If it stays, there is something of your own that needs attention. For an open Solar Plexus, twenty minutes alone often gives a completely different diagnosis from the conversation itself.

Avoiding conflict solves nothing. Postponing a difficult conversation increases the emotional charge, exactly the opposite of what the open Solar Plexus is seeking.

The wisdom of openness

An open Solar Plexus can be exceptionally good at reading emotions. You know when someone is not feeling good, when a team is tense, when a conversation is really about something else beneath the surface.

That sensitivity becomes useful once you stop taking responsibility for what you feel from others. You can notice it, name it and give it back, without carrying it.

You can start with this today

For a defined Solar Plexus: learn one sentence by heart. 'I'll get back to you on that.' That sentence protects you from nine out of ten decisions you would later have preferred to undo.

For an open Solar Plexus: make time alone a necessity, not a luxury. Schedule an empty block of time after every intense day. Do not make any judgements about a relationship or job in the hours immediately after a confrontation.

• Defined: track your mood for a week and look for the pattern of your wave.
• Defined: do not promise anything at a peak or cancel anything in a low.
• Open: leave the room and reassess what you feel.
• Open: name the tension rather than soothing it away.

This centre in relationships

A defined and an open Solar Plexus together is one of the most common combinations in relationships, and one of the trickiest. One person's wave is picked up by the other and amplified back, causing small irritations to explode.

The way out is not to feel less, but to focus on timing and naming what is happening. 'I'm in my wave; this isn't about you' is one of the most relationship-saving sentences there is.

This centre in children

A child with a defined Solar Plexus has moods that do not always have a cause. Asking what is wrong can then backfire. Staying present without trying to fix anything works better.

A child with an open Solar Plexus feels the tension between parents more keenly than anyone realises and will try to resolve it. Giving this child clarity about what is happening is more reassuring than shielding them.

How does this show up in your chart?

In your bodygraph the Solar Plexus Centre is coloured in when it is defined and white when it is open. A centre becomes defined as soon as a complete channel connects it to another centre; individual gates do not colour in a centre.

Calculate your chart to see which of your nine centres are coloured in. That pattern determines your type, your Inner Authority and which themes in your life are consistent and which you mainly take in from your surroundings.
