The Pain, The Panic, And the Punchlines: Life with an Undefined Spleen

There’s a certain irony in being designed for deep awareness… and yet, consistently confused by what’s going on in your own body.

Welcome to the life of an Undefined Splenic Centre Being.

According to Human Design, the Spleen is the oldest awareness centre we have, it’s all about intuition, survival, the immune system, and instinctual fear. In short: it’s your primal “aha” alert system, designed to keep us alive in the face of tigers, falling rocks, and bad Tinder dates.

Except… mine? Undefined. Which means: No consistent signal. No solid instinct. Just a constantly changing sense of maybe danger? Maybe not? Maybe let’s overthink it anyway?

Childhood: Splenically Spoiled

Luckily, I grew up in a house full of Splenically Defined siblings, a Splenic Projector and Generators (splenically defined) with steady energy, strong immune systems, and the kind of built-in survival instinct that could probably win them a season of Survivor without even trying. Their bodies were steady and grounded, like energetic Labrador Retrievers.

They made me feel safe without saying a word. We laughed. We played. They cracked jokes like it was a family talent. And I basked in their effortless security. I laughed a lot. Probably more than I realized at the time. And because I was always surrounded by these energetic bodyguards, I thought I was fearless. I didn’t realize I was borrowing their energy like a kid using someone else’s Netflix login. But I was. And it was amazing!

Enter Adulthood (a.k.a. Splenic Withdrawal)

Then I moved out. Cue the background music of every horror movie ever made, because suddenly, I was alone… and so was my spleen. I started to feel odd things, like someone watching me, or chasing me (spoiler: no one was). I felt unsafe in ways I couldn’t explain. Not mentally, but physically, a low murmur of unease in my body that seemed to come from nowhere and everywhere.

The Splenic Centre governs intuition, instinctual fear, immune system signals, and survival-based awareness. When Defined, it says, “Hey, step to the left.” When Undefined, it says… “Uhhhh, I don’t know, maybe you’re dying?”

Fear

The Undefined Spleen, in its most raw form, amplifies the fear and instability in the environment, and without a Defined Spleen nearby to ground it? It can feel like walking through a haunted house in broad daylight.

Fear’s More Dramatic Cousin: Pain. When Pain Becomes the Main Character

But more than fear, what really hit me was pain. The kind of pain that doesn’t show up on an X-ray. The kind of pain that doesn’t go away with a nap or a massage. It’s deep. Energetic. And it’s very, very real.

The aching. The tension. The invisible pressure in my body that felt like I was carrying other people’s fear, trauma, stress, and their overdue taxes.

This is the reality of an Undefined Splenic Center: we are like sensitivity sponges with legs.
We absorb the unhealthy state of the atmosphere around us, especially pain; then internalize it, amplify it, and try to function like that’s normal. It’s not.

With an Undefined Spleen and no Motor Defined, I’m deeply attuned to the physical and emotional states of my environment. If someone in the room is in pain, I feel it. If the space carries tension, my body mirrors it. And here’s the hammer: I didn’t know any of it wasn’t mine until I started coming back home to myself and discovered Human Design.

My Favourite Splenic Medicine: My Husband

Now, I have a secret weapon: my husband. A Manifesting Generator with a Defined Spleen to the G, a.k.a. my personal grounding station. When I’m in pain, when it’s too much to process, I just sit near him, of course, I ask first, respecting his Sacral Power, or be coddled by him. I don’t need to explain anything. I just… exist in his aura.

Coddle

And slowly, my body exhales. The pain softens. The noise dims. It’s not magic; it’s frequency. His Splenic Definition offers my system the consistent safety it doesn’t naturally produce. (And yes, I married him through recognition and invitation, thanks to my G. Even in the Not-Self era of my life, it showed up at very important occasions.) But that Spleen? Big bonus.

Laughing Through It: My Splenic Siblings

When I think of my siblings now, I realize they weren’t just funny. They were medicine. Being around them helped regulate my body in ways I didn’t have language for at the time. We laughed until we cried. We made silly jokes that still live rent-free in my head. And through it all, their Defined Splenic Centres were holding a field of stability that my body devoured. They didn’t need to fix anything, they just had to be there. They were the original comedy club and trauma buffer all rolled into one.

Laughter

They made me laugh till I couldn’t breathe, but now I realize it wasn’t just the humour, it was their presence. They carried something I didn’t: a consistent relationship with the now.

And when you grow up Undefined in a house full of that? It’s like floating in a big, warm, invisible blanket. I never knew how much they protected me, energetically. (They still don’t. But that’s okay. I’ll just send them this blog.)

The Wisdom in the Undefined Splenic Center

Here’s the beautiful truth no one tells you at first:

Undefined Centres are not flaws. They’re teachers. They’re where we gather our greatest wisdom, once we stop identifying with the noise.

The Undefined Splenic Centre holds the potential to become incredibly wise about:

• Who is truly safe to be around

• What environments are healthy or toxic

• When others aren’t healthy

• How and when to let go of the fear that doesn’t belong to you

• Be aware of your health and what your body needs

• Using Strategy and Authority to decide what is worth holding on to

A Tuning Fork

You become like a tuning fork for wellness and safety, able to sense shifts in the atmosphere with extraordinary precision.

The key is awareness, because if you’re not aware, the pain takes the lead. But if you are aware, your body becomes a wise whisperer of truth.

You’re Not Too Sensitive, You’re Splenically Gifted

If you’re like me, a Projector with an Undefined Spleen, know that you’re not broken, fragile, or too sensitive. You’re designed to feel more, so you can know more. But you’re not meant to carry it all.

You’re here to move through environments, learn from them, and share what you know. You’re not here to stay in painful places just because your body has gotten used to the discomfort. That’s why I teach this work. Through my 12-Week online Living Your Design Course, I help you tune in to what your body’s been trying to say all along.

Let’s decode the noise.
Let’s turn that pain into wisdom.
Let’s get you back to laughing again, because healing doesn’t always have to be heavy.

Your Spleen may be Undefined, but your capacity for wisdom? Absolutely off the charts.
