The 9 Centers in Human Design

Today I wanted to talk about how your ‘type’ is determined in Human Design.

Your type is determined by the combination of your defined and/or undefined centers. Each center represents a specific energy hub. There are currently 9 centers, more about the theme of each one below.

A defined centre is what we call the coloured/filled in parts in your chart. It’s where you have consistent access to that energy. It’s an energy you naturally project out and have the ability to influence others.

An undefined or open center has no colour filled in, because of that you have the ability to take in and amplify the energy from those with defined centers (or transits, think planet placements). You get to sample different expressions of this energy! Which also means it’s an inconsistent energy.

Conditioning in the centers: Open and undefined centers are susceptible to conditioning since it’s an area where you take in and amplify everything from everyone.

Energy is power and sometimes when we don’t discern properly we can succumb under the pressure to act when that energy wasn’t ours to begin with (hence getting out of alignment).

That being said, even defined centers can be conditioned. And by conditioning, it simply means being influenced by those with consistent energy. Which is also not a bad thing! As long as you’re acting on what’s aligned to YOU. That’s why Human Design emphasizes the importance of following your strategy and authority.

As mentioned above, each center represents an energy hub.

Someone who has a center defined vs someone who has the same center undefined means they will experience that energy differently. And add to the equation the rest of your design elements such as type, definition, profile, cross angle, channels etc it becomes a whole other combo! And even if you have a very similar ‘combo’ than someone else, the way you express it and the conditioning you’ve been through will be entirely different.

Root center⬆️

I only have the heart and spleen centers defined. Which means I take in and amplify energy from all the other undefined centers. It’s not a bad thing! We’re all influenced by each other’s energy all the time.

But as mentioned in my previous post, discerning which energy is mine plus which ones I should respond and act on has been pivotal. Am I doing something because it feels right for me or because I’m influenced by someone’s else energy/conditioning? That’s when your strategy and authority can help you discern and align.

Which centres do you have defined? Which do you have undefined? There are cases where all could be defined and all undefined as well.
