Split Definition

Split definition means the defined centers form two separate groups with no channel between them. It's the most common layout — roughly 45% of people. Those who have it often feel something is missing and are drawn to people who close the gap — which is exactly why it matters not to hand those people their decisions.

How it works

The chart has two "islands" of definition: energy flows continuously inside each one, but there's no link between them. For example, the Head and Ajna are joined to each other, while the Throat, G center and Sacral form a separate group. Whatever is missing to connect them is called the bridge.

Simple and wide split

  • Simple (small) split — a single gate closes the gap. One end of a channel is already activated; only its partner gate on the other side is missing. There are often several such options.
  • Wide split — no single gate joins the groups; it takes a whole channel or even more.

With a simple split, the person feels exactly what's missing and recognizes it in others quickly. With a wide split the gap feels less personal: it's easy to see it as "someone else's problem" or to look for someone to blame. At the same time, a wide split makes it possible to watch people and relationships from a distance, as a calm observer.

How it feels

There's often a quiet sense that something is lacking, as if you're not quite in one piece. Information is processed more slowly because the two parts aren't directly connected: decisions ripen over time, after conversations, sometimes only around certain people. Long stretches alone are harder than for single-definition people.

The themes of the bridging gates often turn into a "life mission": it feels as if these qualities must be developed, though they aren't really your own.

Relationships and conditioning

Here the strongest conditioning comes not from the open centers but from the bridging gates. People who carry those gates are drawn to you, and you to them: around them a sense of wholeness appears. That's why partnership matters so much to split definitions.

The risk is handing decisions over to the bridge. When you only feel whole next to a partner, it's easy to start deciding through them and to cling to the relationship. A bridge is energy someone brings, not an answer to how you should live.

Tips

  • Don't rush: decide through your strategy and authority and give yourself time.
  • Before an important decision, spend time among people without being with anyone in particular: a walk, a café, a bookshop. A mix of strangers bridges the gap neutrally.
  • Find your bridging gates and read their descriptions — it helps you see what exactly draws you.
  • Don't deliberately hunt for "the one who completes me": the right people show up when you follow your strategy.

Bridges

Bridging Gates and Connections

A bridging gate is the missing gate that would join two separate groups of defined centers. Bridges explain why we're drawn to certain people and why we feel more whole around them. They're brought by other people, by planetary transits and even by simply being among strangers.
