HeadThe nine centersHuman Design

The nine centres are Human Design's nine functional zones. The head is the topmost, and its function is pressure — not inspiration, pressure: the push of 'there is something I haven't worked out'. It pushes downward, to ask the next centre.

Filled means that pressure is yours and constant. Open means it comes in from other people and gets amplified, which is why an open head can spend a whole night on somebody else's question.

Running well, this pressure is where all enquiry starts: without it nobody would want to understand anything. Blocked, it becomes an endless loop, because pressure demands resolution and the world is full of things that won't resolve in a lifetime. The practical handling isn't thinking faster. It's writing the question down — once written, you find that fewer of them needed answering today than you assumed.
