How to read it

The sky from here

The twelve lines you see don't originate in deep space. They radiate from Earth itself. The zodiac is not a place — it is a point of view. Twelve directions, drawn from where you stand.

The Sun never moves in this diagram. What moves is Earth — and as it orbits, it changes the angle from which we see the Sun projected against the stars behind it. Your Sun sign is not about the Sun's position. It is about Earth's position on the day you were born.

Watch Mercury. It tears through a sign in a matter of weeks. Now watch Jupiter — it barely moves. A planet's sign changes only when Earth's line of sight crosses one of those twelve boundaries. The faster the planet, the more often that happens.

Each colored line connects Earth to a planet and keeps going — straight through the zodiac wheel. Where it lands is the sign. There is no mysticism in the geometry: it is simply the direction you would need to look, on any given night, to find that planet in the sky.
