Aspect
A meaningful angle between two planets. It tells you whether those two parts of you cooperate or clash.
Measure the angle between two planets around the circle. Certain angles — 0°, 60°, 90°, 120° and 180° — are aspects, and they link the planets' meanings.
Flowing aspects (trines and sextiles) make things easy. Tense ones (squares and oppositions) create friction — which is often where growth and drive come from.
On Horozy's charts, flowing aspects are drawn as solid or dotted blue lines and tense ones as dashed red lines.
