§ Synastry
Two charts.
One reading.
Sun-sign matches are surface. Synastry compares every planet in both charts and reports the real aspects — what creates chemistry, what creates friction, and whether the soul connection has staying power.

What is a synastry chart?
Synastry is the astrological technique of placing two birth charts side by side and reading the aspects — the angular relationships — between every planet in chart A and every planet in chart B. Where sun-sign compatibility says "Aries and Libra are opposites," synastry says "your Mars conjuncts their Venus by 2 degrees, and your Moon squares their Saturn by 4 — here's exactly what that means."
The aspects that matter most
- Sun-Moon contacts — the classic soulmate signature
- Venus-Mars contacts — chemistry, attraction, the physical spark
- Saturn contacts — karmic weight, lessons, longevity
- Moon-Moon contacts — emotional rhythm match
