Composite vs Synastry
Synastry compares two people side by side. Composite calculates midpoints to create a single chart representing the relationship field.
Use synastry for interpersonal dynamics; composite for shared purpose, public identity, and long-term trajectory.
Key Composite Placements
Composite Sun shows central mission. Moon reflects emotional climate. Saturn highlights tests and commitment structure.
Hard aspects are not doom — they show where the relationship matures through effort.
Ethical Use
Charts describe potential, not permission. Healthy relationships still require boundaries, repair skills, and aligned values.
