While synastry compares two individual charts, a composite chart blends them into one chart that represents the relationship itself. It's like the relationship has its own birth chart, its own personality, its own purpose.
**What a composite chart shows:**
— The nature and purpose of the relationship
— The strengths and challenges you face together
— The overall vibe/energy of the partnership
— What you're here to learn or build together
