Guide
How compatibility is evaluated
Compatibility is strongest when one quick score is supported by emotional fit, communication rhythm, attraction style, and long-term context.
What is compared
Score logic
Depth
Emotional compatibility
Moon signs, Moon aspects, Nakshatra context, and daily care patterns show how safe and understood the bond may feel.
Communication
Mercury, element balance, pacing, conflict style, and repair habits matter more than a single attraction score.
Attraction
Venus, Mars, chemistry indicators, and mutual responsiveness describe desire more clearly than Sun signs alone.
Long-term potential
Shared values, seventh-house themes, timing cycles, family expectations, and real behavior keep the reading practical.
