Synastry and relationship charts

How does Western astrology compare two people?

Where Vedic matching scores the two Moons (Guna Milan), Western synastry lays one chart over the other and reads every aspect between them.

Venus–MarsAttraction and chemistry.
Moon–MoonEmotional rhythm: do your moods and needs fit?
Sun–MoonA classic marriage link: one's identity meets the other's feelings.
Mercury contactsCommunication: do you understand each other easily?
Saturn contactsCommitment and duty, or heaviness and criticism. The "glue" of long relationships.
Node contactsA feeling of fate or familiarity.
House overlaysWhere one person's planets fall in the other's houses: in the 7th (partnership), 5th (romance, fun), 8th (intensity, intimacy).

Charts of the relationship itself

  • Composite chart: the midpoint of each pair of planets (your Sun and theirs, your Moon and theirs…) makes one chart for the relationship as its own living thing.
  • Davison chart: a real chart cast for the moment and place exactly halfway between the two births in time and space.

Synastry is read for attraction, emotional and physical compatibility, communication, commitment and long-term stability. As with Guna Milan, no single contact makes or breaks a relationship.

Marriage Match uses the Vedic method: Guna Milan, Manglik and dashas.
