What is Graha Maitri?
Graha Maitri (also spelled Graha Mytri) tests the compatibility of the ruling planets of both partners' Moon signs. First, the lord of each partner's Moon sign is identified. Then the natural friendship or enmity between those two ruling planets determines the score. This kuta reflects mental and intellectual compatibility — how well partners think alike and understand each other's minds.

Significance
Graha Maitri reflects how compatible the couple's thought processes, beliefs, and mental outlooks are. Friendly planetary lords indicate that partners will naturally understand each other, share similar values, and support each other's goals. Enemy lords suggest chronic mental friction — each partner may feel fundamentally misunderstood by the other, even if they are physically and emotionally attracted.
