What is Gana Dosha?
Every nakshatra belongs to one of three Ganas — Deva (divine), Manushya (human) or Rakshasa (demonic) — describing the basic temperament. Gana Dosha is mainly a marriage-matching factor (Gana Koota): a Rakshasa-gana person paired with a Deva-gana partner is the classic mismatch. In a single chart, a Rakshasa Gana simply marks a more intense, independent temperament.
