Avakahada Chakra (Varna, Vashya, Yoni, Gana, Nadi)अवकहड़ा चक्र
A set of five classical classification tags — Varna, Vashya, Yoni, Gana, and Nadi — derived purely from your birth Nakshatra and Rashi, all shown together in the Birth Summary card. These same five categories are exactly what the Ashtakoot Guna Milan compatibility system compares between two people (see the Matching glossary for full detail on each).
On the Kundli page these five tags are shown mainly as descriptive facts about your own chart; their real practical use comes into play on the Matching page, where they're compared point-by-point against a prospective partner's chart.
All five are looked up from fixed classical tables keyed to your birth Nakshatra (and, for Vashya, your Rashi) — no separate calculation beyond determining those two values first.
