The 8 Kootas Explained: How Your Compatibility Score is Calculated

The Ashtakoot (8-Category) system is the engine of Vedic compatibility. It assigns points to 8 different aspects of life, summing up to 36. But what do these points actually measure? This guide breaks down each Koota to help you understand the specific strengths and weaknesses of your match.

1. Varna (1 Point) - Spiritual & Mental Ego

Varna classifies individuals into four categories: Brahmin (Knowledge-seekers), Kshatriya (Leaders/Protectors), Vaishya (Pragmatists/Business), and Shudra (Service-oriented).
The Logic: In ancient times, it ensured that the couple shared a similar "life mission." Scientifically, it maps to intellectual ego. If a highly intellectual person (Brahmin) marries someone who only cares about material productivity (Vaishya), their intellectual egos might clash.
Calculation: If the Groom's Varna is equal to or higher than the Bride's, it scores 1 full point. If lower, it scores 0.

2. Vashya (2 Points) - Power Dynamics

Vashya looks at "Magnetism" and "Control." It classifies the Moon signs into five categories: Chatushpad (Four-legged), Manav (Human), Jalchar (Water-dwelling), Vanachar (Wild-dwelling), and Keet (Insect).
Psychological Significance: It determines who will hold the "reins" in the house. A good score here suggests a balanced power dynamic where neither partner feels suppressed.
Example: A Lion (Vanachar) and a Human (Manav) might struggle for dominance. A Human and a Human understand each other's power.

3. Tara (3 Points) - Destiny & Long-Term Health

Tara Koot measures the health and birth destiny of the couple. It is calculated by counting from the boy's Nakshatra to the girl's and dividing by 9.
The Nine Taras: Janma, Sampat, Vipat, Kshem, Pratyari, Sadhak, Vadha, Mitra, and Ati-Mitra.
If the count lands on 3 (Vipat - Danger), 5 (Pratyari - Obstacle), or 7 (Vadha - Destruction), it scores 0. This implies that the partner brings "Bad Luck" or obstacles to your life.

4. Yoni (4 Points) - Intimacy & Sexual Nature

This is perhaps the most fascinating Koota. Every Nakshatra is assigned an animal symbol (Horse, Elephant, Sheep, Snake, Dog, etc.).
Biological Rhythm: It assesses physical attraction and chemical compatibility. Some animals are friendly (Elephant and Lion - neutral), while some are "Swabhava Shatru" (Natural Enemies), like the Snake and Mongoose.
Impact of Zero Score: If you score a zero here, it DOES NOT mean you can't have children. But it often means a lack of sexual spark. The marriage might become platonic or "brother-sister" like over time.

5. Graha Maitri (5 Points) - Mental Friendship

This measures the relationship between the ruling planets of the couple's Moon signs.
The Glue of Marriage: If Sun and Moon are friends, their personalities will "click." If Mercury and Mars are enemies, they might fight about every decision. 5/5 here is the hallmark of a relationship where you can talk all night and never get bored.
Example: Gemini (Mercury) and Virgo (Mercury) match perfectly (5/5) because they both love communication. Gemini (Mercury) and Aries (Mars) might argue (0.5/5) because Mars is aggressive and Mercury is analytical.

6. Gana (6 Points) - Temperamental Accord

Classifies souls as Deva (Divine), Manushya (Human), or Rakshasa (Intense).
The Logic: Deva souls are content; Rakshasa souls are ambitious and intense. A Deva-Deva match is super stable. A Deva-Rakshasa match is often rejected because the Deva person might feel emotionally bullied by the Rakshasa intensity.
The Cancellation: If Rashi Lords are friends (Good Graha Maitri), Gana Dosha is often ignored because the "Friendship" helps them tolerate the "Temperament difference."

7. Bhakoot (7 Points) - Emotional Stability

Bhakoot checks the distance between the two Moon signs (Rashi).
The Forbidden Distances:
- 6-8 (Shadashtak): One represents the 6th house (enemies) to the other, and the other represents the 8th house (death/transformation). This brings intense conflict.
- 2-12 (Dwadasha): One represents loss (12th) to the other's wealth (2nd). This brings financial stress.
- 5-9: Usually good, but sometimes indicates ego clashes regarding children.

8. Nadi (8 Points) - Physiological Constitution

The final and most important check. It classifies people into Adi (Vata), Madhya (Pitta), and Antya (Kapha) Nadis.
The Rule: Two people of the same Nadi MUST NOT marry (Nadi Dosha), as it implies they are "too similar" at a biological/genetic level, potentially leading to weakened immune systems in progeny.
Exceptions: If the Groom and Bride belong to the same Moon sign but different quarters of the Nakshatra, the Dosha is cancelled.

Koota Max Points Effect on Score Zero
Graha Maitri 5 Constant misunderstanding; unable to communicate simple feelings.
Gana 6 Frequent behavioral friction; clashing reactions to stress.
Bhakoot 7 Financial struggle or severe emotional gap (Bhakoot Dosha).
Nadi 8 Genetic incompatibility; risks to health of couple/children.

Detailed FAQ on Ashtakoot

Q1: Which Koota is the most dangerous to fail?
Nadi (8 points). It hits the health/genetic pillar. Bhakoot (7 points) is second.

Q2: My Nadi is 0 but Gunas are 24. Should I worry?
Yes. A score of 24 with 0 Nadi is a "Deceptive Score." Check for Nadi cancellations (same Rashi lord, different Padas) immediately.

Q3: Is Yoni Koot only about sex?
Primarily, yes. But it also reflects "Animal Instincts"—how you sleep, eat, and relax. If Yoni matches, you feel physically comfortable in each other's silence.

Q4: Why does Varna only have 1 point?
Because in the modern world, work/caste roles are fluid. A Brahmin can do business, a Vaishya can teach. Spiritual ego is less critical for survival than Health (Nadi).

Conclusion
