Vedic Astrology Compatibility Calculator (Nadi & Gana Koota)
This calculator helps assess a foundational aspect of marital compatibility in Vedic Astrology, focusing on two crucial Kootas (factors): Nadi and Gana. These Kootas are derived from the birth Nakshatra (lunar mansion) of each individual and provide insights into their inherent temperaments, health, and overall harmony.
Understanding Nadi Koota (8 Points)
Nadi Koota is considered the most important factor in Ashtakoota Milan, carrying 8 points. It relates to the physiological and hereditary compatibility, often linked to the three Ayurvedic doshas: Vata, Pitta, and Kapha. There are three Nadis:
- Aadi Nadi (Pitta): Represents fiery, energetic, and intellectual qualities.
- Madhya Nadi (Kapha): Represents stable, calm, and nurturing qualities.
- Antya Nadi (Vata): Represents airy, creative, and adaptable qualities.
For good compatibility, the Nadis of the prospective partners should be different. If both individuals share the same Nadi, it indicates a "Nadi Dosha" (affliction) and results in 0 points, suggesting potential health issues or lack of harmony in progeny. If the Nadis are different, 8 points are awarded.
Understanding Gana Koota (6 Points)
Gana Koota carries 6 points and indicates the inherent nature or temperament of an individual. There are three Ganas:
- Deva Gana (Divine): Represents virtuous, spiritual, and compassionate nature.
- Manushya Gana (Human): Represents balanced, practical, and worldly nature.
- Rakshasa Gana (Demonic): Represents assertive, independent, and sometimes aggressive nature.
The scoring for Gana Koota is as follows:
- Deva-Deva, Manushya-Manushya, Rakshasa-Rakshasa: 6 points (Excellent harmony)
- Deva-Manushya or Manushya-Deva: 5 points (Good harmony)
- Manushya-Rakshasa or Rakshasa-Manushya: 1 point (Average harmony, some adjustments needed)
- Deva-Rakshasa or Rakshasa-Deva: 0 points (Poor harmony, significant differences)
While this calculator focuses on Nadi and Gana, a complete compatibility analysis involves all eight Kootas (Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, Nadi) for a total of 36 points. A score of 18 or more is generally considered acceptable for marriage.
Calculate Compatibility
Examples:
Let's look at a few scenarios:
- Example 1: Boy – Ashwini (Aadi Nadi, Deva Gana), Girl – Bharani (Madhya Nadi, Manushya Gana)
- Nadi Koota: Aadi vs Madhya = 8 points (Different Nadis)
- Gana Koota: Deva vs Manushya = 5 points (Deva-Manushya)
- Total Score: 8 + 5 = 13 points
- Example 2: Boy – Ashwini (Aadi Nadi, Deva Gana), Girl – Ashwini (Aadi Nadi, Deva Gana)
- Nadi Koota: Aadi vs Aadi = 0 points (Same Nadi – Nadi Dosha)
- Gana Koota: Deva vs Deva = 6 points (Deva-Deva)
- Total Score: 0 + 6 = 6 points
- Example 3: Boy – Ashwini (Aadi Nadi, Deva Gana), Girl – Krittika (Antya Nadi, Rakshasa Gana)
- Nadi Koota: Aadi vs Antya = 8 points (Different Nadis)
- Gana Koota: Deva vs Rakshasa = 0 points (Deva-Rakshasa)
- Total Score: 8 + 0 = 8 points
