27 Nakshatras and Marriage Compatibility — Which Nakshatras Should Not Marry Each Other

The kundali matching report is showing a low score and your nakshatra is somewhere in the middle of it. You want to understand not just that the nakshatras are incompatible — but why, and which specific pairs are the most problematic, and whether yours actually is one of them.

Here is the direct answer: four of the eight kootas in Ashtakoota matching — Nadi (8 points), Yoni (4 points), Gana (6 points), and Tara (3 points) — are determined entirely by nakshatra. Twenty-one of the thirty-six total points come from nakshatra pairs alone. This is where most compatibility scores are won or lost, and understanding each layer tells you what the number actually means.

Nadi Dosha — The Heaviest Weight in the System

Nadi Koota carries 8 points — the single highest weight in Ashtakoota. The 27 nakshatras are divided into three Nadi groups based on Ayurvedic constitution. When both partners belong to the same Nadi, the score drops to zero and Nadi Dosha is formed.

Any two nakshatras from the same row form Nadi Dosha. The most frequently encountered same-nadi pairings — because these nakshatras appear often in Indian birth charts — are Rohini with Revati or Swati (Antya–Antya), Ashwini with Hasta or Uttara Phalguni (Adi–Adi), and Pushya with Chitra or Dhanishtha (Madhya–Madhya).

One classical cancellation applies: if both partners share the same nakshatra but their Moon falls in different rashis, Nadi Dosha is generally considered cancelled per Parashari texts. The reasoning and full cancellation conditions are covered in detail in our Nadi Dosha same nakshatra different rashi post.

Yoni Koota — The Hostile Animal Pairs

Yoni Koota carries 4 points and measures intimate and temperamental compatibility. Each of the 27 nakshatras is assigned an animal symbol, and the relationship between those animals determines the score.

The enemy animal pairs — those scoring 0 in Yoni Koota — are:

Of these, Serpent–Mongoose and Cat–Rat are cited in classical texts as the most hostile Yoni combinations — not merely incompatible but actively conflicting in instinct. The others score 0 but are considered less severe.

Gana Koota — The Temperament Clash

Gana Koota carries 6 points and measures fundamental alignment of nature and outlook. The 27 nakshatras are divided into three ganas:

Scoring:

• Same gana: 6 points
• Deva + Manushya: 5 points
• Manushya + Rakshasa: 0 points in most traditions
• Deva + Rakshasa: 0 points — the most serious Gana mismatch

The Deva–Rakshasa combination attracts the most attention because the underlying temperaments are considered fundamentally opposed in their orientation toward life, relationship, and conflict. In practice, many such couples navigate this successfully — but it is a genuine signal. A Rakshasa gana person who is aware of their intensity and a Deva gana person who is not easily destabilised can build a strong marriage despite the technical mismatch.

Rajju Porutham — What South Indian Families Check First

In South Indian traditions — Tamil, Telugu, Kannada, and Malayalam communities — there is an additional nakshatra compatibility check that often carries more practical weight than all eight Ashtakoota kootas combined: Rajju Porutham.

The 27 nakshatras are grouped into five Rajjus (cords). Marriage between partners from the same Rajju is considered inauspicious — associated in classical texts with shortened lifespan of one partner. Unlike Nadi Dosha, Rajju Dosha has no widely accepted cancellation condition. Many South Indian families will not proceed with a match regardless of the guna score if Rajju Dosha is present.

The five Rajju groups, the specific nakshatra combinations involved, and which Rajju types are considered most serious are fully explained in our Rajju Porutham guide.

When Multiple Nakshatra Doshas Are Present Together

A single nakshatra dosha — Nadi alone, or Gana alone — is serious but not automatic grounds for rejection. The full picture still matters. Where Jyotishis pay closest attention is when multiple nakshatra-based doshas are present simultaneously:

Most serious combination: Nadi Dosha + hostile Yoni + Deva–Rakshasa Gana, with no cancellation conditions applying to any of them, and an overall score below 18. This pattern — losing 8 + 4 + 6 = 18 points from nakshatra factors alone before even reaching Bhakoot and Graha Maitri — is what classical texts describe as genuinely problematic.

Less concerning: Nadi Dosha with cancellation (same nakshatra, different rashi) + friendly Yoni + same Gana, with a total score above 24. The headline dosha exists, but the supporting factors are strong.
