Marriage is not just a union of two bodies but a meeting of two souls. In Vedic Astrology, the compatibility between two people is determined by analyzing their birth stars (Nakshatras) against 12 specific criteria known as Kutas.

Most online calculators only check 8 factors (Ashtakoota), but the legendary astrologer Dr. B.V. Raman, in his classic book Muhurtha, emphasized a more comprehensive 12-factor system. This system dives deeper into psychological, spiritual, and biological compatibility.

Our Match Checker tool is built entirely on these rigorous principles set forth by B.V. Raman.

The Scientific Basis

According to B.V. Raman, "The Kutas typically refer to the agreement of the mind, the agreement of the body and the agreement of the soul."

While modern dating often focuses on shared hobbies or physical attraction, the Vedic system looks at:

  • Mental Wavelength: Can you communicate without friction?
  • Biological Health: Is there genetic compatibility for healthy children?
  • Longevity: Will the union support a long life for both partners?

The 12 Kutas Explained

Here are the 12 factors checked in a complete Vedic horoscope match:

Indicates luck and daily living compatibility. A bad Dina Kuta can lead to minor health issues and daily friction.

Classifies people into Divine (Deva), Human (Manushya), and Demon (Rakshasa) temperaments. A Deva marrying a Rakshasa usually leads to conflict unless other factors neutralize it.

Ensures longevity of the bond and well-being of children. This is a critical factor for family growth.

Represents the woman's well-being and longevity. It ensures the husband's star is "far enough" from the wife's to allow her space and respect.

Analyzes sexual urge and compatibility through animal symbolism (e.g., Horse vs. Deer). Hostile animals indicate dissatisfaction.

Checks the position of the Moon signs relative to each other. Avoiding the "6/8" (Shadashtaka) relationship is crucial to prevent constant quarreling.

  • Graha Maitri: Friendship between the planetary lords of the Moon signs (Mental harmony).
  • Vasya: Magnetic attraction and amenability.
  • Rajju: Duration of married life (Felicity). A very serious factor; mismatch here is dangerous.
  • Vedha: Affliction or repulsion. Certain stars mutually repel each other.
  • Varna: Spiritual development and capacity.
  • Nadi: Nervous/genetic energy. The most important factor (8 points). Mismatch (Nadi Dosha) warns against marriage.

Doshas and Exceptions

B.V. Raman notes that "One should not be carried away by the mere number of points." Even if the score is high (e.g., 25/36), a single "Dosha" (flaw) like Rajju or Nadi can break the marriage.

Conversely, a lower score might be acceptable if certain exceptions (cancellations) are present. For example, a bad Rasi Kuta is neutralized if the lords of the signs are friends (Graha Maitri).

Our Match Checker takes all these subtle cancellations into account, unlike simple point calculators.
