Every nakshatra falls into one of three temperament groups — Deva, Manushya, or Rakshasa — and this factor lines up the bride's group against the groom's. Same-group or Deva-Manushya pairings read as an easy personality fit. A Deva paired against Rakshasa is the combination astrologers flag as needing more attention, since the two temperaments are seen as pulling toward opposite instincts.

Mahendra is specifically about children — whether the star positions of both partners point toward a family line that continues comfortably. Couples who weight family planning heavily in their decision tend to pay closer attention to this particular koota than most.

Unlike most kootas, this one centers specifically on the bride — her health and longevity within the marriage, worked out from the star-distance between the two nakshatras. A strong result here is often read by the bride's family as a sign the match won't come at the cost of her own long-term wellbeing.

Each nakshatra carries an animal symbol standing in for its underlying instinctive nature, and Yoni compares the bride's symbol against the groom's. Matching or friendly-animal pairs suggest natural physical and emotional ease; opposed pairs — the classic example being cat and rat — signal friction that a couple may need to actively work through.

This factor sets the two moon signs, or Rasis, side by side. Since the moon rules the mind in Vedic astrology, the Rasi pairing is taken as a read on emotional depth and how naturally the couple will understand each other day to day. Some Rasi pairs line up smoothly; others suggest the couple will need to put in more deliberate effort to stay emotionally aligned.

Where Rasi Porutham stops at the moon signs themselves, this one goes a layer deeper — comparing the planetary rulers (Adhipatis) of each Rasi. Those two ruling planets can be natural friends, neutral toward each other, or outright enemies in classical planetary relationships. Friendly or neutral rulers support cooperation; enemy rulers are read as a quieter, underlying source of tension.

Vasya is about influence — which partner's moon sign naturally holds more sway over the other, and whether that balance of influence sits evenly or tips heavily one way. A well-matched Vasya reading is associated with a relationship where neither partner ends up dominating the household by default.

Of all ten factors, this is the one Kerala astrology treats as non-negotiable. Nakshatras sort into five Rajju groups, each tied symbolically to a part of the body, and the check is simply whether bride and groom land in the same group. A Rajju dosha here is rarely waived, even when the rest of the report reads well — it's considered directly tied to the couple's physical safety and longevity.

This is a final obstruction check — certain specific nakshatra pairs are classically flagged as working against each other regardless of how the other nine factors turn out. Astrologers typically hold this one back as a last review, since a Vedha flag can quietly undercut an otherwise strong-looking match.
