Nakshatra Porutham for Marriage — Is Star Matching Important? (English Guide)
What is Nakshatra Porutham?
Nakshatra porutham is the traditional Tamil method of checking marriage compatibility using the birth stars (nakshatras) of the bride and groom. Vedic astrology divides the zodiac into 27 nakshatras, and each person is born under one of them. The bride’s star and the groom’s star are compared across ten specific tests, together called the 10 poruthams.
The ten poruthams are: Dhina (well-being), Gana (temperament), Mahendra (progeny and prosperity), Sthree Dheerga (the bride’s long and secure married life), Yoni (intimacy), Rasi (family harmony), Rasi Athipathi (friendship between the ruling planets), Vasiya (mutual attraction), Rajju (longevity of the spouse) and Vedhai (absence of affliction between the stars).
Is Nakshatra Porutham really important?
For families that follow Tamil tradition, porutham is usually the first gate in a marriage alliance — most families expect at least 7 of the 10 poruthams to match. Astrologically, two of the ten carry the most weight: Rajju and Vedhai. Many astrologers will decline an alliance where Rajju fails even if the overall count is high, because Rajju is linked to the longevity of the marriage itself.
A practical view: porutham is a starting filter, not a final verdict. A full horoscope (jathagam) comparison — including Mangal dosha (Chevvai dosham), dasa sandhi and the seventh house — gives the complete astrological picture, and of course mutual understanding between the couple matters beyond astrology.

Frequently Asked Questions
How many poruthams should match for marriage?
Traditionally at least 7 out of 10, with Rajju and Vedhai — the two most critical poruthams — clear. A lower count with Rajju and Vedhai intact is often preferred over a higher count where Rajju fails.
What happens if Rajju porutham does not match?
Rajju failure is treated as a serious objection in Tamil tradition regardless of the total score. Families usually consult an astrologer for a full horoscope review before proceeding.
Can I check porutham with birth dates instead of stars?
Yes — our tool’s birth-date mode computes each person’s nakshatra from the date of birth and then runs all 10 porutham checks automatically, free.
