How to Check Marriage Compatibility Beyond Porutham

In South India, the first question about any marriage proposal is usually: "How many poruthams?" The star match, with its ten poruthams, compares the two birth stars and gives a quick score. It is useful, but it is only the first step.

Two people can share seven or eight poruthams and still have horoscopes that pull in different directions. Two others with a modest score can be very well suited. This guide explains what experienced astrologers check after the porutham.

What porutham does and does not tell you

The ten poruthams (Dinam, Ganam, Mahendram, Stree Deergham, Yoni, Rasi, Rasi Adhipathi, Vasiyam, Rajju and Vedhai) all come from the birth stars and Moon signs. They describe temperament, mutual attraction and harmony.

They say nothing about:

• how strong each person's own chart is for marriage;
• the planets in the 7th house or the condition of Venus and Jupiter;
• the balance of doshas;
• the timing of each person's dasas.

That is why a star match is best treated as a screening test. You can learn about individual poruthams in our guides to Rajju porutham, Vedhai porutham and the Yoni porutham chart.

Step 1: Check each horoscope on its own

Before comparing, look at each chart separately:

1. The 7th house. Which planets sit in it and aspect it? Benefics support; a heavily afflicted 7th asks for more care.
2. The 7th lord. Where is it placed, and how strong? Our guide to the 7th lord in the 12 houses goes through every placement.
3. Venus, the natural significator of marriage in any chart.
4. Jupiter, traditionally the significator of the husband in a woman's chart and of wisdom and blessings in every chart.
5. The 2nd house (family life) and the 8th house (the continuity of married life).

A chart that is well supported for marriage on its own is the best foundation for any match.

Step 2: Look at the Navamsa

The Navamsa (D9) is traditionally called the chart of marriage. Astrologers check:

• the strength of Venus and the 7th lord in the Navamsa;
• whether the Navamsa Lagna and its 7th house are supported by benefics;
• whether the two partners' Navamsa charts relate well, for example when one person's Navamsa Lagna or Moon falls in a friendly or trinal sign from the other's.

A weak Venus in the birth chart that is strong in the Navamsa usually gives good results in married life.

Step 3: Balance the doshas (dosha samyam)

Doshas are not matched away, they are balanced. The traditional rule is that a chart with a dosha is matched with a chart carrying a similar dosha.

Dosha	Traditional basis
Chevvai (Mars) dosham	Mars in the 2nd, 4th, 7th, 8th or 12th house (many traditions add the 1st), counted from the Lagna and often also from the Moon and Venus
Rahu-Ketu (sarpa) dosham	Rahu or Ketu in the 1st, 2nd, 7th or 8th house, especially when joined with or opposed by the lords of difficult houses
Sukra (kalathra) dosham	Venus hemmed in between malefics, or afflicted in the 6th, 8th or 12th house

Most traditions also list many exceptions (for example Mars in its own or exalted sign), so a dosha found by a quick count often turns out to be cancelled. Always check the exceptions before worrying.

Step 4: Papa samyam, the malefic balance

Papa samyam compares the overall weight of malefic planets in the two charts. The malefics (Mars, Saturn, the Sun, Rahu and Ketu) are counted in the 1st, 2nd, 4th, 7th, 8th and 12th houses, reckoned from the Lagna, the Moon and Venus. Each chart gets a total.

The traditional guideline is that the two totals should be close, and that the groom's total should not be lower than the bride's. A big difference in either direction is a signal to look more carefully at the rest of both charts.

Step 5: Check the timing (dasa sandhi)

A dasa sandhi is the junction where one maha dasa ends and the next begins. These changes often bring a shift in life direction. Many astrologers prefer that:

• the partners do not both go through a maha dasa change at nearly the same time;
• neither partner starts a difficult dasa (for example of a badly placed 6th, 8th or 12th lord) soon after the wedding.

Timing does not make a match good or bad on its own, but it helps families plan the wedding date and understand the early years.

Step 6: Mental and practical compatibility

Astrology also looks at how the two minds meet:

• Moon signs. Signs in trine (1-5-9) or in the 3-11 relation from each other usually get along well. The 6-8 and 2-12 relations need more understanding.
• Lagnas. Friendly Lagna lords help day-to-day harmony.
• Mercury. Similar Mercury signs or friendly placements help communication.

And beyond astrology, values, education, family expectations and health matter just as much. A good match honours both.

Putting it together

Check	What it answers
Porutham	Are the two temperaments in harmony?
Individual charts	Is each person ready and supported for marriage?
Navamsa	How will married life feel over time?
Dosha samyam	Are the doshas balanced?
Papa samyam	Is the weight of malefics balanced?
Dasa sandhi	Is the timing comfortable for both?

Our 6-page Marriage Match report brings the ten poruthams together with the dosha checks, papa samyam and dasa sandhi, so an astrologer can review them side by side.

Summary

Porutham is the doorway, not the whole house. A careful match checks each chart's marriage houses, the Navamsa, the balance of doshas and malefics, and the timing of the dasas. Read together, these give a far more reliable and far calmer picture than a star score alone.
