Mithuna (Gemini) and Dhanu (Sagittarius) sit directly opposite each other in the zodiac. This page explains how Sinhala porondam and Tamil porutham read the pairing at the rashi level, and why the two birth stars matter more. Here, rashi means the moon sign (chandra rashi) in the sidereal zodiac used in Sri Lanka, not the sun sign printed in newspaper horoscopes.
What does the rashi count say for Mithuna and Dhanu?
Matching begins by counting from the bride's rashi to the groom's. Mithuna and Dhanu are exactly seven signs apart, so the count is 7 in both directions. The two signs face each other across the zodiac.
In the calculator, this count gives Sinhala rashi porondam: obtained and Tamil rasi porutham: obtained. That holds whether the bride is Mithuna and the groom Dhanu, or the bride is Dhanu and the groom Mithuna. It is a favourable starting point, though it is only one item among many. A full reading still has to look at the rashi lords, vashya and, above all, the two birth stars.
Are the rashi lords Mercury and Jupiter friends?
Mercury rules Mithuna and Jupiter rules Dhanu. Traditional matching asks whether these two planets are friendly towards each other. In the classical planetary relationships, the link between Mercury and Jupiter is neutral on one side and hostile on the other. They are therefore not counted as mutual friends.
For this reason the calculator shows Sinhala rashyadhipathi porondam: not obtained and Tamil rasi adhipathi porutham: not obtained. The result is the same in both directions, because the relationship between the two planets does not change when the bride and groom swap signs. This item is judged together with the others and does not settle the match on its own.
What about vashya, and does the direction change anything?
Vashya looks at a traditional sense of mutual attraction or influence between the two signs. For Mithuna and Dhanu, the calculator gives Sinhala vashya porondam: not obtained and Tamil vasya porutham: not obtained. This applies in both directions.
At the rashi level, the pairing therefore reads the same either way: rashi is obtained, while the rashi lord and vashya items are not obtained. These are only three items, though. Most of a porondam or porutham reading depends on the birth stars. As the next section shows, the direction can make a real difference once the stars are taken into account.
Why do the birth stars decide the real match?
Each rashi contains nine nakshatra quarters (padas), so this pairing allows 81 star-quarter combinations in each direction. The outcomes vary widely between them.
With a Mithuna bride and Dhanu groom, 62% of combinations pass Sinhala porondam (excluding the weekday item). None reach 8 of 10 Tamil porutham, 20% come out weak in Tamil matching, and none show a Tamil rajju clash.
With a Dhanu bride and Mithuna groom, 84% pass Sinhala porondam (again excluding the weekday item). In Tamil matching, 15% reach 8 of 10 porutham, 14% are weak, and none show a rajju clash.
Your own two stars place you in one of these combinations.
