Most of the Indians do arranged marriage. One part of the process is the horoscope matching. The horoscope matching process itself varies based on language, religion, caste, location etc. I am going to dissect one such process which is mainly followed by people in south India. I don’t have much knowledge about horoscope or anything related to astrology, neither do I believe in it. So it is possible that I might have misunderstood some aspects of the process. So take anything I say with a grain of salt. I am using tamilhoroscope.in as the main source for the rules.

Porutham is a sub part of the matching process. Each individual porutham projects a specific aspect of a marriage life. For example Dhinam porutham projects the opinion and understanding between the couples in everyday life. There are 8 main poruthams namely Dhinam, Ganam, Mahendra, Rasi, Nadi, Yoni, Rajji and Vedhai. Every porutham need not match to be considered a successful match. A successful match can be succinctly described using boolean operators as

(Dhinam || Ganam) && (Mahendra || Rasi || Nadi) && Yoni && Rajji && Vedhai

There are 27 nakshatras and 12 rasis. A person’s rasi and nakshatra are calculated using their birth date and time. Each porutham can be described as a set of rules.

Dhinam

For each and every day to be a very special day for the couples they must have their match of Dhina porutham. Only this match will eliminate the difference of opinion and misunderstanding between the couples. This match is made as follows:

  1. If a remainder of 2, 4, 6, 8, 9 is obtained when you divide the counting of stars from female’s star to male’s star by 9 then this match is fulfilled.

  2. If the counting from female’s star to male’s star is 2, 4, 6, 8, 9, 11, 13, 15, 17, 18, 20, 22, 26, 27 then this match is fulfilled.

  3. If both male and female are of the same rasi or belong to different Phase of the same star then this match is fulfilled.

  4. If both male and female are of Bharani, Avittam, Sadhayam or Poorattathi stars then this match is not fulfilled. Both having any of the above stars for them should in fact avoid getting married.

Ganam

There are 3 Ganams as per astrology. They are Deiva Ganam, Manitha Ganam, Ratchasa Ganam. All the stars would definitely fall in any one of the above ganams. This match is viewed especially to arrive at the tolerance level between the couples. If the couples have this match in their horoscope then they will tolerate each other and avoid misunderstandings.

  1. Ashwini, Murugashreedam, Punarpoosam, Poosam, Hastham, Swathi, Anusham, Thiruvonam and Revathi are the stars belonging to Deiva ganam.

  2. Bharani, Rohini, Thiruvadirai, Pooram, Uthiram, Pooradam, Uthiradam, Poorattathi and Uthirattathi are the stars belonging to Manitha ganam.

  3. Karthigai, Aayilyam, Magam, Chittirai, Visakam, Kettai, Moolam, Avittam and Sathayam are the starts belongings to Ratchasa ganam.

A male and a female belonging to the same ganam or even if either belong to deiva ganam and other belong to manitha ganam they can get married.

If the male belong to deiva ganam and the female belong to ratchasa ganam then they do not have gana porutham on the contrary if the female belong to deiva ganam and the male belong to ratchasa ganam then this match is fulfilled.

Mahendra

Mahendra porutham is matched for puthira bakkiyam(blessed with a child). This match will hint the flow of the generations of that particular family.

If the counting from the female star to the male star is 4, 7, 10, 13, 16, 19, 22, 25 then this match is fulfilled.

Rasi

Rasi porutham is one of the many matches looked for vamsa viruthi and as per few sasthras this match will give all the happiness and the blessings to have a male child for the couples getting married.

If the counting from the female star to the male star

Is above 6 then matching is fulfilled

Is 8 then there is no match

Is 7 then the matching is excellent

Is 2, 6, 8, 12 then there is no match

Is 1, 3, 5, 9, 10, 11 then the matching is ok

Also Kumbam and Simam, Magaram and Kadagam are the rasis that do not match with each other.

Nadi

This match is being looked for to denote the matching between the blood groups of the male and female. Budhira Bakkiyam for the couples having this match is confirmed.

In general Nadi is divided into three divisions. If both male and female belong to the same Nadi then this match is not full filled. And if both Male and female are of different Nadi then this match is fullfilled.

Paarsuva Nadi - Ashwini, Thiruvathirai, Punarpoosam, Uthiram, Astham, Kettai, Moolam, Sathayam, Puratahi

Yoni

As per this match each and every star is identified as an animal. This match is not fulfilled if there is a enemity between the yoni(animals). And for fulfillment of this match there should not be enemity between the animals(yoni) matched.

Rajii

This is the most important match that is looked for while matching the horoscopes. For the persons getting married, even if nine out of ten matches are full filled and if this Rajji porutham is not fulfilled then it is not recommended for them to get married. Our ancestors have given such an importance for this match. Rajju is being divided into five parts.

Siro Rajii - Mirugasrisham, Sitthirai, Avittam

Kanda Rajii
Arohanam - Rohini, Astham, Thiruvonam
Avaraohanam - Thiruvathirai, Swathi, Sathayam

Uthara Rajii
Arohanam - Karthigai, Utharam, Uthradasm
Avaraohanam - Punarpoosam, Visaham, Purattathi

Uuru Rajii
Arohanam - Barani, Pooram, Pooradam
Avaraohanam - Poosam, Anusham, Utthiratathi

Paadha Rajii
Arohanam - Aswini, Magam, Mulam
Avaraohanam - Ayilam, Kettai, Revathi

Matches are looked for in such a way that if the stars of both male and female are not of the same Rajji then the female will lead the life as Dhirka Sumangali.

There are two divisions in the same Rajju like Arohanam and Avaraohanam. There is an opinion that even If the stars of the male and the female are of the same Rajju but belong to Arohanam and Avarohanam then the horoscopes are matched and proceeded for marriage.

Vethai

This Vethai Porutham denotes the power of Mangalya Kayiru and is one of the basic match that is being looked for. If both male and the female stars are Vethai then this match is not fullfilled and the others have Vethai match.

Ashwini - Kettai
Bharani - Anusham
Karthikai - Visakam
Rohini - Swathi
Thiruvathirai - Thiruvonam
Punarpoosam - Uthiradam
Poosam - Puradam
Ayilam - Moolam
Magam - Revathi
Puram - Uthiratathi
Uthiram - Uthiratathi
Hastham - Sathayam

Above are the stars that do not match with each other. And matching the above stars is not a good match.

Dhinam || Ganam

Mahendra || Rasi || Nadi

(Dhinam || Ganam) && (Mahendra || Rasi || Nadi) && Yoni && Rajii && Vethai
