It is widely believed that the placement of the 7th lord in the dual signs is an indication for a second marriage. But that is not true. Actually, the placement of the 7th lord in the cardinal signs strongly signifies the possibility of a second marriage, even though it is not the only factor deciding it. This has been unequivocally spelt out by the saptarishis (seven sages) in Saptarishi Nadi.
Saptarishi Nadi is a collection of books containing discussions of horoscopes by the seven sages (saptarishis) and the consort of Lord Siva, Devi Parvati, herself. It is written in poetic form in the Tamil language. These books were compiled from palm manuscripts found in various parts of Tamilnadu, India, and published by the Government Oriental Manuscripts Library, Madras. Most importantly, they are a treasure house for those who want to analyze the predictions of the horoscopes by the ancient sages. I have discussed at length about this collection in the Saptarishi Nadi section. I have compiled the portions where the saptarishis put forth their arguments in favor of/against some of their predictions in the form of an eBook titled, “Elucidation of astrological predictions by saptarishis: Saptarishi Nadi, Aries ascendant collection.”
Indications for/against second marriage
Let’s take a look at horoscope 52 of the eBook, which illustrates this concept clearly.
The 7th lord, Venus, is placed in Cancer, which is a cardinal sign. This happens to be the 4th house and also one of the kendras. Mars — the lagna lord and the 8th lord — aspects the 7th house (Libra); no other planet aspects the kalathra sthanam.
The following is the discussion among the seven sages and Parvati devi on the possibilities for a second marriage. Color codes: pink for Parvati Devi and other colors for each of the saptarishis.
Possibilities for a second marriage
பாலிகை வயதுதீர்க்கம் பிருகுமே மறித்துச்சொல்வார்
வேல்வழி இரண்டுஎன்று விளம்புவோம் பாலனுக்கு
சாலவே விபரம்சொல்வாய் சத்தமத்தோன் சரத்தில்
இருப்பதால் தாரம்ரெண்டு இயம்புவோம் முனியேயானும்
குறுமுனி புகலுகின்றார் கூறொணா தாரம்ரெண்டு
வருமாறு சொல்லுமென்ன மதிக்கேழில் குருவும்தங்க
குருதியன் ஏழைப்பார்க்க கூறொணா தாரம்ரெண்டு
இதற்கு நேரிடையாகச் சாதகசுருதி இதிலேழாம் பாவத்தில்பாரு
அதில்சொல்லும் விபரம் ரெண்டேழோன் கேந்திர மாகிலும்கோ ணத்திலிருக்க
வதிபதி ஒன்றேவரைந்தனம் தாயே மன்னு வர்க்கினில் பரல்ஒன்று
சதியிலா திருக்கதாரம் ஒன்றே சாத்திய பலன்களைக் கேளாய்
His wife will live long.
Sage Bhrigu interjects that the jataka will have two wives.
Explain why you said so.
As the 7th lord is in a cardinal sign, he will have two wives.
Sage Agasthiya disagrees and says that the jataka will not have two wives.
Why did you say so?
Jupiter is placed in the 7th house from the Moon, and Mars aspects the 7th house. Therefore, he will not have two wives. Kindly refer to the 7th chapter in Jataka suruthi which clearly says that if the 2nd/7th lords are placed in a kendra or kona, a jataka will have only one wife. Also, as only one paral (point) is seen in the varka chart, he will have only one wife.
As you can see, the only blemish sage Bhrigu mentions is the placement of the 7th lord (Venus) in a cardinal sign (here, Cancer). Luckily for our jataka, other favorable factors mitigate this deleterious effect:
- Venus happens to be in a kendra, and therefore the jataka will have only one wife.
- Mars aspecting the 7th house turns out to be beneficial, may be because he is the lagna lord.
- In addition, the sages say that Jupiter in the 7th house is favorable (here, counted from the Moon) which tilts the balance towards a single wife.
This is not a one-off mention in the Saptarishi Nadi series; this concept is encountered in many of the horoscopes discussed. I’m not sure if any of the sanskrit classics explains this concept, but I can quote two of the verses from Jataka alankaram, a Tamil astrology classic penned by Keeranur Natarajan in the 18th century.
Reference from a Tamil classic
Jataka alangaram mentions this rule in verse 649:
ஏழ்வீட்டி னிற்கதிபன் சரத்தினிற்கில் இருமனைவி திரமதனி லிருக்கநன்றே
தாழ்விலா உபயத்தி லிருக்கின்மாதர் சாவின்றிப் பலருளராம் .....
If the 7th lord is placed in a cardinal sign, he will have two wives. If placed in a fixed sign, all is well. If placed in a mutable/dual sign, his wife will not die (he will have only one wife), but he will have many extramarital affairs.
In verse 658, the author also says,
If the 2nd/7th lords are placed in a kendra or trikona, he will be affectionate and stay loyal to his wife and wants no other.
Not convincing enough?
In case I was not persuasive enough, let us take a look at one more horoscope that exhibits this concept. Horoscope 32 of the eBook makes this point exceedingly clear once again.
In this horoscope, the 7th lord, Venus, is placed in the 4th house (Cancer) along with the Moon. Neither Saturn nor Mars aspects Venus, but Saturn does aspect the 7th house. Certainly, Cancer is a cardinal sign, and it is a strong indication for a second marriage, per Parvati Devi herself!
When the sages predict that the jataka’s wife will live a long life, She rightfully questions the rationale behind it.
Cardinal sign indicates second marriage
எப்படி வயதுதீர்க்கம் ஏழினுக் குடையோன்தானும்
தப்பாத சரத்திலேறச் சாற்றினீர் தீர்க்கமெவ்வார்
அப்படி சொல்லொணாது அந்தணர் குடும்பம்நிற்க
மைப்படி மாதுஒன்று மருவாது வேறுதாரம்
Parvati Devi asks, “How did you say that his wife will live long? As the 7th lord is placed in a cardinal sign, how can you say so?”
“As Jupiter is in the 2nd house of family, he will have only one wife. A second wife is not a possibility.”
Here we have it once again! The 7th lord being placed in a cardinal sign is detrimental for the longevity of the first wife. Thankfully, Jupiter in the 2nd house is beneficial enough to thwart such a possibility.
Summing it up
It is exceedingly clear from the above discussion that the 7th lord, if placed in a cardinal sign, indicates a strong possibility of a second marriage, as expounded by the Saptarishis. On the contrary, the 7th lord being placed in a kendra or trikona is beneficial for a stable and prosperous marriage. Obviously, other factors do weigh in, as seen in this horoscope, in deciding the success and stability of marital life.

Please note that the saptarishis used a tropical zodiac with sidereal nakshatras — which I have established conclusively in another article — and the rules discussed in Saptarishi Nadi were intended for interpretation of a chart computed with tropical zodiac, as opposed to sidereal zodiac.
