At first he got the Chief Minister’s chair by default on Annadurai's death.
He became CM on 10-02 1969.
The period was Saturn dasa- Mercury bhukthi.
Here Sasa yoga did not work. Vipareeta Raja yoga worked as he got the post by default. . 8th lord Saturn and 12th lord mercury aspecting each other from kendras (4th and 10th) made this happen.
However he lost in Saturn – Moon in 1976.
Once the moon antardasa started, he started getting worries due to MGR.
For the behavior of dasa- antardasa lords, we have to first see the angle between the lords. It must be favorable. Saturn and Mercury are in mutual aspect.
In contrast Saturn- Moon they are in 8-6 axis. Such an axis strains the relationship between the planets in their periods.
Moreover, though Moon is the lagna lord, it is weak in shad bala strength. One of the important determinants for a person to rise to power is to have three or four planets in dig bala (‘300 important Combinations’– 247th yoga). Shadbala strength can not be ignored in assessing how much a planet can do. Moon is the weakest in Dig bala and very less in sthana bala and kala bala.
The weak kaala bala and sthana bala of moon will work adversely in adverse dasa lords. He lost to MGR in Saturn dasa and Moon antardasa. Saturn is 8th lord from Cancer and is in 6th from moon.
The lesson is that whatever be the planet that causes Raja yoga, if the antardasa lord is adverse to it and is weak on its own, there will be a dent in the Raja yoga.
Karunanidhi got back to power in 27-01- 1989 after 14 years, when Mercury - Venus was set in. These 2 planets are on both sides of Sun and moon thereby causing Ubhaya chara and Duradhara yogas.
He lost in
His next rise was in
Though the angle between Mercury and Jupiter is not good, the asterisms in which they are placed are Venus and Mercury - a repeat of the best of solar and lunar yogas as mentioned above. (Duradhara and Ubhaya chara)
He lost in
The period was Ketu- Venus. This was the time most astrologers thought that he would take political sanyas. The strong reason is that Ketu, Venus and Saturn share the Tapaswi yoga in his horoscope.
Though Ketu and Venus as dasa and antardasa lords shared a good angle in rasi, they are in 6-8 angle in bhava. Ketu is in the asterism of Mars and Venus is in Jovian asterism.. Jupiter as 6th lord has 1 bindu in martian ashtaka varga. The fall was inevitable. If we see the previous periods he had been to the jail for most times in Jupiter maha dasa. This combination almost seemed to seal his return to power.
But that was not to be so because the exalted planets also must give their contribution. He came back to power in Ketu - Saturn on 13-05- 2006 . Both these planets are in the star of Mars, the yogakaraka and the 10th lord who enjoys Ruchak yoga.
His entire family grew in wealth more than ever before during this period. His courage found no bounds as he even questioned who Lord Rama was. Without any inhibition he went about his ways only during this tenure.
The current trend.
This can be arrested only when moon sets in.
The antardasa of moon in the current Venus mahadasa begins on April 7th this year and will last until
Venus – moon angle is such that moon is 2nd lord in the 12th to Venus.
The weak dig bala of Moon has caused him to lose support from the North. Though he has firmed up an electoral deal with his Northern partner, he is still in fear of indictment from the Supreme Court on the Spectrum scam.
Updated on 13-04-2016:-
Since 2007, Karunanidhi has been running Venus Maha dasa which will last for 20 years. Venus being a Baadhaka for his horoscope, this dasa will not be a fortunate one.
That the horoscope produced in the above article is an authentic one can be proved from the fact that Karnanishi has a trouble in his left eye for more than 60 years. Venus in the 12th house signifies trouble to the left eye.
Recently he wrote in a letter that his trouble with his left eye started in the year 1953 due to an accident. At that time transit Saturn was in retrogression in Virgo and Venus in retrogression in Pisces. Saturn, the 8th lord on his natal chart was aspecting Venus in transit in the Pisces and the 12th house (Gemini) which signifies left eye. The period was Jupiter dasa - Mercury Bhukthi. Jupiter is the 6th lord and Mercury, the 12th lord. Thus this left eye problem is a confirmation of this birth chart and the events that had happened.
Now he is running the dasa of Venus which is a Baadhaka and also an occupant of the 12th house.
So it is not possible to expect positive results in this dasa. This was earlier confirmed in the loss in 2011 assembly elections and 2014 Lok sabha elections. The same will be repeated in May 2016 elections too.
Presently (at the time of elections in May 2016) he is running Venus Maha dasa - Rahu Bhukthi. Venus is a Baadhaka and is in the star of 6th lord Jupiter. So its malevolence with reference to loss of health & money and gain of enemies besides misfortunes is a forgone conclusion.
The Bhukthi lord Rahu is in the 2nd house which is a Maraka (marana) sthana. It is in the star of Ketu which occupies the 8th house. Both signify attrition and maraka like happenings. At present, transit Saturn is in Scorpio joined with Mars which is a malefic combination. At the time of writing this, Saturn is regressing in the natal degree of Jupiter, the 6th lord in his natal horoscope. At this time his candidature has been announced. From Scorpio Saturn is aspecting transit Rahu by 10th aspect and Moon, the lagna lord and Sun, the sign dispositor of Rahu by 7th aspect.
This greatly affects his success and also increases attrition in health. At the time of elections he will be running Venus dasa - Rahu Bhukthi and Venus Antharam. This is a baadhaka combination.
From November 1st 2016 to January 19th 2017 Mars and Saturn are going to aspect Rahu and his 2nd house. That would be a very bad time for him. More misfortunes await him in the 2nd half of this year.
