Mrityu Shadastak and Preeti Shadastak signs.
In Preeti Shadastak both zodiac signs are either ruled by same planets or rashi lords are friendly planets. This promotes harmony in their relationship inspite of having many differences. They still get attracted to each other in the long run.
Zodiac Signs that make Preeti Shadastak yoga are as follows :-
- Aries-Scorpio —> Both are ruled by planet Mars.
- Tauras- Libra —> Both are ruled by planet Venus.
- Gemini – Capricorn —> Rashi lords Mercury and Saturn are friends of each other.
- Cancer – Sagittarius —> Rashi lords Moon and Jupiter are friendly towards each other.
- Leo – Pieces —-> Rashi lords Sun and Jupiter are friendly towards each other.
- Virgo – Aquarius —> Rashi lords Mercury and Saturn are friends.
Zodiac Signs that make Mrityu shadastak yoga are as follows :-
- Aries – Virgo —-> Mars and Mercury are worse enemies.
- Tauras – Sagittarius —-> Venus and Jupiter are enemies.
- Gemini – Scorpio —–> Mercury and Mars again.
- Cancer – Aquarius —–> Moon and Saturn are enemies.
- Leo – Capricorn ——> Sun and Saturn are enemies.
- Libra – Pieces —–> Jupiter and Venus are enemies.
From the above table it is clear that :-
- Preeti shadastaka happens between rashi/zodiac signs owned by same planet or friendly planets.
- Grah maitri koota gets full points in gun-milan for Preeti Shadastaka.
- Mrityu shadastaka happens between the rashi/zodiac signs inimical towards each other. The lords of these signs are strong enemies.
What is the difference between Preeti Shadastak and Mrityu shadastak?
Preeti shadastak is shadastaka of signs whose lords are friendly to each other or both signs are owned by same planet. It promotes love and well being inspite of having many differences with each other. These people can be friends as there fights and differences mellow down due to their attraction for each other.
Mrityu Shadastak is shadastaka of signs whose lords are worse enemies of each other. These people will feel strained and suffocated in a relationship in the long run. The initial attraction and love fades away with time bringing a lot of stress in relationships. It kills the relationship between two people in the long run.
Does Mrityu shadastak cause death? Is it death shadastak?
Absolutely not, the word Mrityu indicates death of the relationship due to stress, fights and lots of differences in the long run. They began to despise each other and develop hatred at some point if there are other extreme combinations in the horoscope. Their relationships turn sour due to incompatibility between them which kills it.
Even in general relationships you will realize that you do not get along with certain people inspite of trying very hard for it. There are a lot of differences between the two people which does not let them have a harmonious relationship, they might began as best friends but end as worse enemies of each other. This happens in mrityushadastaka.
Loose interpretation of astrological sutras leads to spreading such fears and rumors in the society. Mrityushadastaka does not kill anyone but spoils the relationship resulting in death of the relationship between two people as things reach beyond tolerable levels for both at some point.
Remedies for shadastak dosha
Rashi shadastak is not a dosha. There are no remedies for Rashi shadastak, it is just that the mental make up of two people is not compatible for each other. If the promise of marriage and married life is good in the horoscope there won’t be severe issues in the relationships.
There will be friction and stress in relationships leading to no attraction and love between the two people if bad planetary combinations are there in the horoscope. Some people just live with each other for entire life inspite of having no compatibility, no respect, no attraction for each other, they can be an example of mrityu shadastak.
Conclusion:- Rashi shadastak does not cause death.
- Signs having Preeti Shadastaka can marry each other.
- Signs having Mrityu shadastaka should possibly avoid tying the wedding knot.
Note: Complete horoscope analysis should be done before reaching any conclusion. Just having a rashi shadastak yog does not ensure bad married life or a bad horoscope compatibility. Other supportive planetary position do modify the outcome and some rashi shadastak people can share good relationships.

Frequently Asked Questions — Rashi Shadastak
Is Mrityu Shadastak a reason to reject a marriage proposal?
Not necessarily. Mrityu Shadastak means the temperaments of two people are fundamentally conflicting — their natures do not sync. A person’s core temperament rarely changes, which is why Moon Shadastak carries real weight. In cases where the 7th house, 7th lord and promise of married life are weak in the individual charts, Mrityu Shadastak can lead to mental frustration, constant friction and eventual death of the married life — not death of the partner. However where the 7th house is strong and the promise of marriage is good, many couples with Mrityu Shadastak adjust and compromise and build a workable married life. Complete horoscope analysis is essential before any decision.
What is the difference between Moon Shadastak and Lagna Shadastak?
Moon Shadastak checks the 6/8 relationship between both partners’ Moon signs. The Moon represents temperament and swabhav — and since a person’s core nature rarely changes, Moon Shadastak indicates deeply different natures that create friction in day to day married life.
Lagna Shadastak checks the 6/8 relationship between both Ascendant signs. The Lagna represents the physical body, personality and the entire framework of life. When two Lagnas are in Shadastak, the sync across all 12 houses gets disturbed — not just emotionally but physically and constitutionally. Such couples are often visibly mismatched — different body types, different physical constitutions.
More significantly, the 5th house governs progeny. When Lagna Shadastak disturbs this sync, it can manifest in children born with health concerns or constitutional imbalances — the genetic and constitutional incompatibility of the parents expressing itself in the next generation. This is also why Nadi Dosha and Shadastak are studied together in classical Jyotish — both point to deeper constitutional mismatches beyond mere temperament.
The more Shadastak combinations present between the planetary positions of both horoscopes beyond just Moon and Lagna, the deeper and more pervasive the differences in the relationship become.
Can Shadastak dosha be cancelled or reduced?
Shadastak is not a dosha with classical cancellation rules like Nadi Dosha or Mangal Dosha. Its impact depends entirely on the strength of the 7th house and 7th lord in both charts and the overall promise of married life in each individual horoscope. A strong 7th house and good marriage promise can allow a couple to adjust to each other’s different natures despite Mrityu Shadastak. Preeti Shadastak is far less harmful because the rashi lords are friendly — the differences exist but there is an underlying harmony that holds the relationship together. Where Graha Maitri score in Gun Milan is high, the negative impact of Shadastak is also moderated.

My rashi lord is venus and my grooms rashi lord is mercury. Can the shadashtak be cancelled in this case. Please advice
Namaste Anisha,
Mercury and Venus Rashi do not make Shadastaka. They are either 2/12 Dwidwadash (vrishabh/Mithun or Kanya/Tula) from each other or in 5/9 trine (Mithun/Tula or Vrishabh/Kanya) from each other.
Rashi lords are friendly hence the dwidwadash can be ignored. But having said that, horoscope compatibility is a very detailed process than just checking gun-milan.

Namaste Chinmaya,
Please opt for paid consultation for horoscope compatibility. It is not just about checking gun-milan or shadastaka dosha in both horoscope but goes much in detail beyond that. Both individual horoscopes have to be checked for promise of marriage/married life, progeny, longevity etc after which compatibility between planetary positions is checked followed by checking dosha samya, gun-milan etc before giving conclusion.
Thanks and regards,
Ashish Desai.
