There
are many "Dosha" or Dosham (errors, short coming or harsh planetary
combinations) explained in Jyotish - Vedic Astrology.
The
most popular one is Mangal Dosha/Dosham (as known in North India) and Kuja
Dosha/Dosham in South India. Mangal Dosha/Dosham is also known as - Mangli,
Manglick.
What
is Mangal Dosha? By the best astrologer in Delhi.
Now
coming backs to Rahu Dosha/Dosham. Rahu is one of the 9 planets in Jyotish - Vedic Astrology. Rahu in Western
Astrology is known as "North or Ascending Node". You may learn more
on Rahu and Lunar Node. The other or opposite of Rahu is Ketu, aka "South
or Descending Node".
The
actual word(s) "Rahudosha or Rahu Dosha" does not exist in Jyotish -
Vedic Astrology.
Rahu Dosha is an author's privilege word or phrase. I
will use it in my analysis, interpretation, and writing.
Let me show you some example of Rahu
Dosha -
- Rahu, Lagna and Moon are conjoined.
- Rahu in the 1st house, 2nd, 5th, 7th, 8th, 9th and 12th house of Rasi or Chandra Lagna.
- Rahu aspect Moon or Lagna 5, 7 and 9 houses.
- Under the aspect of Rahu, Moon does not receive any aspect from Jupiter.
- Rahu does not receive aspect from Jupiter.
How long would it impact a person?
How long is an impact of Rahu - If you cannot change the date, time and
city of birth of the native/seeker? Similarly, Rahu dosha cannot be altered or
changed. It's due to happen and will take place, especially during Rahu Dasha,
antardasha etc. this is a lifetime issue. Rahu Dosham impact may last from 10
months 24 days to 18 years long, however, it also depends if the next dasha is
somehow linked with Rahu or not. If the next dasha lord is linked with Rahu,
then the next dasha - from 6 years to 20 years long will have the impact of
Rahu dasha, this cycle can continue further if Rahu is still connected to the
next and the next dasha lord. All the dashas need to be analyzed and
interpreted.
Impact or results of Rahu Dosha - Whenever, Rahu, Moon and Lagna are
conjoined (or are in the situation described above), joining or separating to
neighboring house/zodiac sign, aspect each other and there is no benefic aspect
or influence from Jupiter to such a Moon. This is called Rahu dosha. Its impact
is on native's marriage. In such a case, marriage is delay, denied, multiple
marriages are indicated (in one case I saw one of my male clients got married
16 times and a female client seven times - both cases all spouses were
foreigners), marriage is a foreigner - whose not born on the city, state or
country of the native. The language, culture, religion and way of life etc are
in contrast with the native. Should marriage takes place with a spouse born in
the same city, state or country, the marriage does not last. Marriage is a
foreigner, multiple marriages are indicated. In Rahu Dosham, I have noted or observed
that at the end of life, the native is without a married partner, living a
lonely existence. In Rahu Dosham the native is deserted by his spouse,
children, relatives, business associates and more.
How long would it yield negative
results to a person?
It
is possible you may not like my interpretation above. It's okay, I understand,
it's not to your liking or it's too negative, I have heard these words many
times before, but this what your birth chart shows and I interpreted it
"as is" without any "sugarcoated" words. You wish it was
different. You know something, you can change it, and you can change all that I
wrote if you want to. How? Just use your "creative intelligence" and
change it. Yes, anyone can change their destiny, alter karma and rewrite their
fate (well only if they had known about it and now you know about it, well you
don't have accepted it or believe it) it all can. It's No interpretation or
prediction is "writing on the rock" it's subject to change and that
change only you (the native) can bring. If you are seeking "remedies or
pariharams" to nullify any malefic influence, they do not exist in Jyotish
scriptures.
