In vedic astrology, the position of Mars in a native’s horoscope determines the presence of “Mangal Dosha”. The negative impact of this dosha is typically observed in marriage and life post marriage. The Manglik dosha, which is popularly known as ‘mangli’, is very inauspicious because an afflicted native may remain unmarried throughout his or her life. Mangliks have a lot of fiery energy in themselves which have to be channelized properly to avoid destruction.

When does Manglik dosha happen?

If Mars comes in the Ascendant and in 2nd, 4th, 7th, 8th and 12th house then astrologically the person is considered to have Mangal dosha. It is also known as Bhom dosha, Kuja dosha and Angaraaka dosha. This dosha has greater significance when it comes to marriage because it is one of the most important parameters considered at the time of horoscope matching. A person’s horoscope has to be checked for mangal dosha and compatibility has to be ensured before finalising the marriage.
If Mars is in Ascendant then native will be aggressive and lack politeness. He may have a rigid and vindictive nature under a malefic Mars in Ascendant. If Mars in ascendant then 7th aspect will effect and may destroy the happiness from the life of native. The 7th aspect may cause separation and difference between the native and his or her life partner.
If Mars is in 2nd house, it is also afflicted from Manglik Dosha. Second house is known for the significator of wealth and relation. If Mars placement is there, then it affects the relation of native with his or her family members. Native may face separation from his or her spouse.
The Fourth house Mars provides stable wealth to its native but life becomes difficult. Native may lead to a disturbed married life. Native’s relation with his partner may lead to divorce and separation.
Mars placement in 7th house is considered very harmful for the marital life of the native. One may get an aggressive and unhealthy life partner. Mars may lead to an unethical character and post marital affair of the native.
The 8th house Mars gives immense mental stress. A native suffers from low income and problematic married life. Mars negates the auspiciousness of planets in this house. It just swallows the happiness of a married life.
If Mars placement is in 12th house then it increases the sexual attraction and immoral practice of the native. There is lack of care and sympathy between the couple. The native suffers from hidden genital disease. The native married life is affected due to his ill-health.
There are some planetary combination where Manglik Dosha does not exist and Native is not considered as ‘Manglik’ person. The Manglik dosha effect will be neutralized if the Mars is placed in its own house.
The Manglik dosha effect will be neutralized if Mars is in conjunction or aspected by Moon.
If the Venus is placed as the 12th lord and the Mars is placed in 12th house, then the Manglik dosha effect will be neutralized.
If Jupiter unites together in the Mars, then the Manglik dosha effect will get neutralized.

Remedies:

It is advised that an individual with Manglik dosha should marry a native with Manglik dosha and thus they can avoid mental aggression they may cause frequently in their married life.
Manglik individuals who observe a fast on Friday is considered as an effective remedy. This way the native appeases planet Venus.
Performing Navagraha Aradhana is also considered an effective remedy to minimize the hardship caused by the planet Mars.
Mangliks are advised to marry after the age of 28 because the intensity of the dosha decreases with age.
Kumbh vivah is a kind of marriage which helps in reducing the effect of Manglik dosha. In this type of marriage, the Manglik person has to get married to a tree which nullifies the Mangal dosha.
Fasting on Tuesday also brings down the ill-effect of Manglik dosha. Also, performing Poojas and visiting Hanuman Temples on Tuesday.
