If your mars is in 1st,4th,7th,8th or 12th house then You are Manglik.This is not a big deal as approx 50% of our population has Manglik Dosha.What you need to understand is the nature of your mars and how strong or weak your mars is.If you are Manglik from Ascendant and Moon chart both then your Manglik effect will be increased from 50% to 75%.All you need to know how to divert your Marsian strength or energy that I wrote on ‘Remedy for Mars’ few days back.
Mars in 4th house : 4th house in our chart represents Domestic happiness,Family Life,mental peace,property,Basic education, your personal space,duty towards society etc.This is the natural house of Cancer ruled by Moon where Mars gets debilitated.so a fiery planet like mars gets posited in 4th house that brings unnecessary clash in physchological approach and emotionally black time to time.People with mars in 4th house want to be all in one in their family.Thats when the clash starts with partner and a person ends up losing domestic happiness.If the partner is not having similer personality it gets hard to handle such pushy nature hence most of the time misunderstanding in family.In 4th house Mars loses his strength for direction and creates more trouble in family life.From here Mars will cast his 4th aspect on the 7th house of spouse and marital life.
It may arouse jealousy with brothers/sisters which may be due to wife/husband.If well placed it gives a lot of property.
There may be trouble related to stomach and property losses through theft, fraud and quarrels.
There will also be a tendency for extra-marital affairs(if afflicted).
If afflicted by Saturn, Rahu or Ketu, this placement can cause a sudden Accidental issues.
For Cancer and Leo Ascendant Mars doesnt give bad effect for being yoga karak planet.For Aries,Taurus,Gemini,Virgo,Saggi,Pisces Ascendant Mars in 4th house can play a havoc in marital life if no benefic aspects on it or if no cancellation of Manglik Dosha.According to me no factors can 100% nullify the effect of Manglik Dosha only can reduce the adverse effect upto 50%.Easiest and more Logical Way of nullifying of Manglik Dosha and its adverse effects is to get married to another who has similar position of Mars.
It has to be remembered that it is not only Mars that can create problem in married Life, but there are lot of other factors which can disturb marital happiness. So its not fair to blame every time Manglik People for marital disturbance.
Wearing Mars-stone to avoid Mangalik influence is also a wrong practice running in our society, as wearing Mars-stone will increase the reception of the vibrations of Mars and consequently the qualities caused by Mars will also increase instead of decreasing.One can rather opt for Mars Remedy to get little relief from Manglik effect in life.
