In my astrological journey of two decades, I find the misconceptions and fears about Mangal Dosha have created too much confusion. I am constrained to blame even the astrologers who, without knowing or revealing the actual facts, blot a person with Manglik Dosha and, more surprisingly, drift the natives towards unrealistic rituals and remedies.
There is no doubt that the Mangal dosha can cause issues related to marriage matters, but how to check, if you are really Manglik. There are calculators/ other free tools available to check Mangal dosha, but if someone checks such a critical point with a little care, 75% of people will be relieved.
