Being a Manglik is not such a bad thing. In fact Mars in the 7th indicate increased sexual potency and this could sometimes be incompatible with a person who has less interest in such matters which in the olden days could lead to dystrophy or tuberculosis. Modern medicines can easily overcome such situations. In fact the fearsome attributes of being a Manglik are ill founded and it is only a myth or misconception in Astrology promoted by astrologers who are not well initiated into the essence of astrology.
But compatibility in horoscopes is a must and for that it must be properly analysed. Read my articles on this site “Astrology – A new Version” or read my blog at http://navagrahastro.blogspot.in/.
