It is true that love knows no caste but when it comes to marriage, there are certain caste restrictions in our society and which is why marriages between persons of different castes are not favored. However, now the times have changed and as a result of education and progress the attitude towards inter caste marriage has softened especially in cities.
But it must be noted that Vedic astrology also suggests that one take some astrological measures before opting for inter caste marriage. Astrological consultation can reveal the compatibility of the couple and the chances of a successful marriage.
Simple horoscope analysis of the boy and girl can tell much about their future together. For instance, the fifth and seventh house in a birth chart represent love and romance and spouse respectively and a favorable relationship between these two houses and placement of Venus in case of male or Mars in case of female improves the chances of success in any marriage. There are other analyses which can reveal further about the marriage. Pandit ji is an expert astrologer who has guided many couples to happy marriages and is a well known astrologer for inter caste marriage related consultation.
