It might seem like an easy matter for a father to arrange his daughter’s marriage, but religion and caste systems make it a daunting task.
A number of factors are considered, for instance, generally speaking, marrying outside of one’s own caste is frowned upon, so that limits the number of choices.
It’s not like the couple see each other on the wedding day for the first time or just once before the wedding. There is usually a period of months or even a year or more after the couple are engaged and before the wedding, where the couple get to know each other, meet, talk and discuss the future.
This time after the engagement to the wedding day is sort of the dating period for the couple.
Also, since the majority of Indians are Hindu, and Hindu’s believe strongly in astrology, the perspective couple’s horoscopes are be analyzed and “suitably matched” or the marriage cannot take place.
