The relationship of marriage should be bound with friendship, love and caring. Everyone in marriage relationship should think about the importance of another partner. Only living with partners, spending time with each other is not what the marriage means. Marriage is combination of two souls as a result of which two souls combined and being one.
As in the mythological age of Ramayana & Mahabharata brides had the right to choose their own groom. And right of choosing groom by bride is called Swyambar. In this tradition brides have full right to choose groom in any way they please.
However, nowadays in country like Nepal and India, parents choose bride and groom for their sons & daughters. As a result of getting married with him/her chosen by parents may or may not be proven as a successful marriage. There is always room for probability of successful marriage and unsuccessful marriage.
This doesn’t mean that the decision taken by parents is wrong. As Nepali tend to value culture and tradition, they also understand the feelings of parents but first preference should be given to the girl and boy as life is theirs.
