Nowadays, it is held by many people that one should not marry without love. A man and a woman may freely make friends with each other. They do not talk of marriage until their friendship has ripened into love. In their marriage, they may take other things into consideration, but they regard love as the most important thing. This type of marriage usually brings happiness.
Moreover, love may be a temporary passion, and those who are in love are often blind to other things, so that what we call love matches do not always result in happiness. Therefore, while love is required before a marriage is arranged, it is not the only thing required.
