It is comment perspective that love marriages in India is a new concept and traditionally there had been only arrange marriages in India.
However, I disagree with it. There are many examples like: Marriage of Lord Krishna and Rukmani, marriage of Arjun and Subhadra, Marriage of Shakuntala and Dushant, marriage of Prithviraj and Sanyogita and so on... It shows that there had not always been "arrange marriages".
Its true that now especially in urban areas, mostly love marriages are preferred but there are exceptions too.
Marriage is a bond with reponsibility for the life time. For many people, that bond is for 7 janams. If that bond is of love and trust, than marriage is a bliss...but if there is doubt, mistrust, not understanding the feelings of your life partner, than it can become curse and make the life hell too !
Therefore I think true love, respect and trust is essential whether its arrange marriage or love marriage.
