Love can never really be a great base for marriage because love is fun and play. If you marry someone for love you will be frustrated, because soon the fun is gone, the newness is gone, and boredom sets in. Marriage is for deep friendship, deep intimacy. Love is implied in it, but it is not alone. So marriage is spiritual. It is spiritual. There are many things which you can never develop alone. Even your own growth needs someone to respond, someone so intimate that you can open yourself totally to him or her.
