Love At First Sight - Right Or Wrong?

There are many facets to love. Some term love as God while some term love as illusion. This means that God is an illusion. Now what is this link? I remember to have read that love is an illusion many a time and also to have read that love is god. But that is really confusing. But I am a firm beliver that there can be no love at first sight. I really doubt who coined this phrase - 'love at first site'. When you see a person of the opposite sex what you see is only the physic. You cannot see the mind of the person. And for love to take place, the minds need to get involved. There cannot be only a physical intimacy which you can term it as love. That would be lust. And if god is love then where is the place for lust? Secondly, as long as you don't know the mind of a person how can you love him/her. It is important that you know the person, try to understand him/her and then only proceed. Moreover, to get into love and to remain their takes time. You need to win the confidence of the opposite person and all these activities need time. This cannot happen overnight. And why overnight, in just a moment? My god! I, personally find this really surprising. Such love is bound to break sooner - i hope this comes false. But I have seen some couples who have fallen in love at first sight - in a moment's time and have broken up faster still. Then what you get is only frustration and depression. Is this the love that anyone seeks?
