So ugly or unattractive people should stay celibate all their lives or they should go and live in a jungle ?
My observation is that I have seen the best looking girls/boys married and deeply in love with their not so pretty/handsome looking spouses. Be it love or arranged marriage , looks do not matter what matter is the love , harmony , chemistry, accommodating/compromising nature, understanding , sacrifices to keep each other happy.
You do not marry a pretty/handsome face or body , you marry a complete human being , a complete personality.
In desi culture it is always said that "it is a marriage of two families not a marriage of just two human beings."
