Ummm i think most of all is RESPECT..
If a person knows about the phenomenon of Giving and taking respect clearly...only then he would be able to called as Human.. He will get to know how to respect relations and that's the most important thing
As far as mertimonial bliss is concerned... we cannot term this with such materialistic objectsI agree with the passage of time ,..people has started believing money to be everything but one cannot buy happiness from dollars...May i know where that market is located in which you can but happiness For successful marriage i agree with Swwet sis understanding is the most important thing....Understanding between two persons helps to develop trust among relation... Love itself starts growing then..... Likeness can be developed at once...But love needs time I had said earlier unsaniyat aur muhabbat main buhat farq hota hay...Jahan aik dosray par aitmaad aur bharoosa ho ga..muhabbat khud he apni konpal se sar nikaal ke iss bay-gharz duniya main pyaar ki khushi aur khushbu phaila day gee...
