Love is the only thing that is eternal. But it should be unconditional, it should be pure love. it must be unlimited and lawless. if you love those who love you, there is no virtue in it. But there is vice in it. love is what everyone looks for.. everybody is happy when he loves. When he is loved he is rather happy. Love can be of different types, heavenly love, erotic love and energetic love. conjugal love is still deeper and eternal.
