Love is something melodious feeling which we have in our life.
It is not necessary a person must love an opposite gender but may love any nonliving thing.
Sometimes people love cats and dogs. Some people love deers to have at home.
I have read in a book that a person was much interesting .
He never married in his life because he was addicted to books .
He used to say that I have books which make me learn. I have no time for a lady to waste with her in my room. Laugh out loud.
Being a man it is our urge to choose someone special to spend our whole life with that person. It may prove good for us. Man has natural process called sex and that can be achieved by a proper and lovely partner. This may result in beautiful children in his life.
It was said by saints and intellectuals that God Poured himself to the earth in the form of love.
In fact, love is a very strange thing that cannot be seen or touched but its presence can be felt. The meaning of love is different for each person and different for each person. In my opinion, love is a complex thing, so it is better not to worry about it.
