Actually by this photo or you can say an wallpaper, I want to say that world can be divide into two parts which are black and white.  Every thing, object, term, article, image, character have two faces black and white.

        White shows the portion which have some irregularities and some kinds of badness. It indulges with some kind of non respective things, whereas the white face is good one, it is for the good one and whatever feature it has that is good one and every body wants to accept this face only.

            But I want to say by this way that both the faces are equally important and equally needed for the balance for the nature and the human behaviour.  Some time we thought the bad things to do and sometimes we become a good person a think about the good habbits and keen to do something good.

      You can understand in this way also that if there is no evil then how can you know the importance of the good things which provide good effects.
