"A gun is used by an army man and a gun is also used by a terrorist. The gun shoot of a person is for his good, but the terrorist uses the gun for an evil purpose. Army men may use a gun to shoot the enemies and a terrorist may use a gun to destroy nation. If all the guns are put in a circle with a magnet at the centre, all the guns will be equally attracted by the magnet. The good or the bad is not in the guns. Actually it is in our mind. It lives into our mind. We need to change our attitude of thinking only.
