My view of the world is entirely up to me.
If I choose to be gloomy, the world will look gloomy.
If I choose to be happy, the world will look happy.
There will always be unpleasant (evil) things in this world, but if I choose to look past them, I realize that they are only a filter.
Some force is trying to keep me from seeing the beauty while another force is trying to show me the beauty.
