Just as there is a poison in the sting of the scorpion, and as there is a poison in the teeth of the snake, so there is poison in the heart of man which is made to be the shrine of God. But God cannot arise in the shrine which is as dead by its own poison; it must be purified first and made real for God to arise. The soul who had to sympathize with the whole world was thus prepared, that the drop of that poison which always produces contempt, resentment and ill-feeling against another, was destroyed first. So many talk about the purification of the heart, and so few really know what it is.
