"The soul, if it wants to reign with Christ in eternal glory, must be polished with hammer and chisel strokes, which the divine Artificer uses to prepare the stones, that is, the chosen souls. What are these hammer and chisel strokes? Darkness, my sister, fears, temptations, sadness of spirit and spiritual fears, which reek like a sickness, and bodily discomfort."
- St Padre Pio, LETTERS
