We should not be distressed by lapses from grace. They may well be necessary. We may have been trying too hard, or have become inflated by what we imagine as our progress in the practice of meditation, so that a sudden fall jerks us back to earth. It is like the game of Snakes and Ladders. In our practice we shall, time and again, slide to the bottom of the snake. As Jesus said, ‘No one, having put their hand to the plough and looking back, is fit for the kingdom of Heaven.’ We plod on!
