Above all, it is not necessary that we should have any unexpected, extraordinary experiences in meditation. This can happen, but if it does not, it is not a sign that the meditation period has been useless. Not only at the beginning, but repeatedly, there will be times when we feel a great spiritual dryness and apathy, an aversion, even an inability to meditate. We dare not be balked by such experiences. Above all, we must not allow them to keep us from adhering to our meditation period with great patience and fidelity.Dietrich Bonhoeffer, Life Together, 83-84
....We must center our attention on the Word alone and leave consequences to its action.
