There is nothing which occasions so diligent a search for God as does desolation; neither is there anything that attracts God to the heart so much as desolation, since the acts of conformity to the divine will which are made in desolation are more pure and perfect than others; and hence, the greater the desolation, the greater is the humility, the purer is the resignation, the purer is the confidence, the purer are the prayers, and so the more abundant are the divine graces and assistances.
--St. Alphonsus Liguori, The Way of Salvation and Perfection
