Love is a unifying virtue which takes upon itself the torments of its beloved Lord. It is a fire reaching through to the inmost soul. It transforms the lover into the one loved. More deeply, love intermingles with grief, and grief with love, and a certain blending of love and grief occurs. They become so united that we can no longer distinguish love from grief nor grief from love. Thus the loving heart rejoices in its sorrow and exults in its grieving love.
Saint Paul of the Cross
