John of the Cross Quote

If the soul has not reached the state of unitive love, it is necessary for it to make acts of love, as well in the active as in the contemplative life. But when it has reached it, it is not requisite it should occupy itself in other and exterior duties — unless they be matters of obligation — which might hinder, were it but for a moment, the life of love in God, though they may minister greatly to His service; because an instant of pure love is more precious in the eyes of God and the soul, and more profitable to the Church, than all other good works together, though it may seem as if nothing were done.
