He who loses an opportunity is like the man who lets a bird fly from his hand, for he will never recover it.
John of the CrossThe centre of the soul is God; and, when the soul has attained to Him according to the whole capacity of its being, which is the strength and virtue of the soul, it will have reached the last and the deep centre of the soul, which will be when with all its powers it loves and understands and enjoys God.
John of the CrossFor true devotion must issue from the heart, and consist in the truth and substances alone of what is represented by spiritual things; all the rest is affection and attachment proceeding from imperfection; and in order that one may pass to any kind of perfection it is necessary for such desires to be killed.
