Have a great love for those who contradict and fail to love you, for in this way love is begotten in a heart that has no love.
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.
John of the Cross
