Though the path is plain and smooth for men of good will, he who walks it will not travel far, and will do so only with difficulty, if he does not have good feet: that is, courage and a persevering spirit.
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 CrossThe eternal spring is hidden in this living bread for our life's sake, although it is night. It is here calling out to creatures; and they satisfy their thirst, although in darkness, because it is night. This living spring that I long for, I see in this bread of life, although it is night.
John of the Cross
