Love consists not in feeling great things but in having great detachment and in suffering for the Beloved. The soul that is attached to anything, however much good there may be in it, will not arrive at the liberty of Divine union. For whether it be a strong wire rope or a slender and delicate thread that holds the bird, it matters not, if it really holds it fast; for until the cord be broken, the bird cannot fly.
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.
