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 CrossNever relax, for you will not attain to the possession of true spiritual delights if first you do not learn to deny your every desire.
John of the CrossWould that men might come at last to see that it is quite impossible to reach the thicket of the riches and wisdom of God except by first entering the thicket of much suffering, in such a way that the soul finds there its consolation and desire. The soul that longs for divine wisdom chooses first, and in truth, to enter the thicket of the cross.
