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 CrossYearning: It needs to hurt in order to be worthy of the word. Otherwise it is just wanting.
John of the CrossSeek in reading and thou shalt find in meditation; knock in prayer and it shall be opened in contemplation.
John of the CrossThe conditions of a solitary bird are five: The first, that it flies to the highest point; The Second, that it does not suffer for company, not even of its own kind; The Third, that it aims its beak to the skies; The Fourth, that it does not have a definite color; The Fifth, that it sings very softly.
