Thomas a' Kempis
“Love is swift, sincere, kind, pleasant, and delightful. Love is strong, patient and faithful, prudent, long-suffering, and manly. Love is never self-seeking, for in whatever a person seeks himself there he falls from love. Love is circumspect, humble, and upright. It is neither soft nor light, nor intent upon vain things. It is sober and chaste, firm and quiet, guarded in all the senses. Love is subject and obedient to superiors. It is mean and contemptible in its own eyes, devoted and thankful to God; always trusting and hoping in Him even when He is distasteful to it, for there is no living in love without sorrow. He who is not ready to suffer all things and to stand resigned to the will of the Beloved is not worthy to be called a lover. A lover must embrace willingly all that is difficult and bitter for the sake of the Beloved, and he should not turn away from Him because of adversities.”
