In the chronicles of St. Francis we read that the saint saw in ecstasy a great ladder ascending into heaven, at the top of which stood the Blessed Virgin and by which it was shown him he must ascend to reach heaven. There is another related in the chronicles of St. Dominic. There was an unfortunate heretic near Carcassonne, where St. Dominic was preaching the Rosary, who was possessed by a legion of fifteen thousand devils. These evil spirits were compelled, to their confusion, by the command of our Blessed Lady, to avow many great and consoling truths touching devotion to the Blessed Virgin; and they did this with so much force and so much clearness, that it is impossible to read this authentic account, and the eulogy which the devil made, in spite of himself, of devotion to the most holy Virgin Mary, without shedding tears of joy, however lukewarm we may be in our devotion to her.” (True Devotion to Mary #42-St. Louis De Montfort)
