St. Benedict of Nursia ca. 480-547
Hence, brethren, if we wish to reach the very highest point of humility and to arrive speedily at that heavenly exaltation to which ascent is made through the humility of this present life, we must by our ascending actions erect the ladder Jacob saw in his dream, on which Angels appeared to him descending and ascending. By that descent and ascent we must surely understand nothing else than this, that we descend by self-exaltation and ascend by humility. And the ladder thus set up is our life in the world, which the Lord raises up to heaven if our heart is humbled. For we call our body and soul the sides of the ladder, and into these sides our divine vocation has inserted the different steps of humility and discipline we must climb. (Rule of St. Benedict Chap. 7)
