Surely the most deeply-rooted need of the human soul, its purest aspiration, is for the closest possible union with God. As one turns over the pages of this little work, written by Blessed Albert the Great1 towards the end of his life, when that great soul had ripened and matured, one feels that here indeed is the ideal of one's hopes. Simply and clearly the great principles are laid down, the way is made plain which leads to the highest spiritual life. It seems as though, while one reads, the mists of earth vanish and the snowy summits appear of the mountains of God. We breathe only the pure atmosphere of prayer, peace, and love, and the one great fact of the universe, the Divine Presence, is felt and realized without effort.
