We shall explain and analyse these words in three ways, first, according to the ordinary mode of the beginner's life--that is to say, the active life, which is necessary to all who would be saved. In the second place, we shall analyse these words by applying them to the inner life, exalted and loving, to which many men arrive by the virtues and by the grace of God. Thirdly, we shall explain them by applying them to the superessential and contemplative life, to which few attain and which few can taste, because of the supreme sublimity of this life. ON THE ACTIVE LIFE CHRIST, the Wisdom of the Father, hath said from the time of Adam and still saith (inwardly, according to His Divinity), to all men, "See"; and this vision is necessary. Now let us observe attentively that for him who wishes to see materially or spiritually, three things are necessary. First, in order that a man may be able to see materially, he must have the external light of heaven, or another natural light, in order that the medium--that is to say, the air across which one sees, may be illuminated. In the second place, he must have the will, that the things which he will see may be reflected in his eyes. Thirdly, he must have the instruments, his eyes, healthy and without flaw, that the material objects may be exactly reflected in them. If a man lacks any one of these three things, his material vision disappears. We shall speak no more of this vision, but of another, spiritual and supernatural, wherein all our blessedness resides.
