Emil Bock: "One can be brought by these pictures [in the gospel of Luke] to a spiritual recognition of the secret of Mary, to the discovery of a mystery of the Madonna in every individual human soul. Let us take as an example the meeting of Mary and Elizabeth. This picture becomes one through which all human meetings can be hallowed. Everyone has a soul in which, as in a mother's womb, the spiritual ego rests and germinates--the true human being of every individual, which has not yet been able to break forth. What higher thing could be wrought in one person by another than that the spiritual embryo of one should arouse the spiritual embryo in another's soul, so that it leaps in joy, so that in that person, as in Elizabeth, the hope of future evolving awakens. Just such a picture as that of the two mothers can bring to our awareness how often people touch only the surface in their meeting instead of awakening and animating the center of life itself. Every meeting may be an awakening, an awakening of the secret of Mary in the soul."
