"Then my realities; What else is so real as mine? Libertad and the divine average, freedom to every slave on the face of the earth, The rapt promises and lumine of seers, the spiritual world, these centuries-lasting songs, And our visions, the visions of poets, the most solid announcements of any."
January 1, 1970
