"The process which the Kabbalists described as the emanation of divine energy and divine light was also characterized as the unfolding of the divine language. ... They speak of attributes and of spheres of light; but in the same context they speak also of divine names and the letters of which they are composed. ... The elements of the divine language appear as the letters of the Holy Scriptures. Letters and names are not only conventional means of communication. They are far more. Each one of them represents a concentration of energy and expresses a wealth of meaning which cannot be translated, or not fully at least, into human language."
