In answer to more personal inquiries from the deeply-interested Guibert, Hildegard (who at the time was venerable in years and in repute for sanctity) explains how she saw her visions, and how her knowledge of Scripture came to her:

“From infancy, even to the present time when I am more than seventy years old, my soul has always beheld this visio,[557] and in it my soul, as God may will, soars to the summit of the firmament and into a different air, and diffuses itself among divers peoples, however remote they may be. Therefore I perceive these matters in my soul, as if I saw them through dissolving views of clouds and other objects. I do not hear them with my outer ears, nor do I perceive them by the cogitations of my heart, or by any collaboration of my five senses; but only in my soul, my eyes open, and not sightless as in a trance; wide awake, whether by day or night, I see these things. And I am perpetually bound by my infirmities and with pains so severe as to threaten death, but hitherto God has raised me up.

“The brightness which I see is not limited in space, and is more brilliant than the luminous air around the sun, nor can I estimate its height or length or breadth. Its name, which has been given me, is Shade of the living light (umbra viventis luminis). Just as sun, moon, or stars appear reflected in the water, I see Scripture, discourses, virtues and human actions shining in it.

“Whatever I see or learn in this vision, I retain in my memory; and as I may have seen or heard it, I recall it to mind, and at once see, hear, know; in an instant I learn whatever I know. On the other hand, what I do not see, that I do not know, because I am unlearned; but I have had some simple instruction in letters. I write whatever I see and hear in the vision, nor do I set down any other words, but tell my message in the rude Latin words which I read in the vision. For I am not instructed in the vision to write as the learned write; and the words in the vision are not as words sounding from a human mouth, but as flashing flame and as a cloud moving in clear air.

“Nor have I been able to perceive the form of this brightness, just as I cannot perfectly see the disk of the Sun. In that brightness I sometimes see another light, for which the name Lux vivens has been given me. When and how I see it I cannot tell; but sometimes when I see it, all sadness and pain is lifted from me, and then I have the ways of a simple girl and not those of an old woman.”[558]

The obscure Latin of this letter gives the impression of one trying to put in words what was unintelligible to the writer. And the same sense of struggle with the inadequacies of speech comes from the prologue of a work written many years before:

“Lo, in the forty-third year of my temporal course, while I, in fear and trembling, was intent upon the celestial vision, I saw a great splendour in which was a voice speaking to me from heaven: Frail creature, dust of the dust, speak and write what thou seest and hearest. But because that thou art timid of speech and unskilled in writing, speak and write these things not according to human utterance nor human understanding of composition; but as thou seest and hearest in the heavens above, in the marvels of God, so declare, as a hearer sets forth the words of his preceptor, preserving the fashion of his speech, under his will, his guidance and his command. Thus thou, O man (homo), tell those things which thou seest and hearest, and write, not according to thyself or other human being, but according to the will of Him who knows and sees and disposes all things in the secrets of His mysteries.

“And again, I heard a voice saying to me from heaven: Tell these marvels and write them, taught in this way, and say: It happened in the year one thousand one hundred and forty-one of the incarnation of Jesus Christ the Son of God, when I was forty-two years old, that a flashing fire of light from the clear sky transfused my brain, my heart, and my whole breast as with flame; yet it did not burn but only warmed me, as the sun warms an object upon which it sheds its rays. And suddenly I had intelligence of the full meaning of the Psalter, the Gospels, and the other books of the Old and New Testaments, although I did not have the exact interpretation of the words of their text, nor the division of syllables nor knowledge of cases and moods.”

The writer continues with the statement:

“The visions which I saw, I did not perceive in dreams or sleeping, nor in delirium, nor with the corporeal ears and eyes of the outer man; but watchful and intent in mind I received them according to the will of God.”[559]
