Answer the question at the end by quoting:

Hildegard of Bingen  (German: Hildegard von Bingen; Latin: Hildegardis Bingensis; 1098 - 17 September 1179), also known as Saint Hildegard and Sibyl of the Rhine, was a German Benedictine abbess, writer, composer, philosopher, Christian mystic, visionary, and polymath. She is considered to be the founder of scientific natural history in Germany. Hildegard was elected magistra by her fellow nuns in 1136; she founded the monasteries of Rupertsberg in 1150 and Eibingen in 1165. One of her works as a composer, the Ordo Virtutum, is an early example of liturgical drama and arguably the oldest surviving morality play.
Hildegard said that she first saw "The Shade of the Living Light" at the age of three, and by the age of five she began to understand that she was experiencing visions. She used the term 'visio' to this feature of her experience, and recognized that it was a gift that she could not explain to others. Hildegard explained that she saw all things in the light of God through the five senses: sight, hearing, taste, smell, and touch. Hildegard was hesitant to share her visions, confiding only to Jutta, who in turn told Volmar, Hildegard's tutor and, later, secretary. Throughout her life, she continued to have many visions, and in 1141, at the age of 42, Hildegard received a vision she believed to be an instruction from God, to "write down that which you see and hear." Still hesitant to record her visions, Hildegard became physically ill. The illustrations recorded in the book of Scivias were visions that Hildegard experienced, causing her great suffering and tribulations. In her first theological text, Scivias ("Know the Ways"), Hildegard describes her struggle within:  But I, though I saw and heard these things, refused to write for a long time through doubt and bad opinion and the diversity of human words, not with stubbornness but in the exercise of humility, until, laid low by the scourge of God, I fell upon a bed of sickness; then, compelled at last by many illnesses, and by the witness of a certain noble maiden of good conduct [the nun Richardis von Stade] and of that man whom I had secretly sought and found, as mentioned above, I set my hand to the writing. While I was doing it, I sensed, as I mentioned before, the deep profundity of scriptural exposition; and, raising myself from illness by the strength I received, I brought this work to a close - though just barely - in ten years. (...) And I spoke and wrote these things not by the invention of my heart or that of any other person, but as by the secret mysteries of God I heard and received them in the heavenly places. And again I heard a voice from Heaven saying to me, 'Cry out therefore, and write thus!'  It was between November 1147 and February 1148 at the synod in Trier that Pope Eugenius heard about Hildegard's writings. It was from this that she received Papal approval to document her visions as revelations from the Holy Spirit giving her instant credence.  Before Hildegard's death, a problem arose with the clergy of Mainz. A man buried in Rupertsburg had died after excommunication from the Church. Therefore, the clergy wanted to remove his body from the sacred ground. Hildegard did not accept this idea, replying that it was a sin and that the man had been reconciled to the church at the time of his death.  On 17 September 1179, when Hildegard died, her sisters claimed they saw two streams of light appear in the skies and cross over the room where she was dying.

Hildegard explained that she saw all things in the light of God through the five senses:

IN: Celtic Frost () were a Swiss heavy metal band from Zurich. They are known for their strong influence on the development of extreme metal. Formed in 1982 as Hellhammer, the band became Celtic Frost in 1984 and was active until 1993. It re-formed in 2001 and disbanded following frontman Tom Gabriel Fischer's departure in 2008.

Celtic Frost's frontman, guitarist and singer Tom Gabriel Fischer, adopted the alias Tom Warrior. With Steve Warrior on bass, he formed one of the earliest extreme metal bands, Hellhammer, in 1981. Steve Warrior was later replaced by Martin Eric Ain - also a pseudonym. The band attracted a small international fan-base, got signed to Noise Records in Germany and recorded their debut EP Apocalyptic Raids in March 1984, now a rare find on eBay or second-hand record stores around the world.  Metal publications were also skeptical of Hellhammer's musical endeavor. Metal Forces loathed the group; that started a long-lasting feud between that zine and Warrior, which kept Celtic Frost from playing in England for a couple of years. Rock Power was not fond of Hellhammer either - they considered it "the most terrible, abhorrent, and atrocious thing 'musicians' were ever allowed to record". In fact, they were "receiving miserable reviews everywhere", Warrior concluded.  Regarding the controversial status of his former band, Thomas said:  Way back in 1984 and 85, when Martin Eric Ain and I recorded Celtic Frost's first two albums Morbid Tales and To Mega Therion, Hellhammer lasted on us almost like a curse. Even though Hellhammer was the very reason we had thought over our goals and conceived the Frost, HH's left-overs kept being mighty rocks in our way. Many voices saw Frost as the same band with just a name-change. The lack of musical quality in HH made it almost impossible for us to get an unbiased reaction for Frost. To make a long story short, it almost killed all our work and dreams.  By May 1984, Hellhammer had disbanded. Fischer and Ain, along with session drummer Stephen Priestly, regrouped as Celtic Frost. Their 1984 debut mini-LP, Morbid Tales was a hit in the underground metal scene, and the band set out on its first tour, through Germany and Austria. This was followed with an EP Emperor's Return. Both early releases are now available on the one CD.
