Derive from the root ar-
which in sanskrit means
"to go", "to set in motion", "to move towards"
“Art breaks open a dimension inaccessible to other experience, a dimension in which human beings, nature, and things no longer stand under the law of the established reality principle...
The encounter with the truth of art happens in the estranging language and images which make perceptible, visible, and audible that which is no longer, or not yet, perceived, said, and heard in everyday life.”
