So dazzling you have to avert your eyes 
Behind your closed eyelids, an afterimage
مبهر جدًا لدرجة أنّه عليك الإشاحة بنظرك
خلف جفنيك المغمضين، صورة تِلويّة
So blendend hell, dass du deine Augen abwenden musst
und ein Phantombild hinter geschlossenen Lidern siehst.
Così abbagliante da dover distogliere lo sguardo
Dietro le palpebre chiuse, un'immagine residua
Tão ofuscante que desvia o olhar. Atrás das
pálpebras fechadas, uma imagem residual
Так глаза слепит, даже
за закрытыми глазами вижу сияние.
