  the sun shines so strongly that it stings people in the eyes.” (Source: Kupsabiny Back Translation)
• Newari: “No one is able to look now
  at the brightness of the sun
  that is in a sky that the wind has made clear.” (Source: Newari Back Translation)
• Hiligaynon: “There is no man who can-look-at the sun for it shines brightly in heavens if the wind-clears away the clouds.” (Source: Hiligaynon Back Translation)
• English: “Now, people cannot look directly at the sun
  when it shines brightly in the sky after the wind has blown the clouds away;
  so, we certainly cannot look at the brightness of God.” (Source: Translation for Translators)
