But as for Aslan himself, the Beavers and the children didn't know what to do or say when they saw him. People who have not been in Narnia sometimes think that a thing cannot be good and terrible at the same time. If the children had ever thought so, they were cured of it now. For when they tried to look at Aslan's face they just caught a glimpse of the golden mane and the great, royal, solemn, overwhelming eyes; and then they found they couldn't look at him and went all trembly.
