Beauty as we feel it is something indescribable: what it is or what it means can never be said.

Our reading
An editorial interpretation.
The feeling of beauty can't really be pinned down in words. We know it when we experience it, but explaining exactly what it is or what it means always falls short. The speaker treats beauty as something felt directly rather than defined.
