They had to be purified of all hollow notions.

他们必须被净化掉所有空洞的概念。

The Mound is all hollowed out within into galleries and caves, and the Stone is in the central cave of all.

后来，那土丘上挖出了许多甬道和洞穴，那块巨石就放在土丘中心那个洞穴里。

" Many vain people have I seen in my day, but you beat them all hollow" .

“我这一天见过很多虚荣的人， 但你把他们都打得空虚” 。
