Living on the surface of the earth sense impressions constrain
us to regard the earth as flat and still, and the sun and other
heavenly bodies as moving across the heavens above our heads.
But astronomers know that by long watching of the heavenly
bodies an observer comes often to feel the motion and sense the
rotundity of the earth.
So of the man who will live in the spiritual altitudes. He reasonably
believed before in the future life, but all his impressions have been
earthly, materialistic. But on the higher level he actually “lays hold
on the powers of an endless life.”
