From a physiological perspective
it is at least possible,
that waking consciousness
is merely a phenomena of release
from the higher-state of dream consciousness.
Intuitively recognising this,
ancient man, as opposed to modern man,
existed in a vast living universe,
as a deliberately created being of the cosmos,
rather than as an accident of birth in an indifferent world.
Consequently, not only did ancient man inhabit the world,
but the world also lived within him.
