is Latin, meaning
spirit or soul of the world -
the spirit or soul of the universe
with which all individual souls are connected
through the 'Great Memory,'
which Yeats held to be a universal subconscious
in which the human race preserves its past memories.
It is thus a source of symbolic images for the poet.
Counterparts for the Garou include the Past Life background,
and the Umbra and its denizens.
