"There is a thinking in primordial images--
in symbols which are older than historical man,
which have been ingrained in him from earliest times,
and, eternally living, outlasting all generations,
still make up the groundwork of the human psyche.
It is only possible to live the fullest life when we are in harmony with these symbols;
wisdom is a return to them.
It is neither a question of belief nor of knowledge,
but of the agreement of our thinking with the primordial images of the unconscious.
They are the source of all our conscious thoughts,
and one of these primordial thoughts is the idea of life after death....
They are indispensable conditions of the imagination;
they are primary data."
--C.G. Jung, Modern Man in Search of Soul
