Terms or expressions mostly trace the origin of their
inner symbolism to the inner self, which mingles with
spirits and angels. In every one of us, the spirit, or the
actual person that survives the body’s death, lives in
community with angels and spirits, even though our
outer self is unaware of it. Because our inner self lives in
community with angels and spirits, along with them it
also has access to the universal language and therefore to
the origins of words.
