A great inspirational resource is The Archive for Research in Archetypal Symbolism (ARAS.org.) C.G. Jung started it as a collection of archetypal symbols to stimulate the collective unconscious. They published a Book of Symbols that is one of my most beloved books*. I posted a few pics from my own to sample what it looks like.
I really recommend following their Facebook and signing up for their newsletters, probably, the only email newsletter, I actually read. They usually post groupings of 3 images like: bone, woman, bee, etc; that are just gorgeous.
Acquiring their desktop calendar is on my “to do.”
*But is there was a fire, the only book I’d grab is my well worn copy of Even Cowgirls Get the Blues.
