You reminded me of a colleague who worked with Jung's Shadow Theory in the field of psychoanalysis, mostly for a phrase he liked very much: "The brighter the light is the more fierce the shadows of it are. which is illuminated "

I also remember a little bit what he told me about the story of how Jung came up with the basis of this theory for a dream, in which he walked holding a candle before him and protected it from the wind, but he felt something following him and He felt a little afraid, turned to see and found his immense shadow projected behind him, upon waking he thought that the light was equivalent to his reason, he was the Person or Mask that is shown before everyone and his Shadow was the subconscious and hidden part that we always have, it can be scary and we can try not to accept it, but it will always be there while the light of reason is on.
