If "Becoming conscious only creates more shadow" were true, Jung would have been the creepiest man in history. I assure you, from studying his work for 25 years, he was not. In fact, he was one of the most balanced and insightful people in history. Sadly, you have missed the point catastrophically.
"Who/what/where/when/why/how" is the logic of journalism, not of Jung. Jung spent his entire professional life teaching us the "how." The circular logic is yours, not his.
You offer no explanation as to why consciousness creates shadow.
"Is there special content that doesn't create a shadow?"
Knowledge of the shadow does not create shadow; it lessens it. This is the only critical feedback I have at this point for your responses.
