> By not being aware of having a shadow, you declare a part of your personality to be non-existent. Then it enters the kingdom of the non-existent, which swells up and takes on enormous proportions…If you get rid of qualities you don’t like by denying them, you become more and more unaware of what you are, you declare yourself more and more non-existent, and your devils will grow fatter and fatter.
You can't "optimism away" the "negative" emotions. You just bury them, but they continue to live in your system, and find their own ways out eventually.
It's easy to fall into the trap of endless negativity. It's also easy to fall into the trap of toxic positivity, where you refuse to process pain or the "negative" because you're trying so hard to force the positive.
