I agree with you, coming to actual realizations of that truth could propel you ever forward, breaking all illusions of bondage.
However, that path is the least tread upon, letting go of that identity that one has spent a lifetime building is not something that appeals to everyone, all those accolades and accomplishments, the empires, the bellies you’ve stomped to get them, the homeless you’ve spit on their face, the sacrifices, all in vain, its actually terrifying to ponder upon, until you take that deep dive and realize you can still breathe.
In the world of duality, the poles are always dancing and rhythmically flowing; right/wrong, black/white - yin ‘n yang (album droppin’ soon) your shadow’s there, patiently waiting in the dark for its that hand tap to jump into the ring, and vice versa; and the wheel thus goes one, until you say “okay, screw both of y’all, I’m done with both of you”. Its like you’re 50% ego and 50% not (in a great stable case).
Be that as it may, working on your shadow, even though its born of trauma and all the ego is but trauma, is not such a bad idea. I see it as a stepping stone, although, in my opinion there’s a ceiling limit at some point on either extreme cases of that polar, and from my own experience, the further you go in either direction (more good than bad, or more bad than good, as if walking towards one side and having a larger distance to the other), the fall back is not going to be pleasant. You could see cases of extreme Psychopathic, Narcissistic, Sadistic, Machiavellianism, just truly awful people, completely inhuman (using extremes for the purpose of clarifying) suddenly turn around and become saintlike, and vice versa.
Nonetheless, its another step forward rather than remaining still in the starting point, and if more folks do that kind of healing it will be worth it. Do your healing, and if you got a rude awakening at some point in your life, don’t just go back to slumber and remember not to glue that mask to your face.
I do apologize in advance if I seemed harsh, rude or insensitive, not my intention to do so
