Strength is not gained by shaming your humanity.
It's gained by fully looking at all the judgments you have about it, and turning towards self-inquiry and seeing why judgment towards yourself feels good...why do we choose this, and what/who does it serve?
Shame is a trauma wound.
Superiority and "gaining tools" are coping strategies.
Looking straight at shame in the face and loving it despite the faces it will show you, is the most courageous spiritual work we will ever do, whether inside ourselves as our inner dialog or outside ourselves as fellow humans.
