This is a beautiful post.
Reminds me of an osho quote.
He equated sadness as being the roots of a tree and the branches being happiness. The deeper the roots the taller the tree and the taller the tree the deeper the roots. Signifying the balance of life using sadness and happiness.

I feel as though all trauma is teaching us to enjoy the opposite that much more.

Much like therapy when you accept what happened and surrender to it so to say the more you heal then move on from it and go deeper into self. The more you go deeper into self the more power you have. The more power you have the happier or more at peace you are.
