Yes, the change is how to accept reality downwhim.
For example. My father is narcissistic. Caused great pain for 40 years because I kept trying to get attention and was invalidated. He has difficulties showing love. A tall order for a man that's narcissistic, yet my pain was that I felt invalidated, unloved, rejected and unwanted.
I radically accepted the man for whom he is. He does not have the capacity to change when I wished he would change. He is who he is. I accept that. The anxiety, stress and pain associated with that alleviated.
You can apply it in any situation. He's a parent. I had to accept my ex the same way. I radically accept that she is a person that is limited with the capacity to change. She's a difficult personality and I can't change these circumstances.
“Imperfection is not our personal problem - it is a natural part of existing.”― Tara Brach, Radical Acceptance: Embracing Your Life With the Heart of a Buddh
Accepting reality for what it is. Flowing with reality instead of flowing against it, flowing against it causes the anxiety, stress, pain, suffering.
My father, my wife caused me much suffering and it was letting go of the fact that two loved ones are mentally ill. It is not personal.
It is what it is. They are whom they are.
Accepting this reality. I still love my father. I care for my ex as she is the mother of my children.
“The boundary to what we can accept is the boundary to our freedom.”― Tara Brach, Radical Acceptance: Embracing Your Life With the Heart of a Buddha
I set boundaries to keep the bad stuff out and the good stuff in. I'm indifferent to both.
Life has imperfections in it and is a part of life. It's accepting their imperfection, mental illness and disorders as their conditions are not personal
to me. It can be a goal, it is not easy - the key is practice.
I hope that helps.
