That's a spiritual lifestyle, being willing to admit that you don't know everything and that you were wrong about some things. It's about making a list of all the people you've harmed, either emotionally or physically or financially, and going back and making amends. That's a spiritual lifestyle. It's not a fluffy ethereal concept.
I also believe that forgiveness is appropriate only when parents do something to earn it. Toxic parents, especially the more abusive ones, need to acknowledge what happened, take responsibility, and show a willingness to make amends. If you unilaterally absolve parents who continue to treat you badly, who deny much of your reality and feelings, and who continue to project blame onto you, you may seriously impede the emotional work you need to do.
