Merriam-Webster definition for discernment =
Discernment is not about judging really, especially not judging a person. It is about deciding if you choose to incorporate or assimilate what is being given to you and choosing the framework you will receive it in.
It is being willing to hear yourself and trusting in your ability to have clear and correct opinions as to what is healthy or acceptable to you.
Many of us have this ability squashed out of us as we are told that we do not know what we think or feel, often by those that we should be able to trust. And it is often done by when we are in a vulnerable position. If done early enough and long enough when we are young we will accept that as a fact even once we are older and on our own, not unlike the elephant who having been trained as a little fellow will not pull away from the chain he could easily break as an adult.
We need to take this capacity back. It is vital to our ability to be free.
