So this is what I know:
Peace is paramount. The basis for all else.
If an action gives no peace, change the action – or change the thought about it.
If a thought gives no peace, stop it – move the focus to another thought. Get some better energy in your mind. The no peace-thought can wait a bit. Don’t worry. You will come back to it. You just need to rest. Everybody is allowed that, right?
When you feel enough good energy from that move, then – and only then – go back and confront the un-peaceful thoughts. Try to change it. Deconstruct it. Counter it.
Go back to it. If it is still there…
