Jettison the judgement, and you are saved. And who is there to prevent this jettison?
To summarize the three thoughts that we have to keep in mind:
One - all actions with an aim and with justice. For those things out of my control, accept it.
Two - memento mori we all will die; and it could be at any time. We cannot take our mind off this thought.
Three - divide to despise; all these things in the world are so small and petty compared to the grand universe. The idea is to keep in mind how small all of us and all things are - it puts problems and issues we face, into perspective.
In chapter 25 of Book 12, Marcus reminds us that our opinion shapes our world view. And we have complete control over our own opinion.
