Peace of mind attained only through self-satisfaction in knowing you made the effort to do the best of which you’re capable.

Peace of mind is that mental condition in which you have accepted the worst.

Peace of mind comes from not wanting to change others, but by simply accepting them as they are. True acceptance is always without demands and expectations.

I should be at peace. I have understood. Don't some say that peace comes when you understand? I have understood. I should be at peace. Who said that peace derives from the contemplation of order, order understood, enjoyed, realized without residuum, in joy and truimph, the end of effort?

Amen.

And, thinking of this judgment I would no longer be able to change, I suddenly felt a kind of relief, as if peace could come to me only after the moment when there would be nothing to add and nothing to remove in that arbitrary ledger of misunderstandings, and the galaxies which were gradually reduced to the last tail of the last luminous ray, winding from the sphere of darkness, seemed to bring with them the only possible truth about myself, and I couldn’t wait until all of them, one after the other, had followed this path.

There is but one way to tranquility of mind and happiness, and that is to account no external things thine own, but to commit all to God.

Once you gave up the nervous craving to promote yourself, denigrate others, draw attention to your unique and special qualities, and ensure that you were first in the pecking order, you experienced an immense peace.
