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.

True peace of mind comes from accepting the worst.

[P]eace of soul implies tranquillity of order, with material things ordered to the body, the body to the soul, the personality to neighbor and to God. Peace of mind is subjective tranquillity — a narrower thing. It requires great moral effort to attain peace of soul, but even those who are indifferent to right and wrong sometimes achieve peace of mind (which the Scriptures call "false peace").

Of vast importance in achieving peace of mind is dealing with the contents of mind itself: the mass of all ill thoughts you have stored up over the years, all the regrets, all the futilities, all the hidden sins, all the hates, all the grudges, all the vindictiveness. The minds of many people are filled with pockets of poison.

Peace of mind comes from not wanting to change others.

The very basis of true peace of mind is a benevolent wish to see all the world as happy as one's Self; and from my soul do I pity the selfish churl, who, remembering the little bickerings of anger, envy, and fifty other disagreeables to which frail mortality is subject, would wish to revenge the affront which pride whispers him he has received.

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 the most important and work.

(…) there is no such thing as peace of mind. Mind means disturbance; restlessness itself is mind.(…) Examine closely and you will see that the mind is seething with thoughts. It may occasionally go blank, but it does it for a time and reverts to its usual restlessness. (...).

To have peace of mind, you have to have peace of body first.

it will be helpful to keep the following underlying themes in mind: Peace of mind is our single goal. Forgiveness is our single function and the way to achieve our goal of peace of mind. Through forgiveness, we can learn not to judge others and to see everyone, including ourselves, as guiltless.

...peace of mind: Thou shalt have it only, the answer seemed to come to me, when thou has ceased to desire it.

By a tranquil mind I mean nothing else than a mind well ordered.

In making practical application of the material covered in this book to everyday solutions, it will be helpful to keep the following underlying themes in mind: Peace of mind is our single goal. Forgiveness is our single function and the way to achieve our goal of peace of mind. Through forgiveness, we can learn not to judge others and to see everyone, including ourselves, as guiltless. We can let go of fear when we stop judging and stop projecting the past into the future, and live only in the now. We can learn to accept direction from our inner intuitive voice, which is our guide to knowing. After our inner voice gives us direction, it will also provide the means for accomplishing whatever is necessary. In following one’s inner guidance, it is frequently necessary to make a commitment to a specific goal even when the means for achieving it are not immediately apparent. This is a reversal of the customary logic of the world, and can be thought of as “putting the cart before the horse.” We do have a choice in determining what we perceive and the feelings we experience. Through retraining of the mind we can learn to use positive active imagination. Positive active imagination enables us to develop positive, loving motion pictures in our minds.
