If you have inner peace, nobody can force you to be a slave to the outer reality.
The serenity of mind, gentleness, silence, self-restraint, and the purity of mind are called the austerity of thought.
The life of inner peace, being harmonious and without stress, is the easiest type of existence.
The pursuit, even of the best things, ought to be calm and tranquil.
Serenity comes when you trade expectations for acceptance.
Peace is the result of retraining your mind to process life as it is, rather than as you think it should be.

Serenity is not freedom from the storm, but peace amid the storm.
God, grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference.

Calmness of mind is one of the beautiful jewels of wisdom.
True silence is the rest of the mind, and is to the spirit what sleep is to the body, nourishment and refreshment.
The only Zen you find on the tops of mountains is the Zen you bring up there.
Life is full of noise and chaos. The trick is to find the stillness within.
The greatest self is a peaceful smile, that always sees the world smiling back.

Learn to be calm and you will always be happy.

In the midst of movement and chaos, keep stillness inside of you.
The key to serenity is trusting that the universe has your back.
Happiness is not something ready-made. It comes from your own actions.
