Tranquility Is Nothing Else Than The Good

Let Not Your Mind Run On What You Lack As Much As On What You Have Already.

If Any Man Can Convince Me And Bring Home To Me That I Do Not Think Or Act Aright, Gladly Will I Change; For I Search After Truth, By Which Man Never Yet Was Harmed. But He Is Harmed Who Abideth On Still In His Deception And Ignorance.

Retire Into Thyself. The Rational Principle Which Rules Has This Nature, That It Is Content With Itself When It Does What Is Just, And So Secures Tranquility.

Purge Your Mind Of All Aimless And Idle Thoughts, Especially Those That Pry Into The Affairs Of Others Or Wish Them Ill.

Do Not Think That What Is Hard For You To Master Is Humanly Impossible; But If A Thing Is Humanly Possible, Consider It To Be Within Your Reach.
