We are what we think. All that we are arises with our thoughts. With our thoughts, we make the world.

Anger will never disappear so long as thoughts of resentment are cherished in the mind.

Those who are free of resentful thoughts surely find peace.

All that we are is the result of what we have thought: it is founded on our thoughts and made up of our thoughts. If a man speak or act with an evil thought, suffering follows him as the wheel follows the hoof of the beast that draws the wagon.... If a man speak or act with a good thought, happiness follows him like a shadow that never leaves him.

The way to chastity is not to struggle directly with incontinent thoughts but to avert the thoughts by some imployment, or by reading, or meditating on other things.

The highest possible stage in moral culture is when we recognise that we ought to control our thoughts.
