If a man does not control his temper, it is a sad admission that he is not in control of his thoughts.

In any organization, someone must be the boss. If it's even just one person, you've got to be the boss of yourself.

Mankind's history has proved from one era to another that the true criterion of leadership is spiritual. Men are attracted by spirit. By power, men are forced. Love is engendered by spirit. By power, anxieties are created.

It is in your power to withdraw yourself whenever you desire. Perfect tranquility within consists in the good ordering of the mind, the realm of your own.

When force of circumstance upsets your equanimity, lose no time in recovering your self-control, and do not remain out of tune longer than you can help. Habitual recurrence to the harmony will increase your mastery of it.

To the best of my judgment, when I look at the human character I see no virtue placed there to counter justice. But I see one to counter pleasure: self-control.

Nature did not blend things so inextricably that you can't draw your own boundaries—place your own well-being in your own hands. It's quite possible to be a good man without anyone realizing it. Remember that.

If someone asked you how to write your name, would you clench your teeth and spit out the letters one by one? If he lost his temper, would you lose yours as well? Or would you just spell out the individual letters? Remember—your responsibilities can be broken down into individual parts as well. Concentrate on those, and finish the job methodically—without getting stirred up or meeting anger with anger.

When thou hast been compelled by circumstances to be disturbed in a manner, quickly return to thyself, and do not continue out of tune longer than the compulsion lasts; for thou wilt have more mastery over the harmony by continually recurring to it.

You'll find that none of the people who make you lose your temper has done anything that might affect your mind for the worse; and outside of the mind there's nothing that is truly detrimental or harmful for you… After all, you even had the resources, in the form of your ability to think rationally, to appreciate that he was likely to commit that fault, yet you forgot it and are now surprised that he did exactly that.

I will not allow things outside my mind to affect my mind. I will not let external events shake and shatter my inner peace. I will not waste my energy on things outside my control

Your mind is your only strength; your reason is your only power.
