Undisturbed calmness of mind is attained by cultivating friendliness towards the happy, compassion for the unhappy, delight in the virtuous and indifference towards the wicked.
Those with indomitable spirit are the real successes in life. If you can so train or condition your mind that you are content regardless of what you have or do not have, and if you can stand the challenge of all your trials and remain calm, that is true happiness.
If an evil man comes and creates a disturbance, you should hold your peace. You must not angrily upbraid his; then he who has come to curse you will merely harm himself.
Since, O Mazda, from the beginning, Thou didst create soul and body; mental power and knowledge and since Thou didst place life within the corporeal body and didst bestow to mankind the power to act, speak and guide, you wished that everyone should choose his or her own faith and path freely.
