Men achieve cheerfulness by moderation in pleasure and by proportion in their life excess and deficiency are apt to fluctuate and cause great changes in the soul. And souls which change over great intervals are neither stable nor cheerful. So one should set one's mind on what is possible and be content with what one has taking little account of those who are admired and envied and not dwelling on them in thought but one should consider the lives of those who are in distress thinking of their grievous sufferings so that what one has and possesses will seem great and enviable and one will cease to suffer in one's soul through the desire for more.

The calm man, having learned how to govern himself, knows how to adapt himself to others; and they, in turn, reverence his spiritual strength, and feel that they can learn of him and rely upon him. The more tranquil a man becomes, the greater is his success, his influence, his power for good.

Live with a steady superiority over life-don't be afraid of misfortune, and do not yearn after happiness; it is, after all, all the same: the bitter doesn't last forever, and the sweet never fills the cup to overflowing. It is enough if you don't freeze in the cold and if thirst and hunger don't claw at your insides. If your back isn't broken, if your feet can walk, if both arms can bend, if both eyes can see, and if both ears can hear, then whom should you envy? And why? Our envy of others devours us most of all.

A man who leads a life of tranquillity and reflection, who is not disturbed at home and meddles not with the affairs of the world, may keep his mind at ease and his thoughts in one even course. But such a man has not been tried. All his Ethical philosophy and his passive virtue might turn out to be idle words, if he were once exposed to the rude realities of human existence.

Cultivate quietness in word, quietness in deed, likewise in speech and gait; and avoid impetuous eagerness, for then the mind will remain steady, and will not be agitated by your eagerness. ... For the mind, seated on high on a quiet throne looking intently towards God, must control the passions, ... so that your quietness may be adorned by good proportion and your bearing may appear something divine.

The strong, calm man is always loved and revered. He is like a shade-giving tree in a thirsty land, or a sheltering rock in a storm. "Who does not love a tranquil heart, a sweet-tempered, balanced life? It does not matter whether it rains or shines, or what changes come to those possessing these blessings, for they are always sweet, serene, and calm. That exquisite poise of character, which we call serenity is the last lesson of culture, the fruitage of the soul. It is precious as wisdom, more to be desired than gold — yea, than even fine gold. How insignificant mere money seeking looks in comparison with a serene life — a life that dwells in the ocean of Truth, beneath the waves, beyond the reach of tempests, in the Eternal Calm!

A man becomes calm in the measure that he understands himself as a thought evolved being, for such knowledge necessitates the understanding of others as the result of thought, and as he develops a right understanding, and sees more and more clearly the internal relations of things by the action of cause and effect he ceases to fuss and fume and worry and grieve, and remains poised, steadfast, serene.

… What about the main thing in life, all its riddles? If you want, I'll spell it out for you right now. Do not pursue what is illusionary -property and position: all that is gained at the expense of your nerves decade after decade, and is confiscated in one fell night. Live with a steady superiority over life -don't be afraid of misfortune, and do not yearn for happiness; it is, after all, all the same: the bitter doesn't last forever, and the sweet never fills the cup to overflowing. It is enough if you don't freeze in the cold and if thirst and hunger don't claw at your insides. If your back isn't broken, if your feet can walk, if both arms can bend, if both eyes can see, if both ears hear, then whom should you envy? And why? Our envy of others devours us most of all. Rub your eyes and purify your heart -and prize above all else in the world those who love you and who wish you well. Do not hurt them or scold them, and never part from any of them in anger; after all, you simply do not know: it may be your last act before your arrest, and that will be how you are imprinted on their memory.

Undisturbed calmness of mind is attained by cultivating friendliness toward the happy, compassion for the unhappy, delight in the virtuous, and indifference toward the wicked.

I have found that the greatest degree of inner tranquility comes from the development of love and compassion. The more we care for the happiness of others, the greater is our own sense of well-being. Cultivating a close, warmhearted feeling for others automatically puts the mind at ease. It is the ultimate source of success in life.

If you keep yourself calm, poised and dignified, [10] if you observe rather than are observed, if you don’t envy people with greater success, don’t let externals disconcert you – if you do all this, what more do you need?

Society and conversation, therefore, are the most powerful remedies for restoring the mind to its tranquillity, if, at any time, it has unfortunately lost it; as well as the best preservatives of that equal and happy temper, which is so necessary to self-satisfaction and enjoyment. Men of retirement and speculation, who are apt to sit brooding at home over either grief or resentment, though they may often have more humanity, more generosity, and a nicer sense of honour, yet seldom possess that equality of temper which is so common among men of the world.

It is to be prayed that the mind be sound in a sound body.
Ask for a brave soul that lacks the fear of death,
which places the length of life last among nature’s blessings,
which is able to bear whatever kind of sufferings,
does not know anger, lusts for nothing and believes
the hardships and savage labors of Hercules better than
the satisfactions, feasts, and feather bed of an Eastern king.
I will reveal what you are able to give yourself;
For certain, the one footpath of a tranquil life lies through virtue.

There is one way, then, in which a man can be free from all anxiety about the fate of his soul - if in life he has abandoned bodily pleasures and adornments, as foreign to his purpose and likely to do more harm than good, and has devoted himself to the pleasures of acquiring knowledge, and so by decking his soul not with a borrowed beauty but with its own - with self-control, and goodness, and courage, and liberality, and truth - has fitted himself to await his journey in the next world.
