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.

Calmness of mind is one of the beautiful jewels of wisdom. It is the result of long and patient effort in self-control. Its presence is an indication of ripened experience, and of a more than ordinary knowledge of the laws and operations of thought.

Man becomes whole, integrated, calm, fertile, and happy when (and only when) the process of individuation is complete, when the conscious and the unconscious have learned to live at peace and to complement one another.

Our capacity for calm ultimately depends on our levels of expectation: if we suppose that most things normally turn out to be slightly disappointing (but that this is OK); that change occurs slowly (but that life is long); that most people are neither terribly good nor very wicked (and this includes us); that humanity has faced crisis after crisis (yet muddled through) – if we are able to keep these entirely obvious but highly fugitive thoughts alive in our minds, then we stand to be less easily seduced into panic.

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 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.

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.

The mind is in its own nature when it is calm. The moment you can calm it, that [very] moment you will know the truth.

Calmness among chaos is a sign of emotional maturity.

To be calm when you've found something going on

A man who is at peace with himself is less likely to turn into an extremist or a terrorist.

Be calm. A man can do but little. Enough if that little be right.

Men achieve tranquillity through moderation in pleasure and through the symmetry of life. Want and superfluity are apt to upset them and to cause great perturbations in the soul. The souls that are rent by violent conflicts are neither stable nor tranquil. One should therefore set his mind upon the things that are within his power, and be content with his opportunities, nor let his memory dwell very long on the envied and admired of men, nor idly sit and dream of them. Rather, he should contemplate the lives of those who suffer hardship, and vividly bring to mind their sufferings, so that your own present situation may appear to you important and to be envied, and so that it may no longer be your portion to suffer torture in your soul by your longing for more. For he who admires those who have, and whom other men deem blest of fortune, and who spends all his time idly dreaming of them, will be forced to be always contriving some new device because of his [insatiable] desire, until he ends by doing some desperate deed forbidden by the laws. And therefore one ought not to desire other men's blessings, and one ought not to envy those who have more, but rather, comparing his life with that of those who fare worse, and laying to heart their sufferings, deem himself blest of fortune in that he lives and fares so much better than they. Holding fast to this saying you will pass your life in greater tranquillity and will avert not a few of the plagues of life—envy and jealousy and bitterness of mind.

As I grow older I grow calm. If I feel what are perhaps an old man's apprehensions, that competition from new races will cut deeper than working men's disputes and will test whether we can hang together or can fight.
