A reflective, contented mind is the best possession.

A contented mind is the greatest blessing a man can enjoy in this world.

Upon the whole, a contented mind is the greatest blessing a man can enjoy in this world.

The noble-minded have nine states of mind: for eyes, bright; for ears, penetrating; for countenance; cordial; for demeanor, humble; for words, trustworthy; for service, reverent; for doubt, questioning; for anger circumspect; and for facing a chance to profit, moral.

Sweet are the thoughts that savour of content;
The quiet mind is richer than a crown.

The truest greatness lies in being kind, the truest wisdom in a happy mind.

Although all the qualities of mind may be united in a great genius, yet there are some which are special and peculiar to him; his views are unlimited; he always acts uniformly and with the same activity; he sees distant objects as if present; he comprehends and grasps the greatest, sees and notices the smallest matters; his thoughts are elevated, broad, just and intelligible. Nothing escapes his observation, and he often finds truth in spite of the obscurity that hides her from others. A lofty mind always thinks nobly, it easily creates vivid, agreeable, and natural fancies, places them in their best light, clothes them with all appropriate adornments, studies others' tastes, and clears away from its own thoughts all that is useless and disagreeable.

Sweet are the thoughts that savour of content, The quiet mind is richer than a crown...

By a tranquil mind I mean nothing else than a mind well ordered.

Extraordinary minds understand that happiness comes from within.

To all this, his illustrious mind reflects the noblest ornament; he places no part of his happiness in ostentation, but refers the whole of it to conscience; and seeks the reward of a virtuous action, not in the applauses of the world, but in the action itself.

Life in accordance with intellect is best and pleasantest, since this, more than anything else, constitutes humanity.

Happiness is at once the best, the noblest, and the pleasantest of things.

The cultivation of the intellect is man's highest good and purest happiness
