Happiness is beneficial for the body, but it is grief that develops the powers of the mind.

Happiness is good for the body, but it is grief which develops the strengths of the mind.

Happiness is salutary for the body but sorrow develops the powers of the spirit.

Why is this painful journey so indispensable to the acquisition of true wisdom?…It is as if the mind were a squeamish organ that refused to entertain difficult truths unless encouraged to do so by difficult events. “Happiness is good for the body,” Proust tells us, “but it is grief which develops the strengths of the mind.” These griefs put us through a form of mental gymnastics which we would have avoided in happier times. Indeed, if a genuine priority is the development of our mental capacities, the implication is that we would be better off being unhappy than content, better off pursuing tormented love affairs than reading Plato or Spinoza. (Proust writes) A woman whom we need and who makes us suffer elicits from us a whole gamut of feelings far more profound and more vital than does a man of genius who interests us.

Because happiness alone is good for the body; whereas sorrow develops the strength of the mind.

Le bonheur est salutaire pour le corps, mais c'est le chagrin qui développe les forces de l'esprit.

It is grief that develops the powers of the mind.

السعادة مفيدة للجسد، لكن الأسى هو ما ينمي قدرات العقل.

Happiness is so nonsynonymous with joy or pleasure that it is not infrequently sought and felt in grief and deprivation.

It is not good to feel too much joy, nor to be glad that our body lives. For we matter not and it must not matter to us whether we live or die, which is to be as our brothers will it. But we, Equality 7-2521, are glad to be living. If this is a vice, then we wish no virtue.

The question of desirable grief and pain or the necessity for it must also be faced. [Are] growth and self-fulfillment possible at all without pain and grief and sorrow and turmoil? If grief and pain are sometimes necessary for growth of the person, then we must learn not to protect people from them automatically as if they were always bad.

Not allowing people to go through their pain, and protecting them from it, may turn out to be a kind of overprotection, which in turn implies a certain lack of respect for the integrity and the intrinsic nature and the future development of the individual.

As difficult as it is to endure, depression has elements that can be helpful in grief. It slows us down and allows us to take real stock of the loss. It makes us rebuild ourselves from the ground up. It clears the deck for growth. It takes us to a deeper place in our soul that we would not normally explore.

Happiness is the indication that man has found the answer to the problem of human existence: the productive realization of his potentialities and thus, simultaneously, being one with the world and preserving the integrity of his self. In spending his energy productively he increases his powers, he "burns without being consumed.“

[Happiness is] The exercise of vital powers, along lines of excellence, in a life affording them scope.
