A man shall not be full of laughter and mockery, nor sad and mournful, but joyful. ... His desire shall not be so great that he rushes for wealth, nor shall he be lazy and refrain from working. But he shall live in contentment, have a modest occupation, and be occupied mainly with the Torah.

Unhappy is the fate of one who tries to win his battles and succeed in his attacks without cultivating the spirit of enterprise; for the result is waste of time and general stagnation.

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.

We find our population suffering from old inequalities, little changed by vast sporadic remedies. In spite of our efforts and in spite of our talk, we have not weeded out the over privileged and we have not effectively lifted up the underprivileged. Both of these manifestations of injustice have retarded happiness. No wise man has any intention of destroying what is known as the profit motive; because by the profit motive we mean the right by work to earn a decent livelihood for ourselves and for our families. We have, however, a clear mandate from the people, that Americans must forswear that conception of the acquisition of wealth which, through excessive profits, creates undue private power over private affairs and, to our misfortune, over public affairs as well. In building toward this end we do not destroy ambition, nor do we seek to divide our wealth into equal shares on stated occasions. We continue to recognize the greater ability of some to earn more than others. But we do assert that the ambition of the individual to obtain for him and his a proper security, a reasonable leisure, and a decent living throughout life, is an ambition to be preferred to the appetite for great wealth and great power.

O SON OF MAN! Should prosperity befall thee, rejoice not, and should abasement come upon thee, grieve not, for both shall pass away and be no more.

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.

The sages taught the Jews not to rejoice over another’s misfortune. “Rejoice not when thine enemy falleth” (Proverbs 24:17). (I must confess that I have always enjoyed gloating over the comeuppance suffered by the detestable, regardless of race, color, or creed.)

How could a decent person ever rejoice in victory and delight in the slaughter of men

The Upanishads point out that the goal of man is neither misery nor happiness, but we have to be master of that out of which these are manufactured. We must be masters of the situation at its very root, as it were.

Even as he who glories while he gains will, when the time has come to tally loss, lament with every thought and turn despondent,
