To crush, to annihilate a man utterly, to inflict on him the most terrible of punishments so that the most ferocious murderer would shudder at it and dread it beforehand, one need only give him work of an absolutely, completely useless and irrational character.

Love is a teacher, but one must know how to acquire it, for it is difficult to acquire, it is dearly bought, by long work over a long time, for one ought to love not for a chance moment but for all time. Anyone, even a wicked man, can love by chance.

It's in the homes of spiteful old widows that one finds such cleanliness.

Above all, avoid lies, all lies, especially the lie to yourself. Keep watch on your own lie and examine it every hour, every minute. And avoid contempt, both of others and of yourself: what seems bad to you in yourself is purified by the very fact that you have noticed it in yourself. And avoid fear, though fear is simply the consequence of every lie. Never be frightened at your own faintheartedness in attaining love, and meanwhile do not even be very frightened by your own bad acts.

Woe to the suicides! I believe that there can be none more miserable than they. Oh, there are some who remain proud and fierce even in hell, in spite of their certain knowledge and contemplation of the absolute truth; there are some fearful ones who have given themselves over to Satan and his proud spirit entirely. For such, hell is voluntary and ever consuming; they are tortured by their own choice. For they have cursed themselves, cursing God and life. And they will burn in the fire of their own wrath forever and yearn for death and annihilation. But they will not attain to death.

There is only one thing that I dread: not to be worthy of my sufferings.
