Stand guard at the portal of your mind.

The soul is not born; it does not die; it was not produced from anyone… Unborn, eternal, it is not slain, though the body is slain.

Man is the broken giant, and in all his weakness both his body and his mind are invigorated by habits of conversation with nature.

Can anything be so elegant as to have few wants, and to serve them one's self?

People forget that it is the eye which makes the horizon, and the rounding mind's eye which makes this or that man a type or representative of humanity with the name of hero or saint.

All life is an experiment. The more experiments you make the better.

The action of the soul is oftener in that which is felt and left unsaid than in that which is said in any conversation. It broods over every society, and men unconsciously seek for it in each other.
