Do not think that what is hard for you to master is humanly impossible; but if a thing is humanly possible, consider it to be within your reach.

Take away your opinion, and then there is taken away the complaint, 'I have been harmed.' Take away the complaint, 'I have been harmed,' and the harm is taken away.

Observe and contemplate on the hidden things of life: how a man's seed is but the beginning, it takes others to bring it to fruition. Think how food undergoes such changes to produce health and strength. See the power of these hidden things which, like the wind cannot been seen, but its effects can be.

Give thyself time to learn something new and good, and cease to be whirled around.

Do not act as if you were going to live ten thousand years. Death hangs over you. While you live, while it is in your power, be good.

Were you to live three thousand years, or even thirty thousand, remember that the sole life which a man can lose is that which he is living at the moment; and furthermore, that he can have no other life except the one he loses.

Failure to read what is happening in another's soul is not easily seen as a cause of unhappiness: but those who fail to attend the motions of their own soul are necessarily unhappy.
