To understand the true quality of people, you must look into their minds, and examine their pursuits and aversions.

Never value anything as profitable to thyself which shall compel thee to break thy promise, to lose thy self-respect, to hate any man, to suspect, to curse, to act the hypocrite, to desire anything which needs walls and curtains.

The happiness of your life depends upon the quality of your thoughts.

Remember that the sole life which a man can lose is that which he is living at the moment.

Think of all the years passed by in which you said to yourself "I'll do it tomorrow," and how the gods have again and again granted you periods of grace of which you have not availed yourself. It is time to realize that you are a member of the Universe, that you are born of Nature itself, and to know that a limit has been set to your time. Use every moment wisely, to perceive your inner refulgence, or 'twill be gone and nevermore within your reach.

Look back over the past, with its changing empires that rose and fell, and you can foresee the future, too.

Humans have come into being for the sake of each other, so either teach them, or learn to bear them.
