“In a word, there is nothing closer to you than you.  If you do not know yourself, how can you know anything else?  ....  you must seek out the truth about yourself: What sort of a thing are you?  Where did you come from?  Where are you going?  Why have you come to this stopping place?  For what purpose were you created?  What is your happiness and in what does it lie?  What is your misery and in what does that lie?”
