What is Our Highest Purpose?

Allow me to draw your attention to an apparently surprising thing. If I told you that now, when you are reading these lines, you are in fact asleep, you would certainly believe that I have gone mad.

Your are awake, you are concentrating your attention to reading, and you are aware of your environment as well. You can see the furniture of your room, you can hear the call of the birds from the nearby forest. You are also aware of your thoughts and emotions, too. How can anyone claim that you are asleep in this very moment?

Naturally, you, just as everyone else, sleep at night, and yes, sometimes you see dreams while you sleep.  But now it is daytime, you are awake, so how could you see dreams?
