I have read about a colonel who retired from military life. He called his orderly, whose name was Rama, and told him that he was to live with him. The colonel lived on his own, he had no wife or children, so he told Rama, "Your only duty will be to wake me up at four a.m. just as you have been doing all these years. For years you have come to me at four in the morning with the words, 'Wake up, sir, it's time for the parade.' All I want you to do from now on is to come to me at four in the morning and say, 'Wake up, sir, it's time for the parade.' And then I'll say to you, 'The parade can go to hell,' and I'll turn over and go back to sleep! This has been my lifelong desire which I have not been able to fulfill up to now. My whole life I wanted to skip the parade but could not do so. Now I am retired, so...." 
Such is our mind. It wants to sleep, and when it is time to wake up, then we get even more pleasure from going on sleeping if we are given the chance. Now this colonel is insane, but he represents man truly. Now he can go on sleeping uninterrupted, there is no need to keep the orderly any more for waking him up at four in the morning. But the real interest is in someone making the effort to wake him up and his turning over and going on sleeping and ignoring him. This satisfaction is not possible even in the natural uninterrupted sleep.
