I always feel that we humans have a tendency to escape, laze and remain detached. It comes so naturally to us. But this centrifugal force is so destructive: if you indulge in this state of mind you don't exist!
Now what is the counter force? Nature has provided us with a tool which keeps you illusioned and smiling. You continue to believe that it is all real. And that tool is Desire. You taste it once in any form and you ask for more. It keeps you hooked to this thing called life. And the strongest of all the desires is sex!
