Imagine that you had gone all your life without ever washing, and then one day you decide to take a shower. You start scrubbing away, but then watch in horror as the dirt begins to ooze out of the pores of your skin and stream down your body. Something must be wrong: You were supposed to be getting cleaner and all you can see is grime. You panic and fling yourself out of the shower, convinced that you should never have begun. But you only end up even more dirty than before. You have no way of knowing that the wisest thing to do is to be patient and to finish the shower. It may look for a while as if you are getting even dirtier, but if you keep on washing, you will emerge fresh and clean. It's all a process, the process of purification.
