Suppose that you have observed yourself for some considerable time and you begin to see yourself over the period of time acting in a certain way. You see how something starts, leads to something else, and so on. In fact, you see yourself in action, in movement, so to speak, inner and outer, in some typical way of behavior. This is a photograph.

But this Work tells you to observe yourself in the light of what the Work teaches, so that you can change yourself. That is, it starts inside you, like a spy, inside your heavily guarded fortifications. Yes, Observing 'I' is a spy.
