you may (to use a modern American slang phrase) "make them trot before
you, and show their paces." Don't you see that they are not "You"--that
they are merely something that you carry around with you in a mental bag.
You can imagine yourself as living without them, and still being "I," can
you not?

And the very fact that you are able to set them aside and examine and
consider them is a proof that they are "not I" things--for there are two
things in the matter (1) _You_ who are examining and considering them,
and (2) the thing itself which is the _object_ of the examination and
consideration at mental arm's length. So into the "not I" collection go
these emotions, desirable and undesirable. The collection is steadily
growing, and will attain quite formidable proportions after a while.

Now, do not imagine that this is a lesson designed to teach you how to
discard these emotions, although if it enables you to get rid of the
undesirable ones, so much the better. This is not our object, for we bid
you place the desirable (at this time) ones in with the opposite kind,
the idea being to bring you to a realization that the "I" is higher,
above and independent of these mental somethings, and then when you have
realized the nature of the "I," you may return and use (as a Master) the
things that have been using you as a slave. So do not be afraid to throw
these emotions (good and bad) into the "not I" collection. You may go
back to them, and use the good ones, after the Mental Drill is over. No
matter how much you may think that you are bound by any of these
emotions, you will realize, by careful analysis, that it is of the "not
I" kind, for the "I" existed before the emotion came into active play,
and it will live long after the emotion has faded away. The principal
proof is that you are able to hold it out at arm's length and examine
it--a proof that it is "not I."
