In realizing that you are able to set aside, mentally, these sensations--that you are able to hold them out at arm's length and "consider" them as an "outside" thing, you mentally determine that they are "not I" things, and you set them down in the "not I" collection--the first to be placed there. Let us try to make this still plainer, even at the risk of wearying you by repetitions (for you must get this idea firmly fixed in your mind). To be able to say that a thing is "not I," you must realize that there are two things in question (1) the "not I" thing, and (2) the "I" who is regarding the "not I" thing just as the "I" regards a lump of sugar, or a mountain. Do you see what we mean? Keep at it until you do. Next, consider some of the emotions, such as anger; hate; love, in its ordinary forms; jealousy; ambition; and the hundred and one other emotions that sweep through our brains. You will find that you are able to set each one of these emotions or feelings aside and study it; dissect it; analyze it; consider it. You will be able to understand the rise, progress and end of each of these feelings, as they have come to you, and as you recall them in your memory or imagination, just as readily as you would were you observing their occurrence in the mind of a friend. You will find them all stored away in some parts of your mental make-up, and 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.
