Q. Do you mean we should practice observing these different functions?\n\n A. Yes, at certain moments of the day we must try to see in ourselves what we think, how we feel, how we move and so on. At one time you can concentrate on the intellectual function, at another time on the emotional, then on the instinctive or the moving. For instance, try to find out what you are thinking about, why you think and how you think about it. Try to observe physical sensations such as warmth, cold, what you see, what you hear. Then, every time you make a movement you can see how you move, how you sit, how you stand, how you walk and so on. It is not easy to separate instinctive functions, because in ordinary psychology they are mixed with the emotional; it takes some time to put them in their right place.
