You want what you think you know, and this is what constitutes the basis of your understanding of yourself and your world. In fact, this constitutes the basis of your whole identity. You will find, however, upon honest examination that your understanding is based upon assumptions primarily, and these assumptions have not been founded upon your experience to a very great degree, if at all.
Today in your three brief practice periods, in which you devote your total attention to examining your assumptions, think about the things you really think you know, including things that you have not thought to question before—things that you think you know. Today’s exercise, then, carries forth from the previous steps where you begin to see the difference between what you think you know and real Knowledge itself and the relationship between what you think of as Knowledge and your own assumptions, beliefs and hopes for things.
Therefore, in each practice session it is very essential for you to think about the things you think you know. When you realize they are based primarily upon your assumptions, you will realize how weak is your foundation in the world. Understanding this may be upsetting and disconcerting, but it is absolutely essential for you to give you the impetus and the desire to discover your true foundation in the world.
