The self that does not survive scrutiny is the of experience in each present moment—the feeling of being a thinker of thoughts one's head, the sense of being an owner or inhabitant of a physical body, which this false self seems to appropriate as a kind of vehicle. Even if you don't believe such a homunculus exists—perhaps because you believe, on the basis of science, that you are identical to your body and brain rather than a ghostly resident therein—you almost certainly like an internal self in almost every waking moment. And yet, however one looks for it, this self is nowhere to be found. It cannot be seen amid the particulars of experience, and it cannot be seen when experience itself is viewed as a totality. However, its can be found—and when it is, the feeling of being a self disappears.
