As another example, a piece of fabric when taken apart is a pile of yarn; where then is the fabric? Did it disappear? What am I wearing—fabric or yarn? But a strand of yarn is also made up of fibers that are twisted together. So is it fabric, yarn, or fiber that I am wearing? If we again break down the fiber into very fine particles and set this aside, where then is the original fabric? Is it just dust particles that I am wearing? In the sutra system, emptiness is understood by way of this kind of reasoning. It is one method of approaching emptiness, but only as a concept, not an actual experience.
