The term ego—or ego-self—is frequently used to describe the self-centered, fabricated outer layer of self, and we often speak of letting go of the ego, or dissolving it, or transcending it. I myself had thought of adding wood to the fire as an ego-suicide mission. However, the common usage of ego, both within Buddhist teachings and in the world at large, makes ego sound like an entity that has a shape and a size, and that can be extracted like a tooth. It doesn't work that way.
