Your mind is engrossed in the objects created by Illusion (Maya). This includes even the body. As long as your mind is involved in Maya you have the concepts of "you" and "I." The whole struggle in Illusion is because you want the body only to get what the mind considers to be "good." Because you devote your mind to this struggle, the world exists. Because there are students, there are teachers. If the students go away, for whom is the teacher? Because there is objective knowledge, "you" exist.
