How does an enlightened mind distinguish itself from all other phenomena? There is one such person amidst a crowd of other people. Somebody shouts their name, and they say, "yes, that is I. I am here. What do you want?" After hearing his name, how does he make the connection between the hearing of his name and referencing that name to himself, so that he then responds thus, "yes, that is I. I am here. What do you want?"
