Egolessness

We have been speaking of Buddha-nature as though it were something that could be described, as though it were similar to the "soul" of other teachings, but it is not.

The concept of an "ego-personality" is something that has been imagined by a discriminating mind which first grasped it and then became attached to it, but which must abandon it. On the contrary, Buddha-nature is something indescribable that must first be discovered. In one sense, it resembles an "ego-personality" but it is not the "ego" in the sense of "I am" or "mine."
