" In various traditions the witness has been identified with “Real I,” “the true self,” and “essential being,” but all of this naming misses the point. Witnessing is, if anything, a verb: an innate capacity of human consciousness to be present to itself as a field of awareness. Though personal, it is not a person—not an other—but a subtle capacity of consciousness itself, so far as we know gifted to the human species alone. Its purpose seems to be to keep track simultaneously of the horizontal axis—our life in time—and the pure divine awareness that is always intersecting this axis. "
