If we lack the proper antidotes of emptiness and bodhichitta, we will not be able to control our minds when frightening appearances manifest. It is considered a sign of progress in this practice if we go unconscious, and then, when we wake up, have forgotten our names and whose bodies we have! This is the ceasing of clinging to the body.
