What an interessting question. I have always found the sentence the other way around: what death tells life (especially in pathological institutes). What ist the subject of the study?
Thanks for your interest in the question. unwanted and agonizing impulses are suppressed deep in our unconscious far from the reach of awareness in order to make our life less miserable.Same is the case with the thoughts and feeling about death.Good part of our life is spend to detach our-self from thinking and reflection about death and especially avoiding to think about the very experience of dying. What type of inner dialogue or self talk we practice in order to avoid this ultimate reality. What type of mental dialogue is going on deep inside us with the approaching ending that keep us alive even when the writing is very much on the wall .
