Death is obviously made visible in those people have known and are no longer with us: erstwhile companions of the daylight who are now in the sunless realm. The dead occupy that outside-of-life, of the sum total that we designate by the term 'the human world', to which we can refer so easily that we do not notice, or admit, that it is too difficult to imagine. Thinking of the deaths of those others is a way of approaching the least imaginable of all deaths, our own, and of trying to conceive the inconceivable the cessation of our own existence, of we who are at this moment trying to conceive this event. The idea of death is a threat, a goad and an inspiration. And its power is available to all of us who aim to live abundantly. In death's dark mirror, the light of daylight seems luminous, inexplicable and precious.
