Death was thus to become the lot of our forefathers, just as it lies in store for us who are now living, and our body was rendered mortal. Death is thus a kind of protracted process or, rather, there are myriads of deaths, one death succeeding the next until we reach the one final and long-enduring death. For we are born into corruption, and having once come into existence we are in a state of transiency until we cease from this constant passing away and coming to be. We are never truly the same, although we may appear to be so to those who do not observe us closely. Just as a flame that catches one end of a slender reed changes continually, and its existence is measured by the length of the reed, so we likewise are ever changing, and our measure is the length of life appointed to each of us.
~St Gregory Palamas (Philokalia vol.4, p.371)
