Life seems to me to be the ongoing resolution of fear of dying. Either we feel carefree peace of "Heaven," or unconsciously strive for it through attempting to settle our anxieties. When a person approaches death, often he experiences a calming, or otherwise attempts to reconcile his life "flashing before (his) eyes." Those who feel unsettled toward death I surmise would be less inclined to die; those who feel Nirvana would be more inclined to meet it. Some people live a life blessed with peace, others have walked through an earthly Hell through no fault of their own. Whether or not one survives in this world to avoid death, or seeks peace in a Heaven on Earth, we are reconciling toward an unknown day and in an unknown place our certain death.
