Dillard states that once one accepts the inevitability of death, the rest is easy. What might she mean by that?

She seems to be implying that in accepting death, one is then able to accept whatever is the means that leads to death. These two ideas, one that everything dies, and two, that accepting this fact makes living easy, seem simplistic and perhaps idealistic. However, one needs only to observe how most humans struggle against their own death when faced with a mortal illness to understand that perhaps the "rest is [not] easy."
