Don't worry about death became his most fundamental, most liberating answer to the question of how to live. It made it possible to do just that. Live.

In the book
He insisted that if you do not know how to die you need not worry, because nature will tell you what to do on the spot, fully and adequately, and will do the job perfectly without your fussing. In time "don't worry about death" became his most liberating answer to the whole question of how to live — the answer that finally made it possible to do just that: live. His acceptance was never half-hearted; it was a full and generous yes to death, and through it, to life. — The Landing (Death)
