John Muir said this quote

On no subject are our ideas more warped and pitiable than on death. ... Let children walk with nature, let them see the beautiful blendings and communions of death and life, their joyous inseparable unity, as taught in woods and meadows, plains and mountains and streams of our blessed star, and they will learn that death is stingless indeed, and as beautiful as life, and that the grave has no victory, for it never fights.

~ John Muir

This time it is real — all must die, and where could mountaineer find a more glorious death!

~ John Muir

Yet how hard most people work for mere dust and ashes and care, taking no thought of growing in knowledge and grace, never having time to get in sight of their own ignorance.

~ John Muir

Another glorious Sierra day in which one seems to be dissolved and absorbed and sent pulsing onward we know not where. Life seems neither long nor short, and we take no more heed to save time or make haste than do the trees and stars. This is true freedom, a good practical sort of immortality.

~ John Muir
