Death must be so beautiful. To lie in the soft brown earth, with the grasses waving above one's head, and listen to silence. To have no yesterday, and no tomorrow. To forget time, to forgive life, to be at peace.

This quote is saying that death must be peaceful and beautiful. It is a place of rest, where there is no worry about the past or future. There is no noise, only the peaceful sound of silence. The speaker is imagining being surrounded in the soft earth and the waving grasses in the sky. They are envisioning a place of no yesterday and no tomorrow, where one can forget about the troubles of life and find peace.
