" Anything that is alive will die one day and its body will return to the earth... Which in turn makes the flowers and grass grow.

In the same way, our souls become nourishment for the people around us, and live on through the memories of those we loved.

Everything in this world has a flow. Even human lives. "

― Hiromu Arakawa , Fullmetal Alchemist, Vol. 5 (Fullmetal Alchemist, #5)
