When you kill a beast say to him in your heart: “By the same power that slays you, I too am slain; and I too shall be consumed. For the law that delivered you into my hand shall deliver me into a mightier hand. Your blood and my blood is naught but the sap that feeds the tree of heaven.”
(當你宰殺一隻野獸時，當在心中對牠說：「奪走你生命的力量同樣也會來奪走我；我也同屬於那會被吞食的。今日把你送到我手上的法則將來也會把我交付給更高的權柄。而你我的鮮血也不過只是用來餵養天堂木的汁液。」)

— Kahlil Gibran (1883～1931)
