26.131

又勅捨云。僧辯所道自死肉。若如此說。鴟鴉鳩鴿觸處不死。那不見有一自死者。麞鹿雉兔充滿野澤。亦不甞見有一自死者。而覓死肉其就屠殺家。覓死魚必就罾網處。若非殺生豈有死肉。經言。買肉與自殺。此罪一等。我本不自為。正為諸僧尼作離苦因緣。

The edict further addressed Zhou She, saying: "Regarding what Sengbian said about meat from animals that died of themselves: if spoken of like this, kites, crows, doves, and pigeons die in every place—why does one never see a single one that died of itself? Roes, deer, pheasants, and hares fill the wilds and marshes, yet one has never seen a single one that died of itself either. But when seeking meat of the dead, one always goes to a butcher's house; when seeking dead fish, one must go to the place of fishing nets. Were it not for killing living beings, how could there be meat of the dead? The sūtra says: 'Buying meat and killing it oneself—these sins are equal.' Originally, I did not do this for myself, but precisely to create for the monks and nuns the causes and conditions for leaving suffering."
