摩訶止觀 7.94

7.94

一旦命終，假借還本：風去火冷，地壞水流；蟲噉鳥啄，頭手分離，盈流於外；三五里間逆風聞臭，惡氣腥臊衝人鼻息；惡色黮瘀污人眼目，劇於死狗。是名「究竟不淨」。

Once life comes to an end, the borrowed [elements] return to their origins: wind departs and fire cools, earth disintegrates and water flows away. Eaten by worms and pecked by birds, head and hands separated, overflowing outwards; for three to five leagues downwind its stench is smelled, the foul and rank odor assailing people's breath; its ghastly, bruised discoloration offends people's eyes, worse than a dead dog. This is called 'ultimate impurity.'
