• Katuviya Sutta

Once when the Buddha was going about for alms near the fig-tree at the cattle tethering in the neighbourhood of Isipatana, he saw a monk, whose delight was in the empty outer joys of sense, and admonished him, saying that flies will settle on and attack him who is corrupt and reeks with the stench of carrion. Hearing this, the monk was greatly stirred. Later the Buddha repeated the admonition to the assembled monks and explained that greed was corruption, malice the stench of carrion and evil ways of thought the flies. A.i.280f.
