3.242

佛本行經云。世尊與難陀比丘至魚肆。佛令難陀取少籍魚草。握少時棄之。令臭手問之。難陀曰。唯有腥臭之氣。又至香店令取裹香紙。掬少時棄之。復問難陀。答唯聞香氣。佛語難陀。善友惡友相染習亦復如是。若親善友。必定當得廣大名聞。

The Scripture of the Buddha's Former Deeds says: 'The World-Honoured One and the monk Nanda went to a fish market. The Buddha told Nanda to take a small piece of thatch used for fish, hold it for a short while, and then throw it away. He had him smell his hand and asked him about it. Nanda said: "There is only a foul, fishy odour." Then they went to an incense shop, and he had him take a piece of paper that had wrapped incense, hold it for a short while, and then throw it away. He asked Nanda again, who replied: "I only smell fragrance." The Buddha said to Nanda: "The contagion of habit from good friends and bad friends is just like this. If one associates closely with good friends, one will definitely attain wide renown."'
