[183] "Householder's son, there are these six dangers (ādīnava) in habitually associating with bad friends: those who are rogues, those who are debauchees, those who are drunkards, those who are cheats, those who are swindlers, and those who are violent — these become his friends, these his companions. These, householder's son, are the six dangers in habitually associating with bad friends."
