Makkata Sutta

In certain tracts of the Himālaya where monkeys resort, hunters set up traps of pitch to catch the monkeys. Wise monkeys avoid the traps, but the foolish ones handle the pitch and their paws stick in it, one after another, and finally their muzzles, in their struggles to escape. So it is with foolish men who allow their senses to roam in wrong pastures -  the objects of the senses. S.v.148.
