If a man were to catch six animals - a
snake, a crocodile, a bird, a dog, a jackal and a monkey - and tether them with
ropes, they would struggle to be free and to make off, each to his own range or
pasture. So do a man's six senses. If the animals are strongly tethered, they
will, with time, grow weary and rest. So will the six senses if one practises
attention to the body. S. iv.197; cp. Vsm.484.
