Let him set it out on an island; for, when heated, that (cauldron) is suffering pain; and were he to set it out on this (earth) its pain would enter this (earth); and were he to set it out on water, its pain would enter the water; but when he sets it out on an island, then it does not injure either the water or this (earth): in that he does not throw it into the water, it does not injure the water; and in that the water goes all round it--water being a means of soothing--it does not injure this earth;--let him therefore set it out on an island.
