So it is with us, the children of the world. Our likes and infatuations have a certain limit; when their time has expired the period of indifference commences. When the water of indifference is drunk, then there is no more wish for anything in the world. The nature of the water one drinks in this world is that one's thirst is quenched for a certain time, and then comes again. When the water of divine knowledge is drunk, then thirst never comes again.
