The nature of the mind is to acquire, to absorb, is it not? Or rather, the pattern it has created for itself is one of gathering in; and in that very activity the mind is preparing its own weariness, boredom. Interest, curiosity, is the beginning of acquisition, which soon becomes boredom; and the urge to be free from boredom is another form of possession. So the mind goes from boredom to interest to boredom again, till it is utterly weary; and these successive waves of interest and weariness are regarded as existence.
