the pains and the miseries

All this that you see, the pains and the miseries, are but the necessary conditions of this world. Poverty and wealth and happiness are but momentary. They do not belong to our real nature at all. Our nature is far beyond misery and happiness, beyond every object of the senses, beyond the imagination. And yet we must go on working all the time.
