"The idea that just one more dollar, one more dalliance, one more rung on the ladder will leave us feeling sated reflects a misunderstanding about human nature - a misunderstanding, moreover, that is built into human nature; we are designed to feel that the next great goal will bring bliss, and the bliss is designed to evaporate shortly after we get there. Natural selection has a malicious sense of humor; it leads us along with a series of promises and then keeps saying 'Just kidding.'
Remarkably, we go our whole lives without ever really catching on.
The advice of the sages - that we refuse to play this game - is nothing less than an incitement to mutiny, to rebel against our creator.
To cultivate some indifference is one plausible route to liberation. While few of us can claim to have traveled far on this route, the proliferation of this scriptural advice suggests it has been followed some distance with some success."
