Most people if they really learn to look into their own heart [and that�s what I�m urging you to do right now] most people if they really learn to look into their own hearts would know that they do want and want acutely something that cannot be had in this world. There are all sorts of things in this world that offer to give it to you, but they never keep their promise. The longings which arise in us when we first fall in love or first think of some foreign country or first take up some subject that excites us are longings which no marriage, no travel, no learning can ever really satisfy. I am not speaking of what would ordinarily be called unsuccessful marriages or failures of holidays and so on. I�m speaking of the very best possible ones. There is always something we have grasped at. There�s always something in that first moment of longing but fades away in the reality. The spouse may be a good spouse. The scenery has been excellent. It turned out to be a good job. But it�s evaded us.
