C.S. Lewis on Heaven

Small excerpt from The Problem of Pain by my beloved C.S. Lewis:

"You may have noticed that the books you really love are all bound together by a secret thread. You know very well what is the common quality that makes you love them, though you cannot out it into words: but most of your friends do not see it at all [...] Again, you have stood before some landscape, which seems to embody what you have been looking for all your life; and then turned to the friend at your side who appears to be seeing what you saw-- but [...] you realise that this landscape means something totally different to him [...] Are not all lifelong friendships born at the moment when at last you meet another human being who has some inkling (but faint and uncertain even in the best) of that something which you were born desiring, and which, beneath the flux of other desires and in all the momentary silences between the louder passions, night and day, year by year, from childhood to old age, you are looking for, watching for, listening for?"
