Quote I don't quite get

[Zoom]

Came across this earlier. I sense there is something great and important in this, but I can't quite grasp it. What do you guys think?

"The mold in which a key is made would be a strange thing, if you had never seen a key: and the key itself a strange thing if you had never seen a lock. Your soul has a curious shape because it is a hollow made to fit a particular swelling in the infinite contours of the divine substance, or a key to unlock one of the doors in the house with many mansions.

Your place in heaven will seem to be made for you and you alone, because you were made for it -- made for it stitch by stitch as a glove is made for a hand."

C. S. Lewis, The Problem of Pain

That's sorta strange. I totally get what this is. He is saying that Heaven will be perfect because you were made for that happiness. Everything about you will be fulfilled

Oh, that's seriously all it is?
I was thinking more along the lines of "what you define as happiness is happiness to you because you are the product of your experiences and so are your values" or some such thing.
