Word for a short sentence packed with information

I was wondering what the correct word would be for a sentence that is tightly packed with meaning. For example, a good aphorism. An aphorism is short, but has a lot of meaning behind it and requires considerable thought in order to understand it.

I thought of the word dense (as in "this is a very dense passage that takes some time to understand"). But in my mind, dense implies that its more technical and difficult to read. I'm trying to describe a simple passage that has a lot of meaning behind it. For example, a passage like this:

We can forgive a man for making a useful thing as long as he does not admire it. The only excuse for making a useless thing is that one admires it intensely. (The Picture of Dorian Gray, Oscar Wilde)

Edit: Just for more context. I sent the preface of The Picture of Dorian Grey to a friend, he quickly read it and said that he didn't understand it, and I said "you have to think about it, that page is really dense." I need a word to replace dense in that context.
