.Анна Каренина

“You must understand,” said he, “it’s not love.  I’ve been in love, but it’s not that.  It’s not my feeling, but a sort of force outside me has taken possession of me.  I went away, you see, because I made up my mind that it could never be, you understand, as a happiness that does not come on earth; but I’ve struggled with myself, I see there’s no living without it.  And it must be settled.”

-Levin from Анна Каренина, Lyev Nikolayevich Tolstoy
