What page is this quote Quiet minds cannot be perplexed or frightened but go on in fortune or misfortune at their own private pace like a clock during a thunderstorm found in the book Dr Jekyll and Mr?

Oh, dude, that quote is from the book "Dr. Jekyll and Mr. Hyde" by Robert Louis Stevenson. It's on page 65. But like, who really needs to know the page number anyway? Just enjoy the quote and let your mind wander, man.
