You relax within the verse. You realize the structure of the verse and relax into it. It's like swimming. Or riding a bike. You can't make it sound real if you are thinking it through as you go. You can't think through Shakespeare, you have to speak it. And listen to the rhythm of it and then it takes you over. And to make it sound real you speak as if you believe it. Don't act it. Just be it.
Anthony Hopkins
