There is means, madam: Our foster-nurse of nature is repose, The which he lacks; that to provoke in him, Are many simples operative, whose power Will close the eye of anguish.
There is a way, madam: Our natural nurse is rest, Which he lacks; to bring it back to him, There are many simple remedies, whose power Will ease his pain.
Doctor · Act 4, Scene 4
The Doctor is with Cordelia, telling her there are ways to heal Lear's shattered mind if she can provide rest and the right medicines. The line matters because it offers the play's first real hope—that healing is possible through gentleness and the body's own capacity to mend. It shows us that nature itself, when tended with care, can undo what cruelty and madness have broken.
