SARAH: Because of his evil deeds, Claudius has become cold-hearted. Not only have his heartstrings, the tendons around his heart, become as hard as steel, but so have the tendons in his knees, which are too proud to bow down in prayer. He wants both sets of tendons to be as soft as those of a baby — those around his heart so he can feel remorse, which would allow him to repent, and those in his knees, so he can kneel in prayer.

RALPH: It's just at this point that Hamlet enters unobserved, spotting Claudius kneeling in prayer.
