Go down into your hearts and take the keys of them and ransack your private cupboards, and narrowly observe what junkets your souls have until now lived upon, and gone behind the door and there secretly and stoutly have made a meal of them. Delights are secret things, as treasures are. As dogs … have bones they hide, and secretly steal forth to gnaw upon, so men have sins they hide under their tongues as sweet bits.
