Upon a Quiet Conscience

Close thine eyes and sleep secure,Thy soul is safe, thy body sure;He that guards thee, he that keeps,Never slumbers, never sleeps.A quiet conscience, in a quiet breast,Has only peace, has only rest:The music and the mirth of kingsAre out of tune, unless she sings.Then close thine eyes in peace, and rest secure,No sleep so sweet as thine, no rest so sure.
