a good heart shines bright and keeps his course truly

William Shakespeare
Henry V
Act 5, Scene 2, Page 6
King Henry V:
"A good leg will fall, a straight back will stoop, a black beard will turn white, a curled pate will grow bald, a fair face will wither, a full eye will wax hollow, but a good heart ... shines bright and never changes, but keeps his course truly. If thou would have such a one, take me."
