"your arms will grow weak, your legs will lose their swiftness. a youth will be able to take the knife from your hand. how will skill or ferocity avail you then? heart and mind are the true weapons. but did you learn to use the spear in a day? if you do not hone mind and heart now, you will grow old and children will befuddle your wits. when you speak, all will hear only the wind. take heed while you can."

- tamela, in robert jordan's "winter's heart"
