The Prose Edda 2.70

The heart is called grain-sheaf; [one should periphrase it by terming it Grain or Stone or Apple or Nut or Ball, or the like, in figures of the breast or of feeling. More over, it may be called House or Earth or Mount of Feeling. One should periphrase the breast by calling it House or Garth or Ship of the Heart, of Breath, or of the Liver; Land of Energy, of Feeling, and of Memory]. Feeling is affection and emotion, love, passion, desire, love-longing. [Passion should be periphrased by calling it Wind of Troll Women; also it is correct to name what one soever is desired, and to name giants, periphrasing giantesses as Woman or Mother or Daughter of the Giants.] Feeling is also called mood, liking, eagerness, courage, activity, memory, understanding, temper, humor, good faith. It is also wrath, enmity, mischievousness, grimness, balefulness, grief, sorrow, ill-will, spite, falseness, faithlessness, fickleness, light-mindedness, baseness, hasty temper, violence.
