Andrew said: Book for emotional/spiritual aspect of five element theory: Lorie Eve Dechar, The Five Spirits. This book is not TCM, it is from Worsley style medicine derived from pre-TCM classical Chinese theory. If you want something that is straight TCM, try the Giovanni Maciocia text (newer version is 2015?- worth the extra $$) listed in the references on the slides. Look up "emotions" in the index and you will find more detailed explanations.
