Plato and the Greeks called it ''daimon'', the Romans ''genius'', the Christians ''Guardian Angel'' - and today we use terms such as ''heart'', ''spirit'' and ''soul''. For James Hillman it is the central and guiding force of his utterly unique and compelling ''acorn theory'' which proposes that each life is formed by a particular image, an image that is the essence of that life and calls it to a destiny, just as the mighty oak''s destiny is written in the tiny acorn.Highly accessible and imaginative, The Soul''s Code offers a liberating vision of childhood troubles and an exciting approach to themes such as freedom, and, most of all, calling - that invisible mystery at the centre of every life that voices the fundamental question, ''What is in my heart that I must do, be and have? And why?''
