This is one of the final works of Jung, and is absolutely monstrous in its size and depth. Unless your familiar with most of his later writings, particularly the ones relating to Alchemy, then I wouldnt even begin to consider reading this book. Those who have read a few of his works, and know his general theory... will still find this hard going, but extremely rewarding. This should be one of the last books you read by Jung, and by the end of that journey you will be grateful that you began it. Jung is not only for those specifying in psychology. The legacy of this man, to psychology/philosophy/spiritualism & life is awesome & almost unrivaled.
