The aim of this book is to provide ‘The Golden Key’ to help unlock the hidden treasures within each of us as individuals. We will be reconnecting with the lost wisdom and knowledge of humanity, our heritage which stretches over the last five millennia. Understanding our own unique, individual temperament will facilitate us to tune into the vast treasures of knowledge within the healthcare traditions of Africa, China, India, Europe and Arabia. This reconnection with sacred knowledge, together with the accumulated experience of humanity, brings us towards wholeness and balance. Understanding temperament helps us to make sense of all of the available information and data, which is meaningless without this framework. This helps us to achieve higher health, wellbeing and enlightenment.
