Pi Gu is a fasting program which comes from traditional Taoist practices. This is a lost art in China and with this book Tom has not only introduced this system to the Western world but provided those cultures previously familiar with the teachings a record of its existence and usage. The Pi Gu system is used by Tom in his clinic for weightloss and also for those looking to increase their spiritual understandings. This text explains the theory behind Pi Gu and also provides a discussion and explanation of the Tai Chi Dao Yin system of Qi Gong. Dao Yin is a simple exercise routine that is helpful for those in the Pi Gu fasting state as well as for building and maintaining health.
