Master Sun was famous for his writings and healing, and was very knowledgeable about Lao-Zhuang (Chinese philosophical teachings), and herbal medicine. He emphasized preventive measures against diseases and focused on food therapy, supplemented with purging one’s mind of desires and ambitions. This is further supported by methods of ingesting vital breath, namely, embryonic breath, introspection, breath-holding and hissing breath, to stay healthy. Master Sun has been canonized as God of Chinese Medicine. ]]>
