The foundations of Yin yoga are rooted in the Daoist traditions of ancient China. Daoism is a multifaceted system premised upon the philosophy of living in harmony with the Dao, with the way of nature. Yin yoga is a synthesis Paulie Zink created by combining Hatha yoga and several disciplines from the Daoist tradition along with insights, visualisations, and animal based yoga postures, movements, and vocalisations he developed himself. The Daoist components of Yin yoga involve Dao Yin (yoga postures), Qigong, inner alchemy, philosophy, and mysticism.
