In Daoism, the clear Yang qi manifests in physical and mental vitality, robust health, vibrant voice, bright mind, love, kindness, ease, purity and clarity.
The dark and turbid Yin qi manifests in various physical and mental diseases, greed, lust and salacity, anger, jealousy, arrogance and hatred.
The concept of transforming turbid Yin and cultivating clear Yang is well known in Daoist cultivation. Kindness is the key to restore the Yang qi. The kind mind and actions accumulate positive Yang energy in the body 善能升阳. And while the Yang qi increases, the turbid Yin qi slowly declines and disappears. As the Chinese medicine saying goes,"when the sun shines, the Yin haze scatters by itself" 阳光普照，阴霾自散.
