Way of the Celestial Masters

The Way of the Celestial Masters (Tiānshī Dào 天師道) was a Daoist movement founded in 142 AD. The founding of this movement is commonly attributed to Zhang Ling 張陵, a hermit who lived during the Later Han, but it is possible that was a separate group until its forcible take-over by Zhang Ling's grandson Zhang Lu 張魯. In any case, Zhang Ling passed on his teachings to Zhang Heng, and Zhang Ling, Zhang Heng and Zhang Lu.
