The Chongxuan School (Chinese: 重玄, pinyin: Chóngxuán) was a Taoist philosophical current influenced by Buddhist Madhyamaka thought.
[6] The Xuanxue thinkers deduced from this phrase the infinite depth, hence the transcendence of the Dao, and its empty nature (wú 無).
In practice, Jizang's "forgetfulness in two steps" (jiānwàng 兼忘) will be accomplished; this inspired the Shangqing patriarch Sima Chengzhen's seven-step instructions of the Zuowanglun.
On the other hand, Chongxuan thinkers also relied on the Zhuangzi, many of whose passages center around the overcoming of conceptual oppositions.
[10] Active at a time when the Tang state had great influence over and gave patronage to Daoist teachings, Chongxuan thinkers generally admitted the existence of social and spiritual inequality between humans, which they explain as divergence on the part of the Dao or Taiyi universal force received at birth, and by the interplay of qi, both of which depended on circumstances.
