This situation led to the famous debate within the Tiantai school known as the home mountain (shanjia) vs. off mountain (shanwai) debate. Off mountain supporters, as they were later polemically termed, supported these new doctrines (such as the one pure mind) claiming they were originally Tiantai doctrines, while home mountain supporters saw the original Tiantai view as different and superior to this new view influenced by Chan and Huayan doctrines (especially by Zongmi's works). The most eminent figure during this debate was Patriarch Siming Zhili (960-1028), who wrote various commentaries on Zhiyi's works and defended the Home mountain view. Zhili's major criticisms included attacking Chan's failure to understand the necessity of the use of words and scriptural study as part of practice as well as criticizing Zongmi's view of a pure mind as the buddha-nature, arguing instead that the three truths as taught by Zhiyi are the ultimate reality. For Zhili, mind or consciousness has no special status relative to other types of dharmas, such as physical matter.
