In 1931 and 1932, Debating on the difference of Yogacara latter philosophy and Yogacara former philosophy, Venerable Yin Shun started to study on Mahayana-sajparigraha-wastra school. Venerable Yin Shun gradually set up the interpretation standpoint of Middle-way to Mahayana-sajparigraha-wastra school. In his book the Lecture sheets of Mahayana-sajparigraha-wastra, and Discussion with Mao Zong-san, Venerable Yin Shun insisted fully on the Middle-way. However, in Venerable Yin Shun’s later years, He published the article Qi-xin-lun and Fu-nan maha-yana, which indicated that he abandoned the Middle-way and selected the interpretation standpoint of original Enlightened of Qi-xin-lun. The change of Venerable Yin Shun’s Middle-way tallied with the development of thought history of Mahayana-sajparigraha-wastra school. We can find the thought history from the Mahayana-sajparigraha-wastra school to Qi-xin-lun, and we must study and inherit it.
