51.6

第三宗趣。頓彰六位理事二離為宗，令體性離頓成真離究竟為趣。

Third, the main doctrine and purport: taking the sudden revelation of both noumenal and phenomenal leaving throughout the six stations as its main doctrine, and causing the fundamental nature of leaving to be suddenly accomplished as true leaving in its ultimacy as its purport.
