Distinguishing the Middle From the Extremes, Karmê Chöling and Kagyu Thubten Choling 1990 དབུས་དང་མཐའ་རྣམ་པར་འབྱེད་པ།

To perceive and to settle, as well as to continue, / To experience, two types of purity are the reason.

Another case is that where the result / No longer is susceptible to experience, / That where the causes no longer are experienced, / And likewise that where neither has transpired.

The feelings plus their causal constituents; / The cause of this provides the producing factor, / Which is the truth of the origin of it all. / There is also an utter pacification of these / And that whose role is to act as the remedy; / And therefore, this is considered a separate point.
