釋禪波羅蜜次第法門 8.40

8.40

次釋「觀於心性」者，即是返觀能思惟、大思惟之心也。所以者何？行者雖能了於前境，而不能返達觀心，則不會實道。今即返照能觀之心，為從觀心生，為從非觀心生？若從觀心生，若從非觀心生，二俱有過，當知觀心畢竟空寂。五句釋覺支竟。

Next, explaining 'observing the nature of the mind': this is turning back to observe the mind that is capable of reflection and great reflection. Why is this? Although the practitioner can understand the preceding objects, if he cannot turn back and penetrate the observing mind, he will not tally with the true path. Now he turns back to illuminate the mind capable of observing: does it arise from an observing mind, or does it arise from a non-observing mind? Whether it arises from an observing mind or arises from a non-observing mind, both have faults; one should know that the observing mind is ultimately empty and tranquil. The explanation of the vitarka factor through five phrases is finished.
