第二、明以法驗知邪正者，自有邪禪，其相微細難別，與正禪相似，非則相之所能別，應以三法驗知：一、定心研磨；二、用本法修治；三、智慧破析。

Second, explaining the verification and discernment of the corrupt and the correct by means of the Dharma: There are corrupt dhyānas whose marks are subtle and hard to distinguish, resembling correct dhyāna, which cannot be distinguished merely by their marks. They should be verified and known by three methods: first, grinding with a concentrated mind; second, cultivating and rectifying with the original practice; third, refuting and analyzing with wisdom.
