注大乘入楞伽經 6.111

6.111

This clarifies that the three realms are illusory and unreal, and that the self and all phenomena are entirely without actual reality. It states that there are four kinds of sameness: the mark of conditioned phenomena is the sameness of impermanence; the causes of defilement are the sameness of suffering; all produced phenomena are empty and unreal; and the sameness of non-self—these are the four samenesses. Practitioners should constantly and diligently contemplate them.
