摩訶止觀 3.152

3.152

若圓教教、證，俱不思議。何故爾？至理無說，為緣四說；但有假名，假名之名，名即無生。故教、證俱不可思議也。無思無念，故無依倚、戲論、結業，無業故無生死，是名自行為得。得於實體，能以不可說說，化導眾生，令出生死，得於實體，是為自、他俱得體也。

In the perfect teaching, both teaching and realization are inconceivable. Why is this? The ultimate principle is beyond expression, yet for the sake of conditions there are four expositions; there are only provisional designations, and the designation of a provisional designation is fundamentally unarisen. Therefore both teaching and realization are inconceivable. Free of thought and reflection, there is no reliance, conceptual proliferation, or bound karma; without karma there is no birth and death—this is called attainment in self-cultivation. Having attained the real substance, one is able to expound with the ineffable to transform and guide sentient beings, causing them to transcend birth and death and attain the real substance—this is attaining the substance for both oneself and others.
