大般涅槃經義記 6.55

6.55

前中，初問，次辯，後結。辯中，「知生信心成」者，解前若心求於大乘，斷前若根，依根趣法，故說為求。乘、根別所趣各異，今舉求大，小略不論。「是人順」等解於向前若禪、若乘，順流是禪，逆流正住及與到岸是前乘也。修世八禪是凡夫法，隨順生死故名順流；修習聖道，出離生死，故名逆流，乃至到岸。下辯可知。

In the former, there is first a question, next an analysis, and finally a conclusion. In the analysis, "knowing that the generation of the mind of faith is accomplished" explains the previous "if the mind seeks the Mahāyāna"; it cuts off the previous "if the faculties"; relying on faculties to proceed toward dharmas is therefore called seeking. The vehicle and faculties differ, and what is proceeded toward is diverse; here it mentions seeking the Mahāyāna, leaving aside the Hīnayāna. "This person follows [the stream]," and so forth, explains the preceding "if dhyāna, if the vehicle": following the stream is dhyāna; going against the stream, standing upright, and reaching the shore are the previous vehicle. Cultivating the eight mundane dhyānas is the dharma of ordinary persons; conforming to birth and death, it is therefore called following the stream. Cultivating the noble path to transcend birth and death is therefore called going against the stream, up to reaching the shore. The explanation below may be understood.
