妙法蓮華經玄義 4.147

4.147

五、明身證位者，還是信解、見到二人，入思惟道，用無漏智，斷上下分結，發四禪、四無色定。即是用共念處，修八背捨、八勝處、十一切處，入九次第定。三空事、性兩障先已斷盡，又斷非想事障，滅緣理諸心、心數法，入滅盡定。得此定故，名身證阿那含也。何者？入滅定似涅槃法，安置身內，息三界一切勞務。身證想受滅，故名身證也。

Fifth, clarifying the stage of bodily realization: again, it is the two persons of understanding through faith and vision-attained who enter the path of cultivation, use untainted wisdom to sever the lower and higher fetters, and give rise to the four dhyānas and the four formless concentrations. That is, using shared stations of mindfulness, they cultivate the eight liberations, the eight stations of mastery, and the ten stations of totality, entering the nine sequential concentrations. Having previously severed both the phenomenal and essential hindrances of the three emptinesses, they further sever the phenomenal hindrances of neither-perception-nor-non-perception, extinguish all mind and mental factors directed at the principle, and enter the concentration of cessation. Because they attain this concentration, they are called bodily-realized anāgāmins. Why? Entering the concentration of cessation resembles the phenomenon of nirvāṇa, settling it within the body and tranquilizing all toil of the three realms. Through the body they realize the cessation of perception and sensation; hence it is called 'bodily realization'.
