大乘義章 1.46

1.46

第三常沒，喻外凡夫。暫出還沒，喻五停心總別念處。住者，喻於四賢忍心。觀方，喻於四沙門果。觀已行者，喻於緣覺，觀四諦已趣入因緣。行已住者，喻於菩薩，捨離煩惱，故名為行；為化眾生，不捨三有，因之為住。水陸俱行，喻於如來（此三門竟）。

Third, constantly submerged illustrates the external ordinary person. Emerging temporarily and submerging again illustrates the fivefold mental stabilities and the collective and distinct applications of mindfulness. Standing firm illustrates the mind of forbearance of the four virtuous states. Looking around in all directions illustrates the four fruits of śramaṇahood. Walking after looking around illustrates the pratyekabuddha, who, having contemplated the four noble truths, proceeds to enter into dependent origination. Standing firm after walking illustrates the bodhisattva: relinquishing afflictions, they are therefore termed 'walking'; for the sake of transforming sentient beings, they do not abandon the three realms of existence, and on this basis are termed 'standing firm'. Traversing both water and land illustrates the Tathāgata. (This completes the third gateway.)
