○十九、斷無法如何修證疑。論云「如來不得一法，云何離上上證轉，轉得阿耨菩提？為斷此疑，示現非證法，名為阿耨菩提。」

19. Severing the doubt: 'If there is no dharma, how does one cultivate and realize it?' The treatise states: 'If the Tathāgata does not attain a single dharma, how does he, apart from successively higher realizations, successively attain anuttarā-[samyak-sam]bodhi? To sever this doubt, it is demonstrated that non-realization of dharma is called anuttarā-[samyak-sam]bodhi.'
