1.23

Sixth, harmonizing the contradictions among the sūtras and treatises, broadly presenting questions and answers, and dispelling doubts. Within this section, there are six topics: first, presenting the various Dharma masters' explanations of the meaning of the nine grades; second, refuting them using reasoning; third, raising the nine grades again to counter and refute them; fourth, citing scriptural passages to prove that it is definitively for pṛthagjanas and not for noble beings; fifth, reconciling the intended meaning of 'a different time'; sixth, reconciling the meaning that the lineage of the two vehicles is not born [there].
