二、徵釋四事，二：初、徵起。二、答釋，四：初、釋經初六事。「為斷疑勸信」者，結集時阿難登高，而形相似佛，眾疑釋尊重出、或他方佛來、或阿難成佛。若唱我聞，三疑皆遣，故云斷疑。「勸信」者，信為能入，智為能度。不信言是事不如是，信者言是事如是故。「是謂吉相」者，初標吉相，以表經中皆吉。「具如百論」者，《法華疏記》第一備引之。

Second, interrogating and explaining the four matters, in two: first, raising the interrogation. Second, answering and explaining, in four: first, explaining the initial six matters of the sūtra. Regarding "to sever doubts and encourage faith": at the time of the compilation, Ānanda ascended the high seat, and his form resembled the Buddha. The assembly doubted whether Śākyamuni had reappeared, or a Buddha from another land had arrived, or Ānanda had attained Buddhahood. When he proclaimed "Thus have I heard", the three doubts were all dispelled; hence it says "sever doubts". Regarding "encourage faith": faith enables entry, and wisdom enables crossing over. The unbelieving say "this matter is not so", whereas the faithful say "this matter is so". Regarding "this is called an auspicious sign": initially marking an auspicious sign expresses that throughout the sūtra all is auspicious. Regarding "fully as in the Śata-śāstra": the Lotus Sūtra Commentary and Subcommentary, fascicle one, cites it completely.
