「除前三種至合成第四」者，釋四餘生三時不知。又《婆沙》一百七十二云「有說：第四入胎謂菩薩，第三入胎謂獨覺，第二入胎謂輪王，第一入胎謂餘有情。有說：第四入胎謂菩薩，第三入胎謂獨覺，第二入胎謂波羅蜜多聲聞，第一入胎謂餘有情。有說：第四入胎謂菩薩，第三入胎謂獨覺，第二入胎謂預流、一來，第一入胎謂餘有情。」如彼廣說。又云「復次此四種入胎皆謂菩薩。於中有說：第四入胎是第三阿僧祇耶菩薩，第三入胎是第二阿僧祇菩薩，第二入胎是初阿僧企耶菩薩，第一入胎是此前菩薩。」更有說，非是正義，評家自破。如彼廣說。

"Excepting the preceding three kinds […] combined, they form the fourth": this explains that the remaining births are unknowing at the three times. Furthermore, the Mahāvibhāṣā, fascicle 172, states: "Some say: The fourth entering the womb refers to the bodhisattva; the third entering the womb refers to the pratyekabuddha; the second entering the womb refers to the wheel-turning monarch; the first entering the womb refers to other sentient beings. Some say: The fourth entering the womb refers to the bodhisattva; the third entering the womb refers to the pratyekabuddha; the second entering the womb refers to a śrāvaka of the pāramitās; the first entering the womb refers to other sentient beings. Some say: The fourth entering the womb refers to the bodhisattva; the third entering the womb refers to the pratyekabuddha; the second entering the womb refers to stream-enterers and once-returners; the first entering the womb refers to other sentient beings." As is extensively explained there. It also states: "Furthermore, these four kinds of entering the womb all refer to the bodhisattva. Among them, some say: The fourth entering the womb is the bodhisattva of the third asaṃkhyeya; the third entering the womb is the bodhisattva of the second asaṃkhyeya; the second entering the womb is the bodhisattva of the first asaṃkhyeya; the first entering the womb is the bodhisattva prior to this." There are further explanations that are not the orthodox doctrine, which the evaluator himself refutes, as is extensively explained there.
