妙法蓮華經玄義 5.131

5.131

六、類通三大乘者，真性即理乘；觀照即隨乘；資成即得乘。故下文云：「佛自住大乘，如其所得法，定慧力莊嚴。」住大乘即理乘；定慧莊嚴即隨乘；所得法即得乘。「佛自住大乘」是理乘；「於道場知已」是隨乘；「導師方便說」是得乘。又「舍利弗！以本願故，說三乘法。」是得乘、隨乘。又，「是乘微妙清淨第一」是理乘。「於一佛乘」是理乘；「分別說三」是得乘、隨乘。不縱不橫妙，開麁妙、歷七位（云云）。五品，名字乘。六根，相似乘。四十一位，分真乘。妙覺，究竟乘（云云）。

Sixth, subsuming and identifying with the three Great Vehicles: true nature is the principle vehicle; contemplative illumination is the attendant vehicle; auxiliary conditions are the attained vehicle. Therefore the text below states: "The Buddha himself abides in the Great Vehicle; according to the Dharma he has attained, it is adorned with the power of concentration and wisdom." Abiding in the Great Vehicle is the principle vehicle; adorned with concentration and wisdom is the attendant vehicle; the Dharma attained is the attained vehicle. "The Buddha himself abides in the Great Vehicle" is the principle vehicle; "Having known it at the place of enlightenment" is the attendant vehicle; "The Guide preaches using expedients" is the attained vehicle. Furthermore, "Śāriputra, because of my original vow, I preach the three-vehicle Dharma"—this refers to the attained vehicle and the attendant vehicle. Furthermore, "This vehicle is subtle, wondrous, pure, and foremost" is the principle vehicle. "In the one buddha-yāna" is the principle vehicle; "distinguishing and expounding the three" is the attained vehicle and the attendant vehicle. Neither vertical nor horizontal is wondrous; opening the crude is wondrous; running through the seven ranks (and so forth). In the five stages, the nominal vehicle. In the six sense-faculties, the semblance vehicle. In the forty-one ranks, the partial-real vehicle. In wondrous enlightenment, the ultimate vehicle (and so forth).
