大方廣佛華嚴經隨疏演義鈔 9.30

9.30

Regarding the commentary's "These three also accord with the four vehicles": the first is the Hīnayāna, and the next is the triyāna; both of these two are subsumed under the triyāna teachings, because the initial Hīnayāna is the Hīnayāna within the triyāna. The latter three are the one vehicle, and thus they constitute the four vehicles. Furthermore, from "Liang treatise" downward, it validates the meaning of the three and the one. It was already cited in the previous text harmonising the triyāna and the one vehicle, and along with the Miaozhi jing and the Bu yizhi ji, all are as cited previously.
