勝鬘寶窟 3.3

3.3

「何以故」下，第二問答辨釋。「何以故」者，問也。二乘與佛乘異，何由能得無上菩提？下對釋之。彰彼二乘同入大乘，故得菩提。依《法華論》，三乘人法身無異，是故三乘同入一乘。又說一為三，故三是一也。問：大乘一乘，云何同異？答：有人言大乘通因果，一乘唯是果。今明此中是異名，或名大乘、或名一乘。但顯所入一乘是佛乘，故是究竟。

From "Why is this?" onward is the second [section], which analyses and explains by question and answer. "Why is this?" is the question: since the two vehicles differ from the buddhayāna, how could they attain anuttarasamyaksaṃbodhi? Below, it responds and explains it: by demonstrating that those two vehicles together enter the Mahāyāna, they therefore attain bodhi. According to the Saddharmapuṇḍarīkopadeśa, the dharmakāya of persons of the three vehicles does not differ; therefore the three vehicles together enter the ekayāna. Furthermore, the one is taught as three, and therefore the three are the one. Question: What is the sameness and difference between the Mahāyāna and the ekayāna? Answer: Some say that the Mahāyāna runs through both cause and fruition, whereas the ekayāna is solely fruition. Now it is explained that here they are different names [for the same thing], termed either Mahāyāna or ekayāna. It merely reveals that the ekayāna which is entered is the buddhayāna, and is therefore ultimate.
