勝鬘寶窟 3.3

3.3

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.
