He expounded to us the teaching of emancipation. We obtained this teaching and reached Nirvāṇa. We do not know why he says all this. (Hurwitz translation: The Buddha has preached the doctrine of unique deliverance, which means that we, too, gaining this Dharma, shall reach nirvana. Yet now we do not know where this doctrine tends.”)

Even though there is distinction between superior and inferior in the merits and virtues of the three vehicles, there ultimately is no difference in that they all reach the abode of the eternal cessation of nirvana. Hence, it is said, “unique deliverance” (ekaiva vimuktir), “unique” (or “one”) meaning “the same.” But they do not “know where the doctrine tends’? that the Buddha praised in such utmost earnest.
