法華玄論 6.44

6.44

Answer: That the Buddha vehicle exists is an ultimate meaning. However, [teachings] differ as to whether what is taught of that existence is exhaustive or inexhaustive; hence there are the ultimate and the non-ultimate. Former teachings explained the Buddha vehicle incompletely, while the present teaching clarifies the Buddha vehicle completely. The Commentary [to the Mahāprajñāpāramitā-śāstra] says: "The Buddha did not fully explain the Buddha's merits within the Tripiṭaka, for roughly three reasons: First, it is incomplete in terms of existence and non-existence, as the Tripiṭaka does not speak of the eighteen unique qualities and so forth, which are spoken of only in the Mahāyāna. Second, it is incomplete because the explanation is not exhaustive, as the Tripiṭaka speaks of the ten powers but does not mention exhaustive knowledge and universal knowledge; that exhaustive knowledge and universal knowledge are mentioned is merely the explanation of treatise masters. Third, it is incomplete because within a single category it explains half and omits half, as the Tripiṭaka clarifies only three eyes, while the Mahāyāna sūtras fully explain the five eyes."
