(19) The contents of the Mahayana sutras often prove that they were, composed, or rewritten, or some additions were made, long after the Buddha. For instance, Mahamaya-sutra says that Acvaghosa would refute heretical doctrines 600 years after the Master, and Nagarjuna would advocate the Dharma 700 years after Gotama, while Lankavatara-sutra prophesies that Nagarjuna would appear in South India.

(20) The author of San-ron-gen-gi tells us Mahadeva, a leader of the Mahasamghika School, used Mahayana sutras, together with the orthodox Tripitaka 116 after the Buddha. It is, however, doubtful that they existed at so early a date.

(21) Mahaprajnaparamita-castra, ascribed to Nagarjuna, refers to many Mahayana books, which include Saddharma-pundarika, Vimalakirtti-nirdeca, Sukhavati-vyuha, Mahaprajnaparamita, Pratyutpanna-buddhasammukhavasthita-samadhi, etc. He quotes in his Dacabhumivibhasa castra, Mahaparinirvana, Dacabhumi, etc.

(22) Sthiramati, whose date is said to be earlier than Nagarjuna and later than Acvaghosa, tries to prove that Mahayanism was directly taught by the Master in his Mahayanavataraka-castra. And Mahayanottaratantra-castra, which is ascribed by some scholars to him, refers to Avatamsaka, Vajracchedikka-prajnaparamita, Saddharmapundarika, Crimala-devi-simhananda, etc.

(23) Chi-leu-cia-chin, who came to China in A.D. 147 or A.D. 164, translated some part of Mahayana books known as Maharatnakuta-sutra and Mahavaipulya-mahasannipata-sutra.

(24) An-shi-kao, who came to China in A.D. 148, translated such Mahayana books as Sukhavati-vyaha, Candra-dipa-samadhi, etc.

(25) Matanga, who came to China in A.D. 67, is said by his biographer to have been informed of both Mahayanism and Hinayanism to have given interpretations to a noted Mahayana book, entitled Suvarnaprabhasa.

(26) Sandhinirmocana-sutra is supposed to be a work of Asanga not without reason, because Asanga's doctrine is identical with that of the sutra, and the sutra itself is contained in the latter part of Yogacaryabhumi-castra. The author divides the whole preachings of the Master into the three periods that he might place the Idealistic doctrine in the highest rank of the Mahayana schools.

(27) We have every reason to believe that Mahayana sutras began to appear (perhaps Prajna sutras being the first) early in the first century A.D., that most of the important books appeared before Nagarjuna, and that some of Mantra sutras were composed so late as the time of Vajrabodhi, who came to China in A.D. 719.]

opposition raised by the Japanese scholars,[1] such an assumption can be met with an assumption of entirely opposite nature, and the difficulties can never be overcome. For Zen masters, therefore, these assumptions and reasonings are mere quibbles unworthy of their attention.
