宋高僧傳 3.51

3.51

「又傳譯之興，奉行之意，不明本起，何示將來？今究其宣揚，略陳梗概。夫教者不倫，有三疇類：一顯教者，諸乘經、律、論也（不同《瑜伽論》中『顯了教，是多分大乘藏教。』）；二密教者，瑜伽、灌頂、五部、護摩、三密、曼拏羅法也（《瑜伽》『隱密教，是多分聲聞藏教。』）；三心教者，直指人心，見性成佛，禪法也。次一法輪者，即顯教也，以摩騰為始祖焉；次二教令輪者，即密教也，以金剛智為始祖焉；次三心輪者（義加此輪），即禪法也，以菩提達磨為始祖焉。是故傳法輪者以法音傳法音；傳教令輪者，以祕密傳祕密；傳心輪者，以心傳心，此之三教、三輪、三祖，自西而東，化凡而聖，流十五代（漢、魏、晉、宋、齊、梁、陳、隋、唐、朱梁、後唐、石晉、劉漢、郭周、今大宋），法門之貽厥孫謀，萬二千年，真教之克昌厥後。」

"Furthermore, regarding the rise of translation and the intention of its transmission, if the origins are not clarified, how can the future be shown? Now, investigating its propagation, I briefly set forth the outline. Teachings are varied, having three categories: 1. Exoteric teachings: the sūtras, vinaya, and śāstras of the various vehicles (differing from the Yogācārabhūmi-śāstra's 'explicit teaching is mostly the Bodhisattva-piṭaka teaching'); 2. Esoteric teachings: yoga, consecration (abhiṣeka), the five divisions, homa, the three mysteries, and maṇḍala rituals (in the Yogācārabhūmi, 'implicit teaching is mostly the Śrāvaka-piṭaka teaching'); 3. Mind teaching: directly pointing to the human mind, seeing one's nature to become a Buddha—the dhyāna method. The first wheel of the Dharma is the exoteric teaching, taking Kāśyapa Mātaṅga as its founding patriarch; the second, the command wheel (ājñā-cakra), is the esoteric teaching, taking Vajrabodhi as its founding patriarch; the third, the mind wheel (added here on the basis of its meaning), is the dhyāna method, taking Bodhidharma as its founding patriarch. Therefore, those who transmit the wheel of the Dharma transmit the sound of Dharma by means of the sound of Dharma; those who transmit the command wheel transmit the secret by means of the secret; those who transmit the mind wheel transmit mind with mind. These three teachings, three wheels, and three patriarchs, coming from west to east, converting ordinary beings into sages, have flowed through fifteen dynasties (Han, Wei, Jin, Song, Qi, Liang, Chen, Sui, Tang, Later Liang, Later Tang, Later Jin, Later Han, Later Zhou, and now the Great Song); the bequeathing of these dharma-gates' grand plans to descendants will ensure that for twelve thousand years the true teaching will flourish among their successors."
