The principal works in class 4 are two translations, one fuller than the other, of the Hua-yen or Avatamsaka Sûtra[714], still one of the most widely read among Buddhist works, and at least sixteen of the other items are duplicate renderings of parts of it. Class 5 consists of thirteen works dealing with the death of the Buddha and his last discourses. The first sûtra, sometimes called the northern text, is imperfect and was revised at Nanking in the form of the southern text[715]. There are two other incomplete versions of the same text. To judge from a specimen translated by Beal[716] it is a collection of late discourses influenced by Vishnuism and does not correspond to the Mahâparinibbânasutta of the Pali Canon. Class 6 consists of sûtras which exist in several translations, but still do not, like the works just mentioned, form small libraries in themselves. It comprises, however, several books highly esteemed and historically important, such as the Saddharmapuṇḍarîka (six translations), the Suvarṇaprabhâsa, the Lalitavistara, the Lankâvatâra, and the Shorter Sukhâvatîvyûha[717], all extant in three translations. In it are also included many short tracts, the originals of which are not known. Some of them are Jâtakas, but many[718] deal with the ritual of image worship or with spells. These characteristics are still more prominent in the seventh class, consisting of sûtras which exist in a single translation only. The best known among them are the Śûrângama and the Mahâvairocana (Ta-jih-ching), which is the chief text of the Shin-gon or Mantra School[719]. The Lü-tsang or Vinaya-pitaka is divided into Mahâyâna and Hînayâna texts, neither very numerous. Many of the Mahâyâna texts profess to be revelations by Maitreya and are extracts of the Yogâcâryabhûmiśâstra[720] or similar to it. For practical purposes the most important is the Fan-wang-ching[721] or net of Brahmâ. The Indian original of this work is not known, but since the eighth century it has been accepted in China as the standard manual for the monastic life[722].
