I-Ching also tells us of the ceremonial bathing of images and prefaces his description by the remark that "the meaning of the Truths is so profound that it is a matter beyond the comprehension of vulgar minds while the ablution of the holy images is practicable for all. Though the Great Teacher has entered Nirvana yet his image exists and we should worship it with zeal as though in his presence. Those who constantly offer incense and flowers to it are enabled to purify their thoughts and those who perpetually bathe his image are enabled to overcome the sins that involve them in darkness."[261] He appears to contemplate chiefly the veneration of images of Sâkyamuni but figures of Bodhisattvas were also conspicuous features in temples, as we know not only from archæology but from the biography of Hsüan Chuang, where it is said that worshippers used to throw flowers and silk scarves at the image of Avalokita and draw auguries from the way they fell.
Monasteries were liberally decorated with statues, carvings and pictures.[262] They often comprised several courts and temples. Hsüan Chuang says that a monastery in Magadha which he calls Ti-lo-shi-ka had "four courts with three storeyed halls, lofty terraces and a succession of open passages.... At the head of the road through the middle gate were three temples with disks on the roof and hung with small bells; the bases were surrounded by balustrades, and doors, windows, beams, walls, and stairs were ornamented with gilt work in relief." In the three temples were large images representing the Buddha, Târâ and Avalokita.
The great centres of Buddhist learning and monastic life, mentioned by both pilgrims, were Valabhî or Balabhi in Gujarat and Nalanda. The former was a district rather than a single locality and contained 100 monasteries with 6000 monks of the Sammitîya school. Nalanda was in Magadha not far from Gaya. The date of its foundation is unknown but a great temple (though apparently not the first) was built about 485 A.D.[263] Fa-Hsien mentions a village called Nala but without indicating that it was a seat of learning. Hence it is probable that the University was not then in existence or at least not celebrated. Hsüan Chuang describes it as containing six monasteries built by various kings and surrounded by an enclosing wall in which there was only one gate. I-Ching writing later says that the establishment owned 200 villages and contained eight halls with more than 3000 monks. In the neighbourhood of the monastery were a hundred sacred spots, several marked by temples and topes. It was a resort for Buddhists from all countries and an educational as well as a religious centre. I-Ching says that students spent two or three years there in learning and disputing after which they went to the king's court in search of a government appointment. Successful merit was rewarded not only by rank but by grants of land. Both pilgrims mention the names of several celebrities connected with Nalanda. But the worthies of the seventh century did not attain to more than scholastic eminence. The most important literary figure of the age is Sântideva of whose life nothing is known. His writings however prove that the Buddhism of this period was not a corrupt superstition, but could inspire and nourish some of the most beautiful thoughts which the creed has produced.
