concrete images of Thai Buddhas, the [Chinese] Jade Emperor and Siva with the tiger. Temple staff of the three religions attend to their own altars and help devotees as and when required.
The most widespread Buddhist images seen throughout China which are obviously not Chinese deities are the four major guardians in the entrance hall to Buddhist establishments, the Defenders of the Faith. These and other similar minor guardian deities are former gods of Indian folklore and include the giant guardian deities known in Chinese as Wu-shih, such as those whose images stand outside the main hall of the Jinci in Taiyuan. A further two are the traditional guardians of Buddhist temple gates dating from at least the 8th century. The one [facing the gate] on the right hand is opened-mouthed and coloured vermilion, whilst the guardian on the left has a closed-mouth and is the colour of charcoal. Both are made of stucco. In China they are known as the two generals Heng and Ha, the Blower and the Snorter. In legend they fought with secret weapons; one blew a deadly yellow gas from his mouth with a ha! and the second snorted a white beam of light from each nostril with a heng! which vaporised his enemies. They can also be seen guarding the entrances to Japanese Buddhist temples where they are known as Kongo Rikishi. All of these guardians are undeniably foreign in form in comparison with the gilded images of the standard Buddhas which are now not even considered by Chinese devotees to be anything but Chinese.
We know who the Deva are, when they were placed in their present temples, both in Taiwan and the Western Hills, but not why. From our various sources it would seem that these Sinicised Indian deities are celestial protectors. We can guess that the concept was imported at a comparatively late stage but who, individually, sponsored them and had the images made is now lost in time. It is interesting to note that present day monks in the Western Hills have little idea of their origins and were apparently completely disinterested in the subject.
In the cave-tunnel in the comparatively modern temple in Taiwan, however, the images were, to the religious specialists there, simply Buddhas of Yore, the principal ones who preceded Sakyamuni.
