In the Heian centuries the kami and the buddhas were not rivals but partners. Shrines housed sutra readings, temples enshrined kami as their protectors, and the doctrine of honji suijaku taught that the kami are the local traces of universal buddhas, manifest in Japan to save its people. This fusion, shinbutsu-shūgō, was the ordinary religion of Japan for a thousand years: a villager saw no seam where later ages would insist on cutting one, and the great shrine-temples, like Kasuga with its temple Kōfukuji, embodied the union.

How the Tradition Tells It
The fusion was never total or uniform. Court and mountain centres elaborated the combinations; many local shrines simply carried on. And the age produced its own dissenters: the Ise priesthood guarded a kami teaching kept apart from the temples centuries before separation had a name.
