The emperor also decided to discredit the Nara Buddhists on their own terms, sending to China for new, competing sects. Back came emissaries with two new schools, which soon assumed dominance of Japanese Buddhism. The first of these was Tendai, named after the Chinese T'ien-t'ai school. Its teachings centered on the Lotus Sutra, which taught that the human Buddha personified a universal spirit, evidence of the oneness permeating all things. The Tendai school was installed on Mt. Hiei, in the outskirts of Kyoto, giving birth to an establishment eventually to number several thousand buildings. The monks on Mt. Hiei became the authority on Buddhist matters in Japan for several centuries thereafter, and later they also began meddling in affairs of state, sometimes even resorting to arms. Tendai was, and perhaps to some degree still is, a faith for the fortunate few. It did not stress an idealized hereafter, since it served a class—the idle aristocracy—perfectly comfortable in the present world. In any case, it became the major Japanese Buddhist sect during the Heian era (794-1185), a time of aristocratic rule.
The other important, and also aristocratic, version of Buddhism preceding Zen was called Shingon, from the Chinese school Chen-yen, a magical-mystery sect thriving on secrecy and esoteric symbolism. It appealed less to the intellect than did Tendai and more to the taste for entertainment among the bored aristocrats. Although Shingon monasteries often were situated in remote mountainous areas, the intrigue of their engaging ceremonies (featuring efflorescent iconography, chants, and complex liturgies) and their evocative mandalas (geometrical paintings full of symbolism) made this sect a theatrical success. This so-called Esoteric Buddhism of Shingon grew so popular that the sober Tendai sect was obliged to start adding ritualistic complexity into its own practices.4
The Japanese government broke off relations with China less than a hundred years after the founding of Kyoto, around the middle of the ninth century. From then until the mid-twelfth century mainland contacts virtually ceased, and consequently both Japanese culture and Japanese Buddhism gradually evolved away from their Chinese models. The Japanese aristocracy became obsessed with aesthetics, finery, and refined lovemaking accompanied by poetry, perfumes, and flowers.5 They distilled the vigorous T'ang culture to a refined essence, rather like extracting a delicate liqueur from a stout potion.
The Buddhist church also grew decadent, even as it grew ever more powerful and ominous. The priesthood became the appointment of last resort for otherwise unemployable courtiers, and indeed Buddhism finally degenerated largely into an entertainment for the ruling class, whose members were amused and diverted by its rites. This carefree aristocracy also allowed increasing amounts of wealth and land to slip into the hands of corrupt religious establishments. For their own part, the Buddhists began forming armies of monks to protect their new wealth, and they eventually went on to engage in inter-temple wars and threaten the civil government.
During this time, the Japanese aristocracy preserved its privileged position through the unwise policy of using an emerging military class to maintain order. These professional soldiers seem to have arisen from the aristocacy itself. Japanese emperors had a large number of women at their disposal, through whom they scattered a host of progeny, not all of which could be maintained idle in Kyoto. A number of these were sent to the provinces, where they were to govern untamed outlying areas. This continued until one day the court in Kyoto awoke to find that Japan was in fact controlled by these rural clans and their mounted warriors, the samurai.6
In the middle of the twelfth century, the samurai effectively seized Japan, and their strongman invented for himself the title of shogun, proceeding to institute what became almost eight centuries of unbroken warrior rule. The age of the common man had arrived, and one of the shogun's first acts was to transfer the government away from aristocratic Kyoto, whose sophisticated society made him uncomfortable, to a warrior camp called Kamakura, near the site of modern Tokyo. The rule of Japan passed from perfumed, poetry-writing aesthetes to fierce, often illiterate swordsmen.
Coincident with this coup, the decadence and irrelevance of traditional Buddhism had begun to weigh heavily upon a new group of spiritual reformers. Before long Tendai and Shingon were challenged by new faiths recognizing the existence and spiritual needs of the common people. One form this reformation took was the appearance of new sects providing spiritual comfort to the masses and the possibility of eternal salvation through some simple act, usually the repetition of a sacred chant. One, and later two, such sects (Jodo and Jodo Shin) focused on the Buddhist figure Amida, whose Paradise or "Pure Land" in the hereafter was open to all those calling upon his name (by chanting a sort of Buddhist "Hail Mary" called the nembutsu, "Praise to Amida Buddha"). Another simplified sect preached a fundamentalist return to the Lotus Sutra and was led by a firebrand named Nichiren, who also created a chant for his largely illiterate followers. A formula guaranteeing Paradise had particular appeal to the samurai, whose day-to-day existence was dangerous and uncertain. The scandalized Tendai monks vigorously opposed this home-grown populist movement, occasionally even burning down temples to discourage its growth. But the Pure Land and Nichiren sects continued to flourish, since the common people finally had a Buddhism all their own.
There were others, however, who believed that the aristocratic sects could be reformed from within—by importing them afresh from China, from the source. These reformers hoped that Buddhism in China had maintained its integrity and discipline during the several centuries of separation. And by fortunate coincidence, Japanese contacts with the mainland were being reopened, making it again allowable to undertake the perilous sea voyage to China. But when the first twelfth-century Japanese pilgrims reached the mainland, they were stunned to find that traditional Buddhism had been almost completely supplanted by Ch'an. Consequently, the Japanese pilgrims returning from China perforce returned with Zen, since little else remained. However, Zen was not originally brought back to replace traditional Buddhism, but rather as a stimulant to restore the rigor that had drained out of monastic life, including formal meditation and respect or discipline.7
Credit for the introduction of Lin-chi Zen (called Rinzai) in Japan is traditionally given to the aristocratic priest and traveler Myoan Eisai (1141-1215).8 He began his career as a young monk in the Tendai complex near Kyoto, but in the summer of 1168 he accompanied a Shingon priest on a trip to China, largely to sightsee and to visit the home of the T'ien-t'ai sect as a pilgrim. However, the T'ien-t'ai school must have been a mere shadow of its former self by this time, and naturally enough Eisai became familiar with Ch'an. But he was hardly a firebrand for Zen, for when he returned to Japan he continued practice of traditional Buddhism.
Some twenty years later, in 1187, Eisai again journeyed to China, this time planning a pilgrimage on to India and the Buddhist holy places. But the Chinese refused him permission to travel beyond their borders, leaving Eisai no choice but to study there. He finally attached himself to an aging Ch'an monk on Mt. T'ien-t'ai and managed to receive the seal of enlightenment before returning to Japan in 1191, quite probably the first Japanese ever certified by a Chinese Ch'an master. He was not, however, totally committed to Zen. His Ch'an teacher was also occupied with other Buddhist schools, and what Eisai brought back was a Buddhist cocktail blended from several different traditions.9 But he did proceed to build a temple to the Huang-lung (Japanese Oryo) branch of the Lin-chi sect on the southernmost Japanese island, Kyushu (the location nearest China), in the provincial town of Hakata. Almost as important, he also brought back the tea plant (whose brew was used in China to keep drowsy monks awake during meditation), thereby instituting the long marriage of Zen and tea.
