Eisai was the classic tactician, knowing well when to fight and when to retire, and he decided in 1199 on a diversionary retreat to Kamakura, leaving behind the hostile, competitive atmosphere of aristocratic Kyoto. Through his political connections, he managed to get installed as head of a new temple in Kamakura, beginning Zen's long association with the Japanese warrior class. Eisai seems to have done well in Kamakura, for not long after he arrived, the current strongman gave him financing for a Zen temple in Kyoto, named Kennin-ji and completed in 1205. Eisai returned the favor by assisting in the repair of temples ravaged by the recent wars. It was reportedly for a later, hard-drinking ruler that Eisai composed his second classic work, "Drink Tea and Prolong Life," which championed the medicinal properties of this exotic Chinese beverage, declaring it a restorative that tuned up the body and strengthened the heart. _In the great country of China they drink tea, as a result of which there is no heart trouble and people live long lives. Our country is full of sickly-looking, skinny persons, and this is simply because we do not drink tea. Whenever one is in poor spirits, one should drink tea. This will put the heart in order and dispel all illness. When the heart is vigorous, then even if the other organs are ailing, no great pain will be felt. . . . The heart is the sovereign of the five organs, tea is the chief of the bitter foods, and bitter is the chief of the tastes. For this reason the heart loves bitter things, and when it is doing well all the other organs are properly regulated. . . . When, however, the whole body feels weak, devitalized, and depressed, it is a sign that the heart is ailing. Drink lots of tea, and one's energy and spirits will be restored to full strength.13 _ This first Zen teacher was certainly no Lin-chi. He was merely a Tendai priest who imported Lin-chi's sect from China hoping to bring discipline to his school; he established an ecumenical monastery at which both Zen and esoteric Tendai practices were taught; he consorted with leaders whose place was owed to a military coup d'etat; and he appeared to advocate Zen on transparently practical, sometimes almost political, grounds. He compromised with the existing cults to the end, even refusing to lend aid to other, more pure-minded advocates of Ch'an who had risen in Kyoto in the meantime.14 But Eisai was a colorful figure whom history has chosen to remember as the founder of Zen in Japan, as well as (perhaps equally important) the father of the cult of tea.
