Peace was at last restored by Iye-yasu, the founder of the Toku-gana Shogunate (1603-1867). During this period the Shogunate gave countenance to Buddhism on one hand, acknowledging it as the state religion, bestowing rich property to large monasteries, making priests take rank over common people, ordering every householder to build a Buddhist altar in his house; while, on the other hand, it did everything to extirpate Christianity, introduced in the previous period (1544). All this paralyzed the missionary spirit of the Buddhists, and put all the sects in dormant state. As for Zen[FN#98] it was still favoured by feudal lords and their vassals, and almost all provincial lords embraced the faith. [FN#98] The So To Sect was not wanting in competent teachers, for it might take pride in its Ten-kei (1648-1699), whose religious insight was unsurpassed by any other master of the age; in its Shi getsu, who was a commentator of various Zen books, and died 1764; in its Men-zan (1683-1769), whose indefatigable works on the exposition of So To Zen are invaluable indeed; and its Getsu-shu (1618-1696) and Man-zan (1635-1714), to whose labours the reformation of the faith is ascribed. Similarly, the Rin Zai Sect, in its Gu-do (1579-1661); in its Isshi (1608-1646); in its Taku-an (1573-1645), the favourite tutor of the third Shogun, Iye-mitsu; in its Haku-in (1667-1751), the greatest of the Rin Zai masters of the day, to whose extraordinary personality and labour the revival of the sect is due; and its To-rei (1721-1792), a learned disciple of Haku-in. Of the important Zen books written by these masters, Ro-ji-tan-kin, by Ten-kei; Men-zan-ko-roku, by Men-zan; Ya-sen-kwan-wa, Soku-ko-roku, Kwai-an-koku-go, Kei-so-doku-zui, by Haku-in; Shu-mon-mu-jin-to-ron, by To-rei, are well known. It was about the middle of this period that the forty-seven vassals of Ako displayed the spirit of the Samurai by their perseverance, self-sacrifice, and loyalty, taking vengeance on the enemy of their deceased lord. The leader of these men, the tragic tales of whom can never be told or heard without tears, was Yoshi-o (O-ishi died 1702), a believer of Zen,[FN#99] and his tomb in the cemetery of the temple of Sen-gaku-ji, Tokyo, is daily visited by hundreds of his admirers. Most of the professional swordsmen forming a class in these days practised Zen. Mune-nori[FN#100](Ya-gyu), for instance, established his reputation by the combination of Zen and the fencing art. [FN#99] See "Zen Shu," No. 151. [FN#100] He is known as Ta-jima, who practised Zen under Taku-an. The following story about Boku-den (Tsuka-hara), a great swordsman, fully illustrates this tendency:
