You might perhaps wonder how a method so utterly unpractical and speculative as that of trying to arrive at final enlightenment by pure contemplation could ever have taken root in Japan, among a people who, generally speaking, have never troubled themselves much about things apart from their actual and immediate use. An explanation of this is not far to seek. Eisai, the founder of the Rinzai school, the branch of the Contemplative sect first established on our soil, came back to Japan from his second visit to China in 1192 A.D.[15] This was the time when the short-lived rule of the Minamoto clan (1186-1219) was nearing the end of its real supremacy. Only fifteen years before that the world had seen the downfall of another mighty clan. The battle of Dannoura put an end to the Heike ascendancy after an incessant series of desperate battles extending over a century, giving our soldier-like qualities enough occasion for an excellent schooling. The whole country during this period had been under the raging sway of Mars, who swept with his fiery breath the blossoms of human prosperity, and the people high and low were obliged to recognise the folly of clinging to shadowy desires and to learn the urgent necessity for facing every emergency with something akin to indifference. To pass from glowing life into the cold grasp of death with a smile, to meet the hardest decrees of fate with the resolute calm of stoic fortitude, was the quality demanded of every man and woman in that stormy age. In the meanwhile, different military clans had been forming themselves in different parts of Japan and preparing to wage an endless series of furious battles against one another. In half a century too came the one solitary invasion of our whole history when a foreign power dared to threaten us with destruction. The mighty Kublei, grandson of the great Genghis Khan, haughty with his resistless army, whose devastating intrepidity taught even Europe to tremble at the mention of his name, despatched an embassy to the Japanese court to demand the subjection of the country. The message was referred to Kamakura, then the seat of the Hôjô regency, and was of course indignantly dismissed. Enraged at this, Kublei equipped a large number of vessels with the choicest soldiers China could furnish. The invading force was successful at first, and committed massacres in Iki and Tsushima, islands lying between Corea and Japan. The position was menacing; even the steel nerves of the trained Samurai felt that strange thrill a patriot knows. Shinto priests and Buddhist monks were equally busy at their prayers. A new embassy came from the threatening Mongol leader. The imperious ambassadors were taken to Kamakura, to be put to death as an unmistakable sign of contemptuous refusal. A tremendous Chinese fleet gathered in the boisterous bay of Genkai in the summer of 1281. At last the evening came with the ominous glow on the horizon that foretells an approaching storm.
