Sixthly, there is another characteristic of Zen, which cannot be found in any other religion-that is to say, its peculiar mode of expressing profound religious insight by such actions as the lifting up of a hair-brush, or by the tapping of the chair with a staff, or by a loud outcry, and so forth. This will give the student of religion a striking illustration of differentiated forms of religion in its scale of evolution.

Besides these characteristics, Zen is noted for its physical and mental training. That the daily practice of Zazen[2] and the breathing exercise remarkably improves one's physical condition is an established fact. And history proves that most Zen masters enjoyed a long life in spite of their extremely simple mode of living. Its mental discipline, however, is by far more fruitful, and keeps one's mind in equipoise, making one neither passionate nor dispassionate, neither sentimental nor unintelligent, neither nervous nor senseless. It is well known as a cure to all sorts of mental disease, occasioned by nervous disturbance, as a nourishment to the fatigued brain, and also as a stimulus to torpor and sloth. It is self-control, as it is the subduing of such pernicious passions as anger, jealousy, hatred, and the like, and the awakening of noble emotions such as sympathy, mercy, generosity, and what not.

The historical importance of Zen can hardly be exaggerated. After its introduction into China in the sixth century, A.D., it grew ascendant through the Sui (598-617) and the Tang dynasty (618-906), and enjoyed greater popularity than any other sect of Buddhism during the whole period of the Sung (976-1126) and the Southern Sung dynasty (1127-1367). In these times its commanding influence became so irresistible that Confucianism, assimilating the Buddhist teachings, especially those of Zen, into itself and changing its entire aspect, brought forth the so-called Speculative philosophy.[1] And in the Ming dynasty (1368-1659) the principal doctrines of Zen were adopted by a celebrated Confucian scholar, Wang Yang Ming,[2] who thereby founded a school, through which Zen exercised profound influence on Chinese and Japanese men of letters, statesmen, and soldiers.
