" With the development of Zen, mysticism has ceased to be mystical; it is no more the spasmodic product of an abnormally endowed mind. For Zen reveals itself in the most uninteresting and uneventful life of a plain man of the street, recognizing the fact of living in the midst of life as it is lived. Zen systematically trains the mind to see this; it opens a man's eye to the greatest mystery as it is daily and hourly performed; it enlarges the heart to embrace eternity of time and infinity of space in its every palpitation; it makes us live in the world as if walking in the garden of Eden; and all these spiritual feats are accomplished without resorting to any doctrines but by simply asserting in the most direct way the truth that lies in our inner being.
