The truth of Zen is such that when we want to comprehend it penetratingly we have to go through with a great struggle, sometimes very long and exacting constant vigilance. To be disciplined in Zen is no easy task. A Zen master once remarked that the life of a monk can be attained only by a man of great moral strength, and that even a minister of the state cannot expect to become a successful monk. (Let us remark here that in China to be a minister of the state was considered to be the greatest achievement a man could ever hope for in this world.) Not that a monkish life requires the austere practice of asceticism, but that it implies the elevation of one’s spiritual powers to their highest notch. All the utterances or activities of the great Zen masters have come from this elevation. They are not intended to be enigmatic or driving us to confusion. They are the overflowing of a soul filled with deep experiences. Therefore, unless we are ourselves elevated to the same height as the masters, we cannot gain the same commanding views of life. Says Ruskin: “And be sure also, if the author is worth anything, that you will not get at his meaning all at once,—nay, that at his whole meaning you will not for a long time arrive in any wise. Not that he does not say what he means, and in strong words too; but he cannot say it all and what is more strange, will not, but in a hidden way and in parable, in order that he may be sure you want it. I cannot see quite the reason of this, nor analyse that cruel reticence in the breasts of wise men which makes them always hide their deeper thought. They do not give it you by way of help, but of reward, and will make themselves sure that you deserve it before they allow you to reach it.” And this key to the royal treasury of wisdom is given us only after patient and painful moral struggle.
