The No To Ich Way of strategy is recorded in this the Book of the Void.
What is called the spirit of the void is where there is nothing. It is
not included in man's knowledge. Of course the void is nothingness. By
knowing things that exist, you can know that which does not exist. That
is the void.
People in this world look at things mistakenly, and think that what they
do not understand must be the void. This is not the true void. It is
In the Way of strategy as a warrior you must study fully other martial
arts and not deviate even al little from the Way of the warrior. With
your spirit settled, accumulate practise day by day, hour by hour. Polish
the twofold spirit heart and mind, and sharpen the twofold gaze
perception and sight. When your spirit is not in the least clouded, when
the clouds of bewilderment clear away, there is the true void.
Until you realise the true Way, whether in Buddhism or in common sense,
you may think that things are correct and in order. However, if we lood
at things objectively, from the viewpoint of laws of the world, we see
various doctrines departing from the true Way. Know well this spirit, and
with forthrightness as the foundation and the true spirit as the Way.
Enact strategy broadly, correctly and openly.
Then you will come to think of things in a wide sense and, taking the
void as the Way, you will see the Way as void.
In the void is virtue, and no evil. Wisdom has existence, principle has
existence, the Way has existence, spirit is nothingness.
