It is in "The Emptiness Chapter" that I write down the Way of the martial arts of the Two-Sword style.
The heart of emptiness is in the absence of anything of form and the inability to have knowledge thereof. This I see as emptiness.
Emptiness, of coures, is nothingness. Knowing the existent, you know the nonexistent. This, exactly, is emptiness.
To be in the world and see things poorly, to be unable to distinguish one matter from another and to regard this as emptiness - this is not true emptiness.
All that is just the mind in confusion.
When you are following the Way of the Martial Arts, you may perform this Way as a warrior, but if you are ignorant of the warrior's practies, you will not abide in emptiness. You will be confused and will not do the things that you should. Though you term this "Emptiness," it will not be true emptiness.
A warrior learns the Way of the Martial Arts with certainty, makes a strong effort in other martial accomplishments, and is not the least bit in the dark about the Way of conducting himself as a warrior.
He has no confusion in his mind and is never lazy at any moment of the day. He polished the two hearts of his mind and will, and sharpens the two eyes of broad observation and focused vision. He is not the least bit distracted by the clouds of confusion, but rather clears them away. You should know that this is true emptiness.
While you are yet ignorant of true Emptiness, you mayt think through your own certain way, relying on neither Buddhism nor the law of society, and think this is good.
But when you see things from the straight Way of the mind, taking in the world at large, you will see that each person will have the preferences of his own heart, and each eye will have its own distortions. Such distortions are turning your back on the True Way.
Know the meaning of this, and make the straightforward your foundation. make the Heart of Truth your Way, practice a broad spectrum of the martial arts and other arts, and understand the expansive correctly and clearly.
Accordingly, you will make Emptiness the Way, and see the Way as Emptiness.
