In hindsight the art can seem simplistic and obvious.
But it cannot be taught in a manner that allows the student this same viewpoint.

It is not a matter of obscurity or secrecy.
Even the most candid and forthright instructor cannot tell it verbally or show it physically.

The art must be experienced, first-hand, by the student.
This is what mysticism actually means: beyond words, beyond thought.

Corrections are always a sore point for students.

It is difficult for students to accept that even the most basic concerns deteriorate without correction, and that even the most familiar skills can be refined and improved.

A sword is not a toy.
It is an offensive weapon designed to pierce or cut the skin.

When you pick up a very sharp knife you are immediately cautious.
The slightest act of carelessness may result in a cut.
A blade can part skin easily.

Now, imagine a sword blade?
This is a dangerous weapon. It is not to be trifled with.

Performance art swordsmanship makes a mockery of the weapon; understating its seriousness.
