The Secret of......

Secrets.....you come across this all the time in martial arts. You'll read statements like ....unlock the secrets of Kata.....or the Secrets of Bunkai.....even of Budo.
The thing is, the people who are selling the 'Secret Idea' are those with the most to gain. Usually there are a series of books or DVDs that of course, You, and Me can buy.
What these salesmen are really doing is showing their vast experience over a number of years in a catalogued form.....

There are no secrets in Karate, only stuff that you haven't come across or discovered yet, realized or had insight of by whatever means.

Martial training and unlocking the secrets therein is quite simple. Keep training and you will discover them.....or not.
