In order to understand the application of the techniques within the kata, it is useful to understand the feeling of the kata. One of the problems in learning these secrets is that they are not revealed casually or quickly. Many of the teachers who are able to truly transmit these teachings are located in Japan.

Without knowing genri (application) of entering and exiting each Kamae the ability to create henka may be limited.
