Dojo kun - Meaningful Advice, or Purely Decorative?

Has the dojo kun become obsolete?

With so little of the Okinawan and Japanese martial arts being practised and studied in buildings dedicated solely to the arts these days, even in Japan; I wonder how many beginners (people with less than 5 years training) are aware of a dojo kun? Not that you have to train in a purpose built dojo to obtain access to authentic information, for that you only need an authentic teacher. Nevertheless, if the building you train in is used for other activities you are less likely to be surrounded by objects of inspiration.

The dojo kun, as I understand it, is a direct communication from teacher to student. A compilation of thoughts that give deshi some insight into the things their sensei considers important. The kun not only impart information but reflect a level of personal insight; and for this reason alone you need to study the advice your teacher has taken the time to display.

Dojo kun are not rules, nor should they be treated like the Ten Commandments, they are however a signpost pointing you in the same direction as your teacher. If you are fortunate enough to practise your martial art in a permanent dojo, one that houses a kun, then make sure you give it more than a passing glance the next time you're there.
